The first is to save pesticides. Smaller wheat seedlings before winter, herbicides can be sprayed on the weeds to the maximum, thereby reducing the amount of liquid medicine. The second is to remove weeds easily. Most of the weeds in wheat fields in the early winter have just been unearthed. They are generally in the 3-leaf stage and have the lowest resistance. They are easily removed. The third is the small amount of pesticide residues. Before weeding in winter, due to the relatively long planting time of the crops under the loquat, the herbicide can be fully decomposed in the soil, thus reducing the herbicide residue in the soil, and will not affect the growth of the crop. Pre-winter chemical weeding note points: One should pay attention to selecting herbicides. To carefully read the instruction manual and use herbicides that have no effect on the crops under the crops, special attention should be paid to plots prepared for the cultivation of peanuts, soybeans, cotton and other crops sensitive to herbicides. Second, timely spraying. Generally, by the middle or late November, the weeds in the wheat fields have basically reached the same level. The chemical weeding time is preferably from mid-November to early December. Third, we must appropriately increase the amount of water. Take the Gongnong-16 manual sprayer as an example, the diluted herbicide solution per acre should not be lower than the two sprayers. Fourth, we must pay attention to spraying in windless weather, so as to avoid the influence of wind, resulting in uneven spraying.
