Old Farmer's experience: cultivation techniques of vegetable shelter from Rain in Summer

Rain Water is concentrated from July to September in summer, the management of vegetable sowing and cultivation is difficult, and there is often a shortage in the market. The cultivation of vegetable shelter from rain is a cultivation method of covering the top of the greenhouse with plastic film to avoid direct dripping by Rain Water, but also can effectively improve the temperature and humidity conditions and achieve high quality, high yield and high efficiency of vegetables.

Supporting technology:

1. Suitable varieties are selected for temperature-loving and heat-resistant vegetables and fast-growing vegetables, such as tomato, pepper, eggplant, cowpea, bean, cucumber, Chinese cabbage, green cabbage, floating lettuce, lettuce, zucchini (seven-leaf melon) and so on.

two。 Timely planting according to the variety growth period and the middle period of rainfall, determine the sowing time and transplanting period, in order to achieve the best rain protection cultivation effect.

3. Increasing the application of organic fertilizer in summer high temperature and humidity environment, soil permeability is poor, plant growth, through the application of organic fertilizer to improve soil structure and improve soil fertility.

4. Properly sparse planting plants grow vigorously in summer, so it is necessary to appropriately reduce the number of sowing and transplanting plants, so that each plant can get good growth and development in limited space.

5. Timely ploughing and drainage in summer vegetables should be cultivated by ridge cultivation, and drainage and irrigation in and around the shed should be smooth. During the growth period, we should timely ploughing and weeding, timely and appropriate amount of irrigation, pay attention to drainage.

6. Timely pruning and shelving in summer, such as cowpea, bean, cucumber, tomato, eggplant and so on, should be pruned and sprouted and put on the shelf in time to improve the ventilation and light transmission conditions in the middle and lower parts of the plant to ensure the yield and quality of vegetables.

7. Strengthen the prevention and control of diseases and insect pests in summer high-temperature and high-humidity environment, conducive to the occurrence and spread of diseases and insect pests, timely and effective prevention and control. The main pests are thrips, whiteflies, cabbage insects, etc., which can be controlled by imidacloprid, acetamiprid, prolactin, Yitaibao, metoprolol and other pesticides; the diseases are mainly downy mildew, blight, powdery mildew and so on. Kelu, nail cream, manganese zinc, Pulick, Kesha, Anke manganese zinc, Fuxing, amicida and other pesticides can be used to control.
