Pour up the jointing fertilizer Topdressing with nitrogen fertilizer in the wheat rise and jointing stage can not only increase the protein content, but also increase the yield of wheat. Therefore, it is necessary to water the rise and jointing fertilizer according to local conditions. The grain yield and protein content of wheat depend to a large extent on the level of nitrogen supply during the developmental period. As the amount of nitrogen applied increases, the grain protein content increases. Apply 50% basal fertilizer, 50% jointing booting fertilizer, and attack grain fertilizer to prevent premature aging. In the case of suitable soil moisture and suitable soil strength and suitable seedling conditions, the first watering in spring should be postponed to the early stage of jointing to control excessive ineffective tillers in spring and the elongation of the first and second internodes of the stem base, combined with watering. Topdressing standard nitrogen fertilizer is about 30 kg per mu of water; for plots with higher soil fertility and prosperous seedlings, the fertilization can be properly delayed until the end of jointing; for plots with poor soil fertility and weak seedlings, it is the first time in spring Fertilization can be advanced to the wheat rise period before proceeding. Supplementing fertilizer and water in the middle and late stages Applying a small amount of fertilizer after the booting stage of wheat not only has a certain effect on reducing the degradation of flowering stage and increasing the number of grains per spike, but also can increase the protein content of grains and increase the quantity and quality of gluten. In the middle and late stages of wheat growth, 5-7 kg of urea per mu should be supplemented in combination with watering from the flag-picking and booting stage to the heading and flowering stage; 2% to 3% urea solution can also be sprayed on the leaf surface during the flowering stage, plus 0.3%～0.5% potassium dihydrogen phosphate solution, spray 50～60 kg per mu. Fertilizer and water in this period should not be too late, the soil fertilization is no later than the blooming period, and the foliar spraying is generally no later than the filling period. Properly control watering in the later stage The wheat milk is matured to the harvest stage, and watering is properly controlled to increase the gloss and keratin rate of the grains, significantly reduce the "black embryo" phenomenon, increase the protein content of the grains, and extend the stability time of the dough. Therefore, considering the simultaneous optimization of yield and quality, the number of watering should be properly controlled in the later stage of wheat growth.
