Planting and Management of Chinese Cabbage

Chinese cabbage planting first selected soil preparation, and then applied base fertilizer, mainly organic fertilizer; then sowed in time, and then did a good job of field management after emergence. Among them, field management should do a good job in seedling, topdressing, ploughing and soil cultivation, irrigation and so on.

Field management of Chinese cabbage

1. Interseedling: 2-3 true leaves, the first seedling; 5-6 leaves time the second seedling; 7-8 leaves can be fixed seedlings. Different row-plant spacing was selected according to different varieties, and one strong seedling was left in each hole.

two。 Topdressing: after the Chinese cabbage is planted and survived, you can begin to topdressing. 15% of rotten human feces and urine are collected every 3-4 days. When Chinese cabbage enters the rosette stage, the concentration of fertilizer should be increased, usually every 5-7 days, 30% of the feces of rotten acquaintances. After the beginning of heart care, the re-application of topdressing and potash fertilizer is a necessary measure to increase production. After the vegetation plants are closed, they are generally no longer topdressing. If the base fertilizer is insufficient, urea can be applied between rows as appropriate.

3. Ploughing and cultivating soil: in order to facilitate topdressing, loosen the soil in the early stage and weed for 2-3 times. Especially after a long time of rain and sunshine, the Kang field should be ploughed in time to promote the growth of the root system. In the middle of the rosette, cake fertilizer was applied to cultivate the soil in the middle stage of the rosette, which was 10-13 cm high. After the cultivation of manure into the furrow irrigation, can not be attached to the leaf sign; water into the ditch irrigation, do not soak the part. At the same time, the air circulation in the ditch was maintained and the air humidity between plants was reduced.

4. Irrigation: Chinese cabbage should be gently watered and moisturized at seedling stage; intermittent irrigation during rosette period, dry and wet, proper seedling training; high water requirement when heading, furrow irrigation can be used when the soil is dry. Irrigation should be carried out in the evening or after the ground temperature drops at night. Pour it in slowly and do not fill the bed. After the water seeps into the soil, the residual water should be discharged at extreme times. So that there is no water in the ditch, there is no water on the border, and there is no shortage of water in the root system.

In addition, the sowing time of different varieties of cabbage is different. For example, early-maturing varieties are generally sown in the first and middle of August, and some are sown earlier in late July. Medium-maturing varieties can be sown from late August to early September. Late-maturing varieties should be sowed in late August. We should determine the sowing time according to the actual situation.
