New tips for the management of greenhouse vegetables in autumn

1. Root irrigation and soil cultivation under the plant: eggplant fruit vegetables often die of diseases such as rhizome rot, wilt, yellow wilt, green wilt and so on. The application of organic humic acid liquid fertilizer and root Shitong can effectively degrade the salt damage of rhizome and inhibit the disease. In addition, soil cultivation is beneficial to the root of the stem and prolong the fruiting period.

two。 Remove old leaves, diseased leaves: eggplant fruits, melons, legumes, etc., after removing old leaf disease leaves, we should spray 600 times of new high-fat film in time, which can reduce plant nutrient loss and reduce the occurrence of diseases and insect pests.

3. Supplementary application of foliar fertilizer: foliar spraying of photosynthetic nutrient film fertilizer and foliar fertilizer can help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizer and nutrients to the limit of plant growth and development. One application is beneficial for the whole year.

4. Scientific epidemic prevention: greenhouse vegetables in autumn, the plant grows fast and the yield is high. However, due to the influence of high temperature and humidity, Phytophthora occurs quickly and spreads rapidly. it is necessary to spray 600-fold liquid of new high-fat membrane to form a polymer membrane to shield the predation signals of diseases and insects and weaken the transmission media. resist and defend against natural environmental disasters to improve epidemic prevention.

5. Ventilation, dehumidification and cooling: depending on the weather, crops, growth, etc., measures such as early tuyere closure, late tuyere opening, and midnight ventilation for half an hour should be taken to promote nutrient accumulation. Because the content of carbon dioxide in the air is high in this half hour, and the outdoor temperature is low, it is easy to drain moisture and cool air in the greenhouse vegetables.
