Detailed Explanation of Key Points of High-Yield Cultivation and Management Techniques for Chinese Cabbage
Chinese cabbage is the most common vegetable in China, with a wide planting area across the country. It is sown in summer, but sowing in summer does not mean that Chinese cabbage has a good ability to adapt to the high-temperature and heavy-rain weather of summer; on the contrary, these factors are all important factors affecting the yield of Chinese cabbage. Therefore, to achieve the goal of high yield of Chinese cabbage, correct management techniques are essential. Below, the editor brings you the high-yield management techniques for Chinese cabbage.
1. Land selection
Chinese cabbage requires a large amount of fertilizer and grows relatively well in fertile, loose soil. Plow and disinfect the land to avoid residual bacteria, and the drainage and irrigation system in the field should be relatively good to facilitate drainage. The location should be sunny, ventilated, free of pollution sources, and have sufficient water. Before sowing, mix farmyard manure into the soil and plow the field once to maintain soil fertility. If the soil moisture condition is poor, ridges must be made, and the ridges should be level. For easier cultivation later, apply ammonium bicarbonate together with soil and miscellaneous fertilizer when making the ridges.
2. Sowing
What affects the final yield and planting benefits of Chinese cabbage are the environment around the planting site and market demand at harvest time. At this point, these two aspects must be considered. In order to maintain healthy growth of Chinese cabbage and avoid the spring and autumn harvest periods, sowing is generally started in June-July. When sowing, it is necessary to apply New High-Fat Film together with the seeds into the soil, mainly to repel underground pests, avoid the occurrence of diseases, strengthen respiration at night, and increase the seed germination rate. And maintaining a reasonable planting density is the basic condition for achieving high yield.
3. Management
After sowing in summer, the weather is generally high-temperature and rainy, so when watering, water frequently and in small amounts, not too much, to avoid disease. However, if continuous high temperature and drought occur, keep the ground surface moist at all times to avoid sunburn. To prevent sunburn, certain shading measures should be taken. Over-summer Chinese cabbage is mainly managed by promoting growth, and when heading, watering and fertilizing should mainly use potassium fertilizer. Appropriately spray Zhuangjingling to improve the disease resistance of Chinese cabbage, minimize the amount of pesticides, and prevent burning damage.
4. Disease control
Chinese cabbage also encounters many pests and diseases during its growth process, and pest and disease control for Chinese cabbage is extremely important because Chinese cabbage has weak disease resistance. Once affected by disease and not treated in time, Chinese cabbage will die within 3-4 days, and if it is an infectious disease, it will spread relatively easily and affect a large area of Chinese cabbage. Diseases include sclerotinia rot and soft rot, among others, while pests include aphids and cabbage caterpillars, among others. If signs of disease are found in Chinese cabbage, targeted pesticide control should be carried out according to the actual situation, used together with New High-Fat Film to improve the control ability of the pesticide and strengthen the effect.
The above are several management key points compiled by the editor for the high yield of Chinese cabbage. Among them, pest and disease control is what the editor considers the most important. Disease-free seeds should be selected, and the soil should be disinfected. Prevent various pests and diseases, and do not give pests and diseases any chance to invade. If they occur, timely understand the condition and spray pesticides according to the symptoms. In severe cases, remove the diseased plants.
