With the decrease of temperature, the prevention and control of crop pests and diseases cannot be relaxed, and various measures should be taken in accordance with changes in temperature to ensure the smooth growth of crops. At present, it is a favorable period for fruit trees to use basal fertilizers. In combination with fertilization, look for rot lesions on trunks of trees, and root rot of root rot. After scraping or splaying the lesions, use bactericides such as fluorosiliconazole, propiconazole, or difenoconazole to spray concentrations. Add 10 times the dose of cytokinin and smear it on the wound. For root rot, it is best to remove the soil around the diseased root and replace it with new soil. In wheat fields where wheat is prone to bushy dwarf disease, wheat is sprayed immediately after the emergence of seedlings, and antiviral agents such as tycophora and virus A are used to reconstitute insecticides such as pyrethroids and imidacloprid, to eradicate the poisoning pest, Laodelphax striatellus, and to control the golden leafworm. Improve wheat anti-virus ability. After more wheat fields with grassy weeds and three leaves of wheat, we chose fenoxaflorin (wild oats), methylsulfuron (wild oats, bluegrass, etc.) for the main dominant weed population in sunny and warm weather. Grass), chlorsulfuron-methyl (Brazil), clodinafop-propargyl (wild oats, hardgrass, and maimai) were used to control grass weeds. During the daytime, greenhouse vegetables should be extended as long as possible. In the evening, keep warm. If the temperature is too high or too low, vegetable growth disorders will occur, and downy mildew, keratoderma, leaf mold, gray mold, sclerotinia and other diseases will be induced. Therefore, vegetables in greenhouses at this stage should be lightened, tempered, controlled, fertilized, sprayed once every week or so, a protective bactericide or therapeutic bactericide to protect the leaves and fruits.
