What are the new tips for managing greenhouse vegetables in autumn?
1. Root drenching and soil mounding under the plants: Solanaceous vegetables often die from stem rot, Fusarium wilt, Verticillium wilt, bacterial wilt and other diseases. Drenching with organic humic acid liquid fertilizer and applying root-promoting agents can effectively degrade salt damage in the root zone and suppress diseases. In addition, mounding soil around the base helps the stems root and extends the fruiting period.
2. Remove old and diseased leaves: For solanaceous, cucurbit and legume crops, after removing old and diseased leaves, promptly spray a 600-fold dilution of Xin Gao Zhi Mo (new high-fat film), which can reduce nutrient loss in the plants and lessen the occurrence of diseases and pests.
3. Supplement with foliar fertilizer: Spraying photosynthetic nutrient film fertilizer and foliar fertilizer on the leaves helps plants absorb large amounts of light fertilizer, light energy and light, is compatible with conventional fertilizers, and supplies nutrients to support plant growth and development to the fullest. One application benefits the whole year.
4. Scientific prevention of blight: In autumn greenhouses, plants grow quickly and yields are high. However, under the influence of high temperature and high humidity, Phytophthora blight pathogens develop quickly and spread rapidly. It is necessary to spray a 600-fold dilution of Xin Gao Zhi Mo (new high-fat film) to form a polymer film, blocking pest and disease feeding signals and weakening transmission vectors, resisting and defending against natural environmental disasters and improving blight prevention.
5. Ventilate to remove moisture and lower temperature: Depending on the weather, the crop and the growth condition, take measures such as closing the vents early, opening the vents late, and airing for half an hour in the middle of the night to promote nutrient accumulation. This is because during that half hour the carbon dioxide content in the air is high, and the outdoor temperature is relatively low, making it easy to remove moisture, lower the temperature and exchange air inside the greenhouse.
