CATDOLL : CATDOLL: How to manage asparagus in the first year (How to manage asparagus in the first year)

1. How to cut one-year asparagus seedlings?

Once a year, the asparagus seedlings need to be cut. They can be cut during the winter, which is beneficial for the plants to overwinter safely and can also promote the germination of new buds. When the asparagus grows to one meter, all the top growth points should be cut off to promote the germination of new buds. Excess branches and poorly growing stem buds should be cut off in time to avoid nutrient consumption.

How to deal with asparagus seedlings in the first year

1. Suitable lighting

Asparagus is suitable for growing in an environment with sufficient light, so when caring for asparagus seedlings in the first year, it is necessary to provide the plants with appropriate light so that the asparagus can carry out photosynthesis normally. When the light provided to the asparagus is too strong, it is necessary to provide appropriate shade for the asparagus to prevent the plants from being burned by excessive light.

2. Stay hydrated

Asparagus consumes a lot of water during its growth process, so when caring for the first-year asparagus seedlings, you also need to provide the plants with an appropriate amount of water, soak all the soil, and create a relatively moist growing environment for the asparagus. When watering the asparagus, you need to pay attention to the amount of water to prevent the asparagus from rotting due to water accumulation.

3. Provide nutrients

Asparagus is suitable for growing in a relatively fertile environment, so when caring for asparagus seedlings in the first year, it is necessary to provide the plants with reasonable nutrients to make the asparagus grow more vigorously. When providing nutrients to asparagus, the fertilizer can be diluted and provided to the asparagus so that the plants can absorb enough nutrients and grow better.

2. Do asparagus potted plants need to be repotted every year?

Yes. The method of changing the pot is as follows:

1. Do not water the pot a week before repotting. When the soil is dry, remove the asparagus completely, shake off the soil, and check the health of the roots.

2. Root repair: shake off the soil on the roots, simply comb the root system, find a clean pair of scissors, cut off rotten roots, old roots and withered roots, and rinse them with clean water.

3. Disinfection: Put the washed roots into potassium permanganate or carbendazim solution, soak for half an hour, then rinse with clean water and dry in a cool place.

4. Soil preparation: Make the soil loose and breathable. Half of the success of asparagus planting has been achieved. It is recommended that the ratio of ordinary nutrient soil: humus soil: coarse sand = 5:3:2.

5. Potting: first put a few small stones at the bottom of the pot, fill 1/3 of the soil, spread the asparagus roots, put them in naturally, after the soil is compacted, pour in root water, and then place it in a cool and ventilated place to slowly grow.

3. What should I do if asparagus grows too thin in the first year?

1. Stay hydrated

Although asparagus is a drought-resistant plant, if it is too dry during its growth period, the asparagus will grow too thin due to lack of water. At this time, it is necessary to replenish water to the asparagus in time and keep the soil slightly moist, which can promote the growth of asparagus.

2. Apply fertilizer

Asparagus requires sufficient nutrients to grow. If it lacks nutrients, the asparagus will grow too thin. If this happens, it is necessary to apply top dressing to the asparagus to meet the nutrients it needs for growth. Note that when fertilizing it, you must follow the principle of applying small amounts of fertilizer frequently. Fertilizers can be compound fertilizers and organic fertilizers.

3. Improve soil

Asparagus has certain requirements for the soil. It likes to grow in loose, breathable, well-drained and fertile soil rich in organic matter. If the soil salt content exceeds 0.2%, the development of asparagus will be affected, and it will grow too thin. At this time, the soil properties need to be improved in time.

4. How to plant and manage asparagus?

Planting method

1. Cultivate strong seedlings

To achieve high yield of asparagus, in addition to selecting excellent varieties, it is also necessary to establish a nursery for seedling cultivation. The most suitable time for establishing a nursery is June, and the seedling cultivation time is about 3 months. Sow seeds in the ridges, with a row spacing of 16.5 cm × 16.5 cm. The most suitable seedlings for transplanting are medium-sized seedlings with 10-20 roots.

2. Land preparation and transplantation

Asparagus likes to grow in moist sandy loam. Before transplanting, the soil should be plowed and loosened several times to remove impurities in the soil. After it is fully sun-dried (about 1-2 months), 4,000-5,000 kg of decomposed farm manure or 100-150 kg of cake fertilizer per mu should be applied, plus 150 kg of superphosphate and 30 kg of potassium chloride. The manure should be spread and then plowed. The cake fertilizer should be decomposed with water for 8-10 days and then mixed with superphosphate and potassium chloride. It should be applied in a 30-40 cm deep ditch, covered with soil, and then planted.

3. Reasonable density planting

The best time to plant seedlings is from August to September in autumn. The shoots are harvested in March to April of the following year. The time is short and the survival rate is high. The spacing between rows and plants is 25 cm × 160 cm. When planting, the roots are straightened and divided into two halves, fixed in the planting trenches, with the scale buds facing the center line of the ridge, and then covered with 5-6 cm of soil, compacted and watered enough to fix the roots.

4. Strengthen fertilizer and water management

1. Seedling stage: After planting, if furrow irrigation is used, water can be applied every 20-25 days. At the same time, drainage ditches should be opened to ensure that the ground is dry after the rain stops. Apply the first fertilizer 20 days after planting, and use 5 kg of compound fertilizer per mu and 1000 kg of water for hole application or furrow application. 40-60 days after planting, fertilize once every 25-30 days, and apply 25-50 kg of compound fertilizer or 10-20 kg of urea plus 6-12.5 kg of potassium chloride per mu. From 4 months after planting to before bamboo shoots are harvested, fertilize once every 25 days or so, and use 20 kg of urea and 12.5 kg of potassium chloride per mu for furrow application. Water should be applied after fertilization.

2. Harvest period: Fertilize every 15-20 days during the harvest period, with 20 kg of urea and 12.5 kg of potassium chloride applied per mu each time. At the same time, pay attention to opening the four-side ditches and the ditches in the field, drain the water on rainy days, and irrigate on sunny days.

5. Determine the mother stem

About 5-6 months after planting, when the seedlings produce the last batch of stems and the stems are 0.8-1 cm thick, the mother stems can be selected. Generally, 2-3 mature and pest-free strong mother stems are selected for each stalk, and then the excess, small or too thick stems are pulled out. Before the mother stems are determined, 30 kg of urea and 15 kg of potassium chloride are applied per mu of furrows. After the mother stems are selected, the ridges should be prepared and the soil should be piled up immediately to form 30-40 cm high ridges.

6. Prevention and control of pests and diseases

Common diseases of asparagus include stem blight and anthracnose. To prevent and control stem blight, spray 600 times of 70% thiophanate-methyl or 500 times of 40% carbendazim. Spray once every 10-15 days during the seedling and seedling stage, and once every 5-7 days during the mother stem selection period. To prevent and control anthracnose, spray 500 times of 70% mancozeb, 600 times of 75% chlorothalonil wettable powder, or 800 times of 80% anthracnose fumei wettable powder. Spray once every 10 days, 2-3 times in a row, but spraying is strictly prohibited 7 days before picking bamboo shoots. Common pests include cutworms and caterpillars. When the caterpillars are 1-2 years old, they can be sprayed with 1000 times of Anlubao. Older larvae of caterpillars and cutworms can be killed manually.

5. Should asparagus be pruned in the first year of planting?

Pruning asparagus in the first year

Reeds are often found near water and are particularly beautiful in their flowering season. Reeds play an important role in purifying sewage because their leaves, sheaths, stems, rhizomes and adventitious roots all have aeration tissue. Reed stems are tough and have a high fiber content, and are generally a rare raw material in the papermaking industry.

6. How to grow asparagus over the winter in the first year?

First, we need to clean up the fields and remove all dead branches and leaves.

The second is to mix lime and wood ash evenly and sprinkle it on the roots of asparagus. This can both keep warm and disinfect root pests, disinfecting two birds with one stone.

Third, drain the water in the ditch in time after the rain so that the asparagus roots can grow well.

Fourth, let the asparagus receive sunlight to improve its cold resistance. Doing these things well will allow the asparagus to survive the winter smoothly.

7. How to plant asparagus seedlings in one year?

one.

When selecting and preparing the land for planting asparagus, you should choose a plot with high terrain, convenient drainage, irrigation and sufficient sunlight. After selecting the plot, apply enough base fertilizer, use well-rotted farmyard manure, and apply 6,000 kilograms of farmyard manure per mu of land. Then plow the land again, and make sure the land is soft and fertile. Finally, ridges should be made, with a width of between 1.2-1.4 meters.

2.

When sowing asparagus seeds into the soil, you must choose high-quality and disease-resistant seeds. After choosing, soak them in warm water for a while, take them out and put them on wet towels to germinate. During the germination period, spray water frequently to promote the seeds to germinate as soon as possible. After germination, you can evenly spread the seeds on the soil surface, cover them with a thin layer of soil, and cover them with plastic film to keep warm and moisturize. If the environment is suitable, seedlings will grow soon.

3.

Timely planting: When the asparagus seedlings grow to 30 cm in height, they can be planted. First, dig a hole 30 cm deep and 30-40 cm wide, then put the asparagus seedlings into the hole, one asparagus seedling in each hole, and plant them at a spacing of 30-40 cm. Cover the soil in time after planting and irrigate thoroughly. Provide a warm and well-ventilated environment in the later stage, and the asparagus seedlings will soon resume growth.

8. How to deal with asparagus seedlings in the first year?

You can spray vegetable stem strengthening agent to activate the positive energy of plant ecological growth, widen the plant duct path, enhance the plant's ability to absorb water and fertilizer, and improve yield and quality. Add one capsule of vegetable stem strengthening agent to 15 kg to 30 kg of water. It can make vegetable seedlings grow vigorously, with thick stems and thick leaves, high yield and high quality.
