CATDOLL : CATDOLL: Where do you think natural kelp is produced in eastern Asia?

Where can you guess the production areas of natural kelp in eastern Asia?

The natural kelp production areas in eastern Asia include the northern coast of North Korea, the northern part of Honshu, Japan, the Hokkaido Strait, and the southern coast of the former Soviet Union, but the largest distribution is in Aomori Prefecture and Iwate Prefecture in Hokkaido, Japan. In addition, it is also distributed along the coast of Wonsan, North Korea. my country did not originally produce kelp, but after its introduction, it has also grown naturally in the fertile sea areas of the Liaodong and Shandong peninsulas in my country. At present, artificial breeding has been promoted to the coastal areas of Zhejiang, Fujian, Guangdong and other places, but it is a cold temperate species.

The quality and growth maturity period of kelp vary depending on factors such as the sea area, temperature difference from south to north, light, and seawater quality.

In my country, there are three major kelp production areas:

1. In the Xiapu area of ​​Fujian Province, the sea water is very clean, so the kelp grown here is of the best quality and the most expensive.

2. In Dalian, Liaoning Province, the kelp harvest period is from mid-May to mid-July every year, and the kelp is of good quality and very fresh, so the supply is in short supply.

3. In Rongcheng, Shandong, the harvest period is from mid-May to mid-July every year, and the output here is the largest. However, there are more industries in the north, and the seawater pollution is relatively serious, so the kelp leaves produced here are very wide, short and thick, and the taste is not very good, so the price is relatively cheap.

Marine economy

Rongcheng City, Shandong Province, known as the "largest fishing county in the country", achieved a total fishery income of nearly 4 billion yuan in the first half of this year, of which marine aquaculture and intensive processing of aquatic products accounted for 52% of the total fishery income. This is a welcome change after Rongcheng City implemented the adjustment of its marine economic structure, actively protected offshore resources, let aquaculture and intensive processing industries play the "leading role", and fishing industry retreated to the "supporting role".

For many years, offshore aquaculture in my country has been limited to the 15-meter depth line, which has seriously restricted the development of aquaculture. Rongcheng City has actively organized technical forces with advanced courage and explored the laws of deep-sea aquaculture. After years of exploration, it has finally overcome the technical difficulties of deep-sea aquaculture such as pegs and flow prevention, and successfully expanded the aquaculture area from the 15-meter depth line to the 30-meter depth line, opening the precedent for the national marine aquaculture industry. Their experience has been widely promoted and applied, greatly expanding my country's marine aquaculture area and generating huge economic benefits; in recent years, the low survival rate of abalone seedlings has been plaguing the seedling industry and hindering the development of abalone aquaculture. To solve this problem, the Xunshan Aquatic Products Juexin Group of this city and the Virology Department of Wuhan University jointly developed a disease prevention technology for abalone seedlings. Last year, they introduced parent abalone from Japan and carried out abalone hybridization, which was successful. That year, 8.9 million seedlings were raised at one time, and 6.6 million commercial seedlings were screened. This alone can generate a profit of 4 million yuan.

Rongcheng City has solved a number of technical problems in marine aquaculture, including high-altitude aquaculture, three-dimensional aquaculture, intertidal zone aquaculture and factory aquaculture, and has made major breakthroughs in light and temperature control for seedling cultivation, bait preparation, scientific feeding, comprehensive utilization of shrimp ponds, and introduction of new varieties.

At present, the city has 18 factory-style fish farms with a fish stock of 7 million; there are 34 factory-style abalone farms with a stock of 180 million abalone; there are 51 new species nurseries, which breed 4 billion units of various seedlings annually, and cultivate more than 30 kinds of famous and high-quality marine delicacies such as abalone, sea cucumber, pufferfish, American red fish, turbot, etc., with a total aquaculture water surface of 120,000 square meters.

Rongcheng City has also actively cooperated with dozens of domestic scientific research institutions and colleges and universities, such as the Institute of Oceanology, Chinese Academy of Sciences, the Academy of Military Medical Sciences, Chinese Academy of Sciences, and Shandong University, to study the development of marine organisms and deep processing industries, and has built a ready-to-eat, conditioned, convenient, and bionic food processing system led by Qiujia Aquatic Products Group, Yuanqiao Industrial Group, Jianing Aquatic Products Co., Ltd., and Taixiang Aquatic Products Co., Ltd., with fish, shrimp, and shellfish as the main raw materials; a processing system for intellectual health foods led by Hongyangshen Group and deep-sea fish oil as the main raw material; a processing system for iodine-containing health drinks led by Shentong Marine Bioengineering Company and Jinghai Fisheries Group and seaweed as the main raw material; a processing system for salted kelp series products led by the existing 20 key salted kelp production enterprises and kelp as the main raw material; and a feed processing production base led by the existing backbone fish meal production enterprises and low-value fish as the main raw material. Now we have cultivated a number of well-known and reliable product brands at home and abroad, including "Dain" marine biological medicines, "Hongyangshen" deep-sea fish oil pills, "Haizaobao" and "Jinhaida" seaweed beverages, "Haizhongwang" chitosan capsules, "Haodangjia" fast food, "Gaolv" brand salted kelp, etc.

All these have provided valuable experience for the development of marine life in depth and breadth in my country. In recent years, Rongcheng City has invested more than 1 billion yuan in science and technology in marine aquaculture and deep processing industries, and has researched and promoted more than 180 new technologies and achievements, 24 of which have been included in the "Spark" and "Torch" plans of Shandong Province and the "National 863 Plan". The contribution rate of scientific and technological progress to the growth of marine economy has reached more than 60%.

My opinion on the changes in Rongcheng education in the past 30 years of reform and opening up

In December 1978, the Third Plenary Session of the 11th CPC Central Committee was successfully held, opening a new historical period of reform and opening up. This is a great turning point in the history of our party since the founding of the People's Republic of China with far-reaching significance. The national economy has developed rapidly in the past 30 years, and our living and working conditions have also undergone tremendous changes in these 30 years. Food, clothing, housing, transportation, living environment and working conditions have all changed dramatically. The main spirit of the 17th CPC National Congress is reform. Reform is the driving force of educational development and the path of educational development. To study the spirit of the 17th CPC National Congress, we must use the idea of ​​reform to examine the historical process of educational reform, analyze the new issues facing educational reform, clarify the tasks and priorities of further deepening reform, unswervingly push educational reform forward, and provide inexhaustible motivation and institutional guarantee for building education with Chinese characteristics. Reform and opening up is a key choice that determines the fate of contemporary China, and it is the only way to develop Chinese characteristics and realize the great rejuvenation of the Chinese nation. "When discussing the adherence to the scientific outlook on development, it is pointed out: "We must implement the spirit of reform and innovation in all aspects of governing the country, unswervingly adhere to the direction of reform, improve the scientific nature of reform decisions, and enhance the coordination of reform measures. "Unswervingly deepening reform is the fundamental driving force for promoting modernization and building a well-off society in an all-round way. It should also be the fundamental driving force for giving priority to the development of education and providing education that satisfies the people. To study the spirit of the 17th CPC National Congress, we must use the idea of ​​reform to examine the historical process of education reform, analyze the new issues facing education reform, clarify the tasks and priorities for further deepening reform, and unswervingly push forward education reform to provide inexhaustible motivation and institutional guarantees for building education with Chinese characteristics.

Thirty years has passed in the blink of an eye! My personal experience over the past 30 years has allowed me to feel the pulse of social progress. The 30 years of reform and opening up have benefited the lives of every Chinese.

The past 30 years of reform and opening up have seen three decades of rapid social and economic development. Social material and cultural life have undergone earth-shaking changes. As an important part of reform and opening up, education reform has always attracted much attention. So, what changes have taken place in our city's education situation over the past 30 years of education reform?

1. Schools have transformed from exam-oriented education to quality-oriented education. Since academic qualifications have become an important basis for employment, the function of education has become utilitarian and single. The purpose of students going to school is no longer to learn knowledge and master skills, but to study for a piece of paper. In order to meet the actual needs of students, school education has become an education that exists for exams. The key to the comprehensive implementation of quality-oriented education is to correct educational thinking and establish new concepts of modern education. First, we must establish a correct view of educational goals. The educational goal dominated by exams must be changed. We must establish a quality education goal that aims to cultivate the noble ideological and moral sentiments, rich scientific and cultural knowledge, healthy bodies, good psychological qualities, strong practical and hands-on abilities of the educated, and fully develop individual characteristics, so that students can achieve comprehensive and harmonious development in morality, intelligence, physical fitness, aesthetics, and labor. Second, we must establish a correct view of talent. Countless examples from ancient and modern times, both at home and abroad, have repeatedly proved that people with high academic qualifications may not necessarily become talents. People without high academic qualifications can also gradually become outstanding talents in a certain aspect in practice as long as they have good comprehensive qualities. Third, we must establish a correct view of quality. Its main meaning is to completely abandon the outdated concept of judging success or failure by test scores and enrollment rates, and establish an education quality concept based on the comprehensive improvement of various basic qualities and the full development of individual characteristics. Fourth, we must establish a correct teaching concept. We must completely abandon the traditional teaching concept that simply attaches importance to "top" students and ignores ordinary students; emphasizes knowledge over ability, books over practice, indoctrination over inspiration, rote memorization over thinking, imparting over self-study, acceptance over creation, and classroom over extracurricular activities, and is centered on books, classrooms, and teachers; establish a modern teaching concept that unifies the whole student population with teaching students in accordance with their aptitude, teaching with educating people, imparting knowledge with developing intelligence, theory with practice, the leading role of teachers with the dominant position of students, in-class and extracurricular activities, and focuses on cultivating self-study ability and creative spirit. After the full popularization of higher education, the role of academic qualifications has gradually weakened. People have wantonly criticized exam-oriented education and strongly demanded that education return to its essence, return time to students, return health to students, and return ability to students. Education reform breaks the ice and moves forward. Various places have introduced measures to ensure students' rest time and encourage them to study and innovate independently. At the same time, colleges and universities have regained the autonomy of recruiting students. The rise of self-study, adult college entrance examination, and vocational education has broadened the channels for students to enter higher education. All of this has safeguarded the implementation of quality education.

Second, the high school education system has changed greatly. I remember the hardship of high school in the past. Students got up early and went to bed late, and teachers worked day and night. The entire education system was based on the promotion of higher education. Students had no personal freedom. Their only job every day was to study. Teachers seemed to be overwhelmed by the pressure of higher education. But since the spirit of the superiors was issued, everything has changed. Students have more time and can arrange it reasonably by themselves. There is no morning and evening self-study, and teachers are also less stressed.

3. Strictly implement the teacher positions and implement the teacher qualification certificate system in response to the requirements of the superior departments. Since the Teachers Law in 1993 stipulated the implementation of the teacher qualification system in my country, teachers have gradually changed from national civil servants to technical workers. Teachers are no longer "a brick that can be moved wherever they are needed", but have achieved two-way selection, self-selection of jobs, and competition for positions. The mobility of teachers has been strengthened, and teachers have consciously and actively strengthened their professional and technical literacy, realizing the centralized allocation of advantageous resources, optimizing the teaching staff, improving the quality of education and teaching, and attracting more outstanding talents to teach. It has opened up a channel for people outside the education system to teach, improved the social status of teachers, and laid a solid foundation for the scientific, standardized, and legalized track of teacher appointment.

Education is the foundation of a century-long plan. Under such circumstances, education reform has always been cautious and treading on thin ice, because education reform is related to the issue of talent training, and tuition fees cannot be paid. In addition, it is difficult for education reform to achieve immediate results like corporate reform, and there are many successful experiences to learn from. Therefore, the steps taken in education reform have not been big enough. We have been crossing the river by feeling the stones, but we always turn around by the river and cannot carry out drastic reforms. We still need to further strengthen the reform of education system, education model and education methods.

That's enough.

Rongcheng, one of the top ten attractive cities in China

From several perspectives 1. Jinghe Pangji Rongcheng used to be just a small fishing port county. Now there are all kinds of nuclear power plants and so on. You should know that as a Rongcheng person, you should have a way of bragging.

2. Environment: In the past, uncontrolled ocean fishing made our environment worse and worse. Now, we have developed from simple fishing to aquaculture and paid more attention to environmental protection. At the same time, we still have a developed marine industry.

3. More and more people from other places choose to settle in our hometown. There are many reasons. The transportation is developed. The Wei-Qing high-speed railway will be opened in two years. The pleasant climate...
