Seed selection: varieties can be selected according to the climate of the planting place. Soil preparation: do not choose to sit on the ground, dig deep into the soil and apply base fertilizer. Sowing: you can choose to sow or raise seedlings in a seedbed. Management: the watering frequency is 3-5 days, the first fertilization should be carried out with weeding, and the second fertilization should be carried out when the leaves are rolled. Disease control: do a good job in the prevention and control of downy mildew and black root disease. Planting time: choose April in spring or September in autumn.

First, the planting method of cabbage

1. Seed selection

The main results are as follows: (1) the varieties of kale include kale, kale and purple kale.

(2) when selecting varieties, we can choose the right varieties according to the local climate.

(3) Hunan and other areas are more suitable for planting Brussels sprouts, the Yangtze River Basin is suitable for planting kale, and the dry northwest region is suitable for planting Brussels sprouts.

2. Land preparation

The main results are as follows: (1) the adaptability of cabbage is very strong, and there are no special requirements for soil and soil.

(2) when choosing a place, try not to choose a place to sit together, otherwise it is very easy to have a plague.

(3) when preparing the soil, pay attention to the need to clean up the sundries in the field, and then turn the land, and turn the land deeply.

(4) prepare for drainage while preparing the land, and dig a ditch every other meter in the field.

(5) when the land preparation is completed, it is necessary to sprinkle about 1 kg of farm manure and 50 kg of plant ash per mu as base fertilizer.

3. Sowing seeds

The main results are as follows: (1) the way of sowing can be carried out by direct sowing or by raising seedlings in seedling bed.

(2) when sowing, it is necessary to sow according to a certain distance, and then cover the seeds with fine soil and wait for seedlings to emerge.

(3) if you raise seedlings in a nursery bed, you need to spread the seeds evenly on the seedbed, then cover the seeds with thin soil, and then cover them with a layer of plastic film or withered grass to maintain the temperature of the soil. Transplant when the seedlings grow to 6-8 cm.

(4) the row spacing is about 40 cm and the plant spacing is about 35 cm when transplanting.

4. Management

(1) watering should be carried out after transplanting, and the frequency is about once every 3-5 days.

(2) if the seedlings transplanted in the field do not survive for various reasons, the seedlings need to be replenished within 5-10 days.

(3) the first fertilization should be carried out together with weeding, in order to make the seedlings better absorb nutrients and reduce unnecessary consumption, the amount of fertilization is about 100 jin of urea per mu.

(4) the second fertilization was carried out when the cabbage leaves were rolled, about 1000 jin of farm manure, 50 jin of potash fertilizer, 50 jin of compound fertilizer and 30 jin of phosphate fertilizer per mu.

(5) if the cabbage is loose when catching the ball, it needs to be tied up with straw.

5. Disease control

The main results are as follows: (1) the common diseases are downy mildew and black root disease. Downy mildew will affect the growth of cabbage leaves and form similar mildew spots on the leaves, which will wither the leaves in serious cases.

(2) Chlorothalonil is generally used to control downy mildew, and it is sprayed every 5-6 days.

(3) the prevention and control of black root disease is generally carried out before planting, and it is necessary to disinfect and replant it with quicklime during soil preparation, which can well prevent the occurrence of black root disease.

Second, the planting time of cabbage

The main results are as follows: 1. The planting time of cabbage is determined according to different climate in different regions, and the planting season is generally about April in spring or September in autumn.

2. According to the different planting time, there are spring cabbage, summer cabbage, autumn cabbage and winter cabbage on the market.

3. The suitable temperature for cabbage growth is 20-28 degrees. The cabbage planted at this temperature has high yield and good quality.
