CATDOLL : CATDOLL: How many days do you need to raise grasshoppers before you can sell them? (How many days do you need to raise grasshoppers before you can sell them? video)

1. What is the profit of raising grasshoppers per acre per year?

The growth cycle of grasshoppers is very short, generally only about one month, and they can grow strong and fat in no more than two months. In addition, the breeding cost is very low, mainly based on seedlings and greenhouse investment, and these two investments do not need to be invested again, so the longer the breeding, the higher the profit. The benefit per mu is about 50,000 yuan.

2. How about raising grasshoppers? What is the profit per acre? What is the initial investment?

1. You only need to buy seeds once, but they can reproduce for many years. Eggs hatch locusts, and locusts lay eggs, over and over again, endlessly, and never mutate. Each locust egg is calculated at 0.10 yuan, so 10,000 locusts only require an investment of 1,000 yuan. (Actual discount when purchasing seeds)

2. The breeding equipment is simple and can be made with whatever is available and local materials. The investment required to purchase some of the equipment is only a few dozen yuan.

3. There are many sources of feed. Locusts like to eat reeds, thatch, foxtail grass, thread grass, coiled grass, as well as corn, wheat, sorghum, millet, etc. There is no need to invest in raising 10,000 to 50,000 locusts. Each person can complete the entire process of feeding and management in two hours a day.

4. If you need to grow your own feed, you can plant 10,000 locusts in one acre of land in batches, and the investment is minimal.

5. Locusts have strong vitality and never get sick. Locusts are bred under natural conditions. In the north, two generations are produced in summer and autumn. In the south, they can be bred all year round. The cycle is short, the effect is fast, and the reproduction rate is high. Each locust lays 60 to 120 eggs at a time.

6. Raising 10,000 East Asian migratory locusts can reach 36-40 jin. Calculated at the current market minimum price of 10 yuan/jin, the calculation formula for summer locusts is: 10,000 × 36 jin × 10 yuan = 360 yuan. If 4,000 female summer locusts are left to lay eggs, each locust lays at least 60 eggs, and the survival rate is 90%, the number of autumn locusts in the second half of the year will be 4,000 × 60 eggs × 90% = 216,000, and the amount is 216,000 × 36 jin × 10 yuan = 7,776 yuan. The gross income in the first year of breeding is 7,776 + 360 = 8,136 yuan, which only requires an investment of 1,000 yuan and some simple materials. In subsequent years, depending on the number of eggs laid by the locusts, the income will double. (1. This is calculated based on two seasons a year. If more than two seasons are harvested each year according to our company's technology, the economic benefits will be more considerable; 2. If the initial investment is more than 1,000 yuan, then the development will be faster and the benefits will definitely double)

2. Locust breeding costs and profits

1. It costs 300 yuan to build a shed and 2,000 yuan to grow locusts. About 1,000 adults can be raised per square meter. Locust breeding is suitable for any family, including women and children. The scale can be large or small. You can start production with an area of ​​50 square meters and feed once a day. To build a shed, we just need to buy a better screen net, choose a place, build a shed of about 50 square meters, and organize people to go to the mountains to catch about 50X1000 locusts in the picture. The initial investment is about 500 yuan (excluding labor time and labor costs).

2. Benefit analysis: Buy 20,000 breeding eggs, with a reproduction rate of 85%, or 17,000 locusts, of which 50%, or about 8,000, are female locusts. Each female locust lays 40-80 eggs, and can lay 300,000-600,000 eggs, breeding 280,000-500,000 young locusts. Minus the 20% casualty rate, 220,000-440,000 adult locusts can be bred. Each 500 locusts weigh about one kilogram, and the output is 440-880 kilograms. The current market price is 20 yuan/kg, and the output value can reach 8,800-17,600 yuan. This income only requires an investment of 2,000 yuan in breeding eggs and greenhouse investment (note: these two investments are one-time investments and no further investment is required in the future). Since there is no need to continue investing in the second year, the profit will be even more considerable.

3. It only takes 35 days to raise locusts into adults, and they can be sold after they are fat and strong in about 50 days. A 200-square-meter net shed can raise 200,000 locusts (about 400 kg). The economic benefits are quite considerable, the cost is low, and the feed is mainly forage grass. The East Asian migratory locust has a wide range of feeding, just like feeding sheep. It likes to eat: reeds, thatch, foxtail grass, line grass, coil grass, etc.; Gramineae: corn, wheat, sorghum, millet, etc. Planting 1 acre of forage can solve all feed sources, with a short cycle and high efficiency. You only need to buy seeds once, and you will benefit for a lifetime. They can breed and raise dozens of times by themselves, and locusts can hatch from eggs and lay eggs, over and over again, forming a virtuous circle.

3. How many days does it take to raise grasshoppers before they can be marketed?

Grasshoppers grow very fast and can come out in 20 days.

4. When will artificially bred grasshoppers be available for sale?

About 40 days,

The grasshopper breeding cycle is generally about 40 days, and four batches can be raised in a year. In addition, the suitable temperature for grasshopper development is 25℃-32℃, relative humidity is 85%-92%, and soil moisture content is 15%-18%. When the temperature is lower than 14℃ or higher than 40℃, grasshoppers will gradually stop eating and die.

The minimum temperature for hatching eggs is 17 degrees Celsius, the suitable temperature for development is between 26-32 degrees Celsius, and the highest hatching rate is when the soil moisture content is 18-22%. It usually takes 50-60 minutes for the entire egg mass to hatch from the beginning to the end, and the maximum hatching time is from 8 am to 1 pm. There are also differences in the order of emergence during the hatching process.

5. How many months does it take to raise grasshoppers before they can be harvested?

Three months, but that thing in Mazhuang is not easy to raise

6. What is needed to raise grasshoppers?

Grasshopper Farming Preparation and Management Techniques

1. Preliminary preparations for raising grasshoppers

To raise grasshoppers, you need to build a breeding shed. It is advisable to choose a ventilated and sunny place, such as the front and back of the house, an idle courtyard, or a plot of land. The ground of the breeding shed should be 10-15 cm higher than the surrounding ground to facilitate drainage in the rainy season. The shed can be built with bamboo strips, bamboo poles, wooden sticks, etc. as supports, and then use gauze to make a greenhouse-like shed cover, bury the bottom edge in the ground, leave a door, install a zipper on the door or stick it with adhesive strips. The height of the shed is 1.5-2 meters, and it must be built by the end of April. The area of ​​the shed depends on the number of grasshoppers. Generally, 600-800 adults can be raised per square meter. At first, 15 square meters are enough to raise 10,000 grasshoppers. Each female locust can lay 60-90 eggs. As the number of grasshoppers increases, continue to expand the shed. After the breeding shed is built, dense wheat is planted on the ground inside the shed to prepare for the young locusts to eat.

2. Grasshopper Management

First, prepare non-toxic soil. Mix new sawdust and soil in a ratio of 2:1. The water content is 20%-30%. Spread 3-5 cm thick soil on the utensils or wooden boards, and then evenly spread the purchased grasshopper eggs on it. Cover the eggs with about 1 cm thick soil. After 10-15 days of incubation, all the grasshoppers will hatch around May Day. After the young locusts hatch, they shed their skin once every 7 days. Each shed is one age. After 5 sheds, they become adults. After another 50 days, the adults can be sold (260-340 grasshoppers per kilogram) or kept for seed and egg laying. During the 1st to 3rd age, the larvae eat very little. After 35 days, when they become adults, their food intake doubles. In addition to collecting some wild weeds for feeding, they can also cut artificially planted Mexican corn grass for feeding.

3. Precautions for breeding grasshoppers

1. Grasshoppers feed between 9 am and 5 pm, 2-3 times a day. When feeding grasshoppers, spread the fodder evenly in the shed.

2. The breeding shed should be properly covered in rainy weather, because if the ground is too wet, the grasshoppers will not eat and will die.

3. The breeding density should be 600-800 per square meter. If the breeding is too dense, the strong will eat the weak, the big will eat the small, or the ones that are molting will be cannibalized by those that molted earlier.

4. When the temperature in summer is above 35℃, shade the breeding shed and sprinkle some water on the gauze or in the shed to supply moisture. If the shed is too dry, it will also cause the grasshoppers to die.

5. If grasshoppers eat poisonous grass, they will die immediately. So if you don't know whether the grass is poisonous, it is best to wash it before feeding it.

6. The life cycle of grasshoppers is 75 days. Female grasshoppers will die normally after laying eggs, and male grasshoppers will also die normally after mating.
