1. To seize the opportunity to irrigate the green water and apply green fertilizer to promote the weak and stable to control the prosperity. For plots that have not been watered for overwintering water or lack of moisture in winter, when the temperature reaches 5 degrees or more at the beginning of spring, water them in real time and apply green fertilizer. Try to slow down the progress of wheat watering. Just expand the watering area and separate watering, so that the wheat will turn green when the wheat is sprayed. Fertilizer, reaching the goal of promoting weakness, stability and control, lays a good foundation for high yield of wheat.
2. Superstition choose wheat herbicides to eliminate weeds in the field as soon as possible. The herbicide varieties should be selected according to the grass species of the weeds in the wheat field. Nowadays, the pesticides with better control results for dicotyledonous weeds in wheat fields include methuron, dimethyltetrachloro, tribenuron, etc. In particular, 20% make Taron 50-100ml/mu spray control, not only good control effect on weeds in wheat fields, such as shepherd's purse, wormwood, etc., but also safe for wheat; for the list of wild oats, Kan Mai Niang, etc. For wheat fields dominated by leaf weeds, 6.9% metsulfuron-methyl emulsion can be used to spray stems and leaves; for wheat fields where monocotyledonous and dicotyledonous weeds are mixed, a combination of the above drugs can be used; but keep in mind the period of herbicide use Usually before the rejuvenation stage to the jointing stage; when using it, it must be used in strict accordance with the proportion of the concentration and the technical operating procedures to avoid the occurrence of phytotoxicity.
3. Spray foliar fertilization to strengthen the plant's ability to resist stress. While chemically weeding, it is necessary to separate the foliar fertilizer and spray it according to the request of the agricultural technical staff. The foliar fertilizer is a compound type foliar fertilizer based on trace elements to quickly compensate for nutrients, slow down the transformation and promotion of seedlings, and strengthen Plant resistance to stress.
4. Strengthen the prevention and control of pests and diseases in the field. The prevention and control of diseases and insect pests can also be carried out simultaneously with separate chemical weeding, especially the prevention and treatment of wheat stripe rust and wheat field red spiders, aphids, midges, etc., which require close supervision and early prevention.
5. Beware of the "back spring cold" and late frost damage. After the jointing of wheat, the cold resistance is clear. Farmers and friends should pay close attention to the weather forecast, pay attention to temperature changes, and adopt methods such as watering and spraying antifreeze to prevent late frost damage before the warm current arrives. In the event of freezing damage, remedial measures such as watering and fertilization should be adopted immediately to promote the recovery and development of wheat seedlings as soon as possible.
