February** Dynamic Incentive Plan Baby cabbage is a kind of leafy vegetables, which can also be said to be pocket Chinese cabbage, or miniature Chinese cabbage, young sprouts, is a subspecies of Chinese cabbage, which has a shorter growth period than Chinese cabbage, and the general growth period is 45 to 55 days. Baby cabbage has a delicate and smooth taste, making it an excellent ingredient for processed cuisine. In recent years, the market has risen first, due to the short production cycle, the economic benefits per mu are very considerable, and it is also one of the projects of high-efficiency seeds.
Baby cabbage is a variant of Chinese cabbage, which is a semi-cold-tolerant vegetable plant that is resistant to light frost and not severe frost. The average temperature of the most suitable growth is 17 22 degrees, the average temperature is higher than 25 degrees and the growth is poor, and the growth is slow below 10, the short-term low temperature of 0 2 degrees Celsius can still recover after freezing, and the long-term growth is frozen below minus 2 degrees Celsius, and the sowing temperature range should be 10 25 degrees.
Because baby cabbage prefers a cool climate, it can be grown in spring in general areas, and all year round in some mountainous areas, and the product is better.
The measures for planting baby cabbage are similar to those of Chinese cabbage, and the following points can be used to grow high-quality baby cabbage.
1. Choose the right seeds.
Spring planting should be done with early-maturing varieties that are suitable for local planting. At present, the varieties used in production mainly include Goryeo Chunyue Huang, with a growth period of 40 to 60 days. Goryeo golden doll, the whole growth period is 55 days. The growth period of Jingchun baby cabbage is 45-50 days. Golden boy baby cabbage, 40-45 days after planting, can be harvested.
2. Raise seedlings early and make full use of the appropriate growth period.
The baby cabbage is grown at a temperature of 25 degrees Celsius, and the spring climate is characterized by cooling first and then hot, if it is planted one day late, its growth period will be shortened by one day, and the yield of vegetables will be reduced. Therefore, in order to solve this contradiction, the seedlings are raised in early spring by using the yangqi, and transplanting is carried out at the time when the temperature rises to a suitable time for the growth of baby cabbage, so that the growth time is extended.
The time when baby cabbage can grow in the open field is in early April, so the seedlings can be sown in early March one month in advance, and the seedling age is one month.
3. Cultivate strong seedlings.
Seedlings are raised with yang furrow, bed soil is mixed evenly with fully decomposed soil miscellaneous fertilizer and field soil 50 each, and watered thoroughly for sowing, seeds are sprinkled evenly, and then covered with 1 cm of fine soil, and then covered with film insulation and moisturizing on the topsoil (seedlings are removed again), and the shelf cover film becomes a yang furrow, pay attention to heat preservation.
Before the seeds are unearthed, the temperature in the shed is controlled at more than 25 degrees during the day and about 17 degrees at night. After emergence, it is controlled at about 22 degrees during the day and about 15 degrees at night.
Do not rush to water the seedlings after they emerge, you can use spray moisturizing. When the true leaves are unfolded, they can be lightly watered with small water to keep the seedbed moist and not overwatered, so as not to cause diseases.
Carry out seedling refining about 7 days before transplanting, open the tuyere from small to large, and do not let it go all at once, so as not to cause cold damage. 4 5 true leaves can be planted.
Fourth, colonization. 1. Loose and fertilized soil: baby cabbage has a short growth period, and it needs loose and fertile soil to provide sufficient nutrients for the rapid growth of baby cabbage. Therefore, the soil should be deeply cultivated and plantar fertilizer should be applied before setting. Generally, 3 5 square meters of organic fertilizer are applied per mu, 80 100 kg of cake fertilizer, and 60 80 kg of compound fertilizer. If no organic fertilizer is prepared, it can be replaced by commercial organic fertilizer, and about 300 catties per mu are applied.
2. Planting density: planting in double rows of large ridges, with a ridge width of 60 cm, two rows on the ridge, a plant spacing of 25 cm, and about 8,000 plants per mu.
3. Planting should pay attention to the depth, do not press the center as the degree, first watering and then cover the soil, should not cover the soil first and then water.
5. Field management.
1. Cultivating: Before the rosette stage of baby cabbage, 2 or 3 times of cultivating should be carried out to loosen the soil to increase the ground temperature and promote the expansion of the root system. After slowing the seedlings, start a tillage, and squat the seedlings after tillage. The second is after squatting seedlings and watering, and the third is before the lotus sitting period.
2. Watering and fertilization: During the growth period of 40 to 50 days, water 4 or 5 times generally, before and after squatting seedlings, before and after topdressing and embracing the heart during the lotus sitting period, if it does not rain during these periods, it is necessary to water in time. Under the premise that the bottom fertilizer is sufficient, the lotus can be topdressed once in the early stage, and the compound fertilizer is 30 catties per mu.
3. Pest control.
Common pests and diseases of baby cabbage include aphids, cabbage worms, soft rot, etc. Because the growth period of baby cabbage is short, pesticides with less residues, such as biological pesticides, should be used for timely prevention and control, reduce pesticide residues, and ensure the safety of dishes.
