When planting Chinese cabbage, there is often the phenomenon of no leaf rolling and no inclusion, which is caused by improper fertilization, uneven water supply, and pests and diseases. In this regard, the following measures should be taken to make the cabbage tightly packed.
Rational fertilization. During the cabbage filling period, phosphorus fertilizer, potash fertilizer, and organic fertilizer should be added, and the amount of nitrogen fertilizer should be controlled so as to inhibit plant growth. Usually in the early stage of the ball and the middle period of the ball, each of the topdressing organic fertilizers is topped with potassium dihydrogen phosphate and tanning.
Scientific water supply. In the cabbage filling period, the water supply should be uniform and sufficient. Every morning and evening, the plants should also be rinsed with water for 1 to 1 kg each time.
Prevent pests and diseases. When pests and diseases occur in the Chinese cabbage cabbage, it is necessary to continue to spray 2-3 times of 1500 times of farmland music and 2,500 times of pyriconazole mixture.
Foliage top dressing. In the prevention and treatment of cabbage diseases and insect pests, sprayed in the liquid can be added 1000 times Green Fenway 1, 1500 times Shennongsu chelating fertilizer, 500 times Yunda 120 and other foliar spray together. Foliar top dressing can make cabbage tight.
Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries.
There is a conceptual overlap between plant extracts and herbal extracts. The raw materials of plant extracts in my country are mainly derived from Chinese herbal medicines, so domestic plant extracts can also be called Chinese medicine extracts to some extent.
