When to plant cabbage seeds

Kale is a variety of vegetables, such as broccoli, cauliflower, kale and so on. At present, it is widely distributed in our country, and it can be seen in many areas. Because kale is very popular with consumers, so many people want to grow kale, the first thing is to know when it is planted.

Cabbage planting time

Cabbage planting time, suitable sowing time, early maturing seeds can be sowed from April to June, and the best sowing time is from June to early August.

The planting method of cabbage

1. Select varieties. The precocious varieties with short growth period are selected, the weight of single ball is about 1 kg, and the harvest time is about 45 days after planting, which is more suitable for consumers' consumption habits, and does not affect the sowing time of overwintering vegetables in the next crop, such as the Dutch variety Switzerland and so on.

2. sow seeds at the right time. The temperature requirement of cabbage seedlings is not strict, but the temperature requirement of heading stage is very strict, which should be about 17 ℃, which is beneficial to the formation and growth of leaf balls. Therefore, the summer sowing time is around the end of July. IV. Land preparation and planting

3. It is appropriate to select the legumes or melons whose previous crops are non-cruciferous, applying rotten organic fertilizer 3000 kg per mu, nitrogen, phosphorus and potassium ternary compound fertilizer 30 kg per mu, turning the land to make a border, the width of the border is 1.2m, planting 2 rows, the plant spacing is 40 cm, and protecting seedlings is 2500000 plants per mu. When the seedling grows to 5 ~ 6 leaves, the seedling is sprayed once before planting, that is, the seedling cluster is re-sprayed with 600x chlorothalonil and 3000 times Wanling in the seedling bed, and it is managed properly after planting. In general, there is no need to use drugs, and there is basically no disease during the whole growth period. Planting water should be timely, in order to slow down the seedlings, not dry seedlings.

Fertilization techniques of cabbage

1. The application of base fertilizer. After the harvest of the previous crop, 3000-4000 kg circle fertilizer was applied every 667 square meters as base fertilizer, deeply turned and raked flat to form a border 60-66 cm wide and a ridge 15-18 cm high. If the organic fertilizer is insufficient, after the soil is deeply ploughed and raked, 1000-2000 kg of rotten circle fertilizer is applied according to the row spacing of 667 square meters, and then ridge is supported and centralized fertilization is carried out to better exert the fertilizer effect.

2. The application of topdressing. Turnip cabbage has the characteristics of fertilizer tolerance, barren tolerance and strong absorptive capacity, but in order to achieve high yield, fertilizer and water management must be strengthened. In the vegetative growth stage of turnip cabbage, two times of topdressing can be carried out, and the first topdressing can be carried out after direct seeding or transplanting, applying 1520 kg of ammonium sulfate or 50kg of human feces and urine for every 667 square meters. The second topdressing was carried out in the peak period of fleshy root expansion, 25 kg of nitrogen, phosphorus and potassium compound fertilizer and 100 kg of plant ash were applied every 667 square meters. 750 kg of human feces and urine. Pay attention to watering after topdressing.

Insect pest control of cabbage

1. Cabbage catchment disease. Control measures: before sowing, seed was mixed with 65% mancozeb wettable powder of 0.3% seed weight. Disease-free new soil should be selected. The nursery bed should choose the land with high terrain, low groundwater level and good drainage. Sowing should be uniform and should not be watered as far as possible after emergence. When watering is necessary, a sprayer can be used to moisten the surface to avoid flooding. When the seedlings grow to 2-3 true leaves, it is best to use a seedling shovel. After dividing the seedlings, the water was properly controlled and the soil was covered for several times. Immediately after the disease, the diseased seedlings were removed and sprayed with 25% metalaxyl wettable powder 800 times, or 64% evil frost ·manganese zinc wettable powder 500 times, or 72.2% chloramphenicol 500 times, once every 7 days for 2 times 3 times.

2. Cabbage downy mildew. Control measures: before sowing, seeds can be mixed with 50% Fumishuang wettable powder of 0.4% seed weight or 75% chlorothalonil wettable powder. Rotate with non-cruciferous crops for 3 years and should avoid proximity to cruciferous crops. Nursery bed pay attention to ventilation and light, do not use low wetlands as seedbeds, combined with seedlings to remove diseased leaves and pull out diseased plants. Low wetlands are cultivated with high ridges and rational irrigation and fertilization. After harvest, the garden was turned over deeply.

Cabbage can be planted for a long time from late spring to late summer. When planting, you should choose the variety you need. In the later stage of planting, it is necessary to do a good job in fertilizer and water technology, and cabbage is also more vulnerable to insect pests, so pest control should also be done in place. Only when these are done well, the growth of cabbage will be better.
