Pouring up the jointed fertilizer water to top up the nitrogen fertilizer during the jointing period of wheat can not only increase the protein content significantly, but also is a key period to increase the wheat yield. Therefore, it is necessary to use the jointed fertilizer water according to local conditions. The grain yield and protein content of wheat depend to a large extent on the nitrogen supply level during the development period. In the range of 16 kg of pure nitrogen per 667 square meters, the grain protein content increases with the increase of nitrogen content. In the fertilization, the fertilization method of “pre-promotion, central control, and post-reformation†is adopted, that is, 50% of the base fertilizer, 50% of the jointing and panicle fertilizer, and the weight-preserving and anti-premature aging. In the case of appropriate soil moisture, the ground cover is generally suitable for the ground conditions, and the first watering in spring should be postponed until the early stage of jointing to control the excessive growth of spring inefficient tillers and the elongation of the base of the stem. Watering per 667 square meters of standard nitrogen fertilizer is about 30 kilograms; for high ground strength and high seedlings, the fertilizer water can be delayed until the end of jointing; the soil is weak, the seedlings are weak, spring The first fertilizer can be carried out in advance to the start-up period.
Applying a good amount of fertilizer in the middle and late stages of fertilizer can not only reduce the flowering stage and increase the number of grains per spike, but also increase the grain protein content and increase the quantity and quality of gluten. In the middle and late stages of wheat growth, 5~7 kg of urea should be applied per 667 square meters in combination with watering from the picking stage to the heading and flowering stage. It can also be sprayed with 2%~3% urea solution at the flowering stage. 0.3%~0.5% potassium dihydrogen phosphate solution, spray 50~60 kg per 667 square meters. However, the fertilizer should not be too late in this period, the soil fertilization is not later than the flowering period, and the foliar application is generally no later than the filling period.
In the later stage, reasonable control of watering wheat milk to ripening stage, proper control of watering can improve the grain gloss and keratin rate, significantly reduce the phenomenon of "black embryo", increase grain protein content, and prolong dough stability time, so from yield and quality Synchronous optimization considerations should be properly controlled in the later stages of wheat growth.
