In view of the difficulty of seedlings for summer vegetables, seed treatment should be done before sowing; and seedling diseases should be prevented and treated in time after emergence so as to ensure disease-free seedlings. In the process of raising seedlings, plastic film shall be covered to prevent rainwater from pouring into the seedbed so as to avoid root diseases; the insect nets shall be covered to prevent pests from entering; and the shade nets shall be protected against high temperature and seedlings shall be established to grow strong seedlings.
In view of the high yield of vegetables in summer, it is necessary to select heat-resistant varieties; to apply base fertilizers, pay attention to the combination of nitrogen, phosphorus, and potassium fertilizers, pay special attention to the use of potash; to strengthen the foliar fertilizer, pay attention to trace elements, spray zinc, boron, Micro-molybdenum fertilizer; growth potential should pay attention to spraying Yunda 120, love more to promote growth.
For those vegetables that are growing rapidly or growing up, fruits should be sprayed with chlorpromazine 2000-3000 times to promote their transformation into reproductive growth, in order to obtain good yields and benefits; for too many hours due to sunshine, melon Short-lived vegetables with less fruit need to be shaded for 4 hours a day to eliminate the effects of long days, meet short-day sunshine conditions, and promote the flowering of vegetables.
For diseases, in addition to doing a good job of seed disinfection and sterilization, they should also timely prevent and control various diseases such as downy mildew, early blight, late blight, anthrax, etc. after transplanting. For pests, attention should be paid to comprehensive prevention and control.
In short, only by picking up the difficulties of planting vegetables in summers, choosing varieties to adapt to the environment, changing the environment to adapt to vegetables, and planting according to market demand, can we grow more summer vegetables.
