Summer cabbage cultivation technology

First, the variety: Xia You, Xia Yang, Xia Feng

 

Second, the soil preparation: It is best to use non-cruciferous vegetable fields, ploughing and drying for more than 7 days, 3000 kg of organic fertilizer per mu , or 50-70 kg of organic compound fertilizer . In order to facilitate drainage, it is necessary to use high ridge cultivation, which can be broadcasted or transplanted.

 

Third, sowing: take the hole sowing method, 50-70 grams per acre , plant line spacing 30 * 55CM , more than 4000 points per acre , using shade net cover cultivation best.

 

Fourth, field management:

 

　　 1. Water management: In summer, the high-temperature water disperses quickly. The soil in the field should be kept moist, and it should be prevented from being wet and dry. In high-temperature and dry weather, it is often necessary to pay attention to watering. It is generally better to water in the evening or early morning. Discharge water in time after rain to prevent flooding or cause disease.

 

　　 2 , fertilizer application: in principle, no topdressing, if the base fertilizer is insufficient, it should be in the rosette period and the core period, combined with watering per acre of urea or quick-acting nitrogen fertilizer 20 kg.

 

　　 3 , shade net cover principle: one cover and three cover three cover, that is, from sowing to emergence of continuous coverage; day cover, evening release, sunny cover, cloudy day, rain cover, rain after the release.

 

　　 4 , pest control: Xia Dacai mainly control downy mildew, soft rot, and viral diseases, mainly with 40% ethyl aluminum phosphate, 58% toxic manganese zinc, 50% DT, etc. The pests mainly include aphids, cabbage caterpillars, and noctuidae pests, etc., and are controlled by cypress, cypermethrin and the like.

 

V. Timely harvesting: The balling period of Xia Dacai happens to be in a high temperature and rainy season. The plants are easily infected with diseases, and the leaf balls are also prone to cracking. Therefore, when the cabbage cabbage reaches 70 % or more, it should be harvested in batches to reduce losses.
