Chemical weeding technology in wheat field

Use safety-oriented varieties: Herbicides should not only be safe for crops, but also safe for crops. In order to improve the herbicidal effect, the herbicide variety should be selected according to the type of weed. According to the experimental research, the agents that have good effects on the control of broad-leaved weeds include superstars, 2,4-D butyl esters, and so on. Especially 20% make it long, and 50 to 60 ml spray per acre, not only For weeds with amaranth, sauerkraut, and piglet, it has good control effect, and it also has good control effect on weeds such as lacquer. 2,4-D butyl ester is susceptible to phytotoxicity to other crops such as cotton, and even the spraying of other medicines with other medicines sprayed with this medicine also has phytotoxicity, and attention should be paid when applying. For wheat fields with monocotyledonous weeds such as Mai Niang and wild oats, it can be controlled by spraying 6.9% Hummer 40-50 ml. For the wheat field where the broadleaf weeds and the single weeds are mixed, the acre can be controlled by spraying with 55% Pu'erke 120-150 ml.
Grasp the timing of prevention and control: weed control in wheat field has two periods of autumn seedling stage and spring wheat returning stage, and the autumn seedling stage is the best. After the wheat seedlings grow to 4 leaves (from mid-November to early December), it is suitable for weeding in wheat fields. At this time, most of the weeds have just been unearthed, the drug resistance is poor, and the control effect is good. One application can basically control the whole growth period. The weeds are harmful, and because of the early application time, the herbicide residues are small, and the impact on the crops is small. The chemical weeding period of wheat during the greening period is from late February to early March.
Strict dosage: If the amount of herbicide is too large, it will cause phytotoxicity to crops, and sometimes it will have adverse effects on the crops. If the dose is too small, the control effect on weeds will be poor, and the effect of weeding and wheat should not be achieved. Therefore, the dosage must be strictly controlled when applying the herbicide.
Guarantee the quality of spraying: Generally, the amount of medicine used for chemical weeding in wheat fields is 30-40 kg. When spraying, it should be sprayed evenly, and the wheat ridges should be sprayed to ensure the quality of prevention.
Note: When spraying herbicides, choose a windless sunny day, and resolutely disable metsulfuron-methyl, chlorsulfuron, tribenuron-methyl, wheatgrass, and wheat straw, and weeding the wheat field that can only be used in the rice-wheat cropping area. Injecting the drug strictly in accordance with the safe operation rules of the herbicide to ensure the soil and the environment are safe and pollution-free.
