The entire production process of organic Chinese cabbage must be carried out in accordance with the production methods of organic agriculture, that is, the production technical standards of organic food must be strictly followed throughout the production process, that is, no food is used during the production process. Pesticides, fertilizers, growth regulators and other chemical substances do not use genetically modified engineering technology, and must also pass the entire process of quality management and review by a separate organic food certification agency. What are the key points for growing organic Chinese cabbage?

1. Seed selection

Organic Chinese cabbage seeds cannot be genetically modified. Although genetically modified seeds produce higher yields of vegetables, they are not suitable for organic vegetable production. Chinese cabbage is generally produced in autumn and winter. The basic disease-resistant varieties include: Tianjin Qingmaye (Jinlu or Qiulu 75 and 80 series), Yutian Erbaojian, Yuqing, Beijing Xin No. 3, etc.

2. Land selection and preparation

The first and most important step in growing organic Chinese cabbage is to choose a pollution-free and beautiful environment planting base. The planting base should avoid places with serious damage such as factories and traffic thoroughfares. Ensure that air quality, water sources, etc. are in compliance with organic planting standards. Moreover, the previous crops in the soil layer cannot be cruciferous crops such as cabbage. After selecting the land, prepare the land well, plow it, make ridges, and plow it to a depth of about 30 centimeters. Then apply enough decomposed farmyard manure and appropriate organic fertilizer.

3. Watering

Watering should be sufficient within 24 hours before transplanting. After transplanting, the depth should be controlled according to the location of the planting soil layer, and then the Build up soil at the roots of cabbage. When the cabbage grows to the rosette stage, bio-organic compound fertilizer can be top-dressed appropriately and watered at the same time, because it can promote the decomposition of chemical fertilizers. During the bulbing period of cabbage, pay attention to the amount of watering, because if you are not careful, the leaves and stems may crack.

4. Fertilization technology

It is strictly prohibited to use chemical fertilizers. Use organic farmyard manure and bio-organic fertilizers approved by organic certification organizations, which can not only meet the needs of vegetable growth and development, but also make Vegetables can maintain their original taste, reduce inputs, improve land quality, and fertilize farmland.

5. Pest and disease control

Summer is hot and rainy, with long sunshine and serious diseases. Improving pest and disease control is the focus of summer cabbage cultivation. At this time, the seedlings are in the stage of high temperature and drought. If pests are not effectively controlled, viral diseases will become prevalent. After entering the season, heavy rains and high temperatures alternate, which is conducive to the occurrence of softening diseases and box mold. The main pests include aphids, cabbage caterpillars, etc. Pay attention to checking the leaves. When diseases are found, use organic vegetables to prevent and control them immediately.
