First, according to local conditions, for the wheat fields harvesting green onions after autumn, it is necessary to promptly smash the buried wheat seedlings in time. In the wheat fields without harvesting green onions, it is necessary to prevent the growth of the wheat seedlings, so as to avoid the subsequent harvesting of green onions to form more damage to the wheat seedlings.
Second, strengthen monitoring and timely control of pests and diseases. . At present, the wheat fields in our city have entered an important period of winter infection of various pests and diseases. It is necessary to carry out scientific prevention and control according to actual conditions and local conditions. To configure poisonous soil or bait to control underground pests, ensure that the whole seedlings are wintering. For wheat stripe rust, we must adhere to the strategy of “taking drugs for reconnaissance, local control, and discovering one point, controlling one piece†to minimize the source of wintering bacteria. The field where the sheath blight is up to standard should be controlled, and the general spray control should be carried out in the early spring next year to reduce the number of diseases in the middle and late stages. It is necessary to actively carry out comprehensive prevention and control of wheat pests and diseases to ensure the control effect.
Third, chemical weeding. Since the wheat sowing this year, the soil moisture is suitable and the temperature is high. The excavation rate of weeds before winter is higher than that of previous years. The current weeds are small in grass age, low in resistance, small in wheat, low in hiding, easy to spray and weed, and applied before winter. The safety interval is long, the control effect is good, and it is not easy to produce phytotoxicity. Select the right pesticide and carry out chemical weeding. The application time should be carried out when the daily average temperature is not lower than 5 °C. According to the occurrence of weeds, rational use of drugs. For the wheat fields with serious dicotyledonous weeds, such as pork mites, rice bran, sorghum, wild rapeseed, and leeks, can be controlled by giant stars and wheat stalks; monocotyledons based on maiden and wild oats Wet grasses with severe weeds can be controlled by thrips or oats.
