With the development of intercropping and multiple cropping in recent years, the area of ​​late-seeding wheat has been expanding year by year. Due to the late sowing date, the time for seedling emergence after sowing of late-seeding wheat was prolonged, and the time for vegetative growth before winter was shortened. The number of spring leaves increased in spring and spring tillering is the main basis for tillering. When the late ear differentiation occurs later, the differentiation time is relatively short. According to the characteristics of the growth period of late sowing wheat, fertilization should break the fertilization method of “preferably using nitrogen as the main phosphate fertilizer†for the appropriate sowing wheat, emphasizing the principle of reusing phosphate fertilizer in the bottom fertilizer, supplemented by the principle of nitrogen fertilizer, because the phosphorus fertilizer promotes early maturation and accelerates The special role of the reproductive process, and can promote the development of the root system, is conducive to the deep rooting of wheat roots, enhance the vitality of the roots, expand the utilization of fertilizer and water in wheat, and enhance the wheat's resistance to stress. Root development is good, nitrogen uptake capacity is enhanced, and nitrogen utilization rate is increased, which promotes stable early growth of the wheat seedlings and more tillers, and improves the tillering success rate, which plays an important role in increasing panicle number. Re-application of phosphate fertilizer can make the flowering of wheat earlier 1-3 days, filling period extended 2-3 days, to provide for the possibility of late seeding early maturity and increase 1000-grain weight. In addition, potassium deficiency areas pay attention to increase potassium fertilizer in the base fertilizer. Under the premise of adequate fertilizer and water, spring wheat is topdressed with watering during jointing. It is not advisable to conduct fertilizer and water supply prematurely during the return period, resulting in many ineffective deliveries and late marriages. From the jointing stage to the heading stage, the absorption of nitrogen, phosphorus, and potassium reaches the highest peak. This period of fertilization helps to drive off the main stem, increase the percentage of tillers, and promote the differentiation of florets, reduce the degradation, and increase the number of grains per spike. . If there is no childbirth before sowing or the spring population is still insufficient, the fertilizer and water supply may be appropriately advanced and increased in order to increase the effective delivery and increase the number of mu ears. Pay attention to a balanced fertilizer, nitrogen, phosphorus, potassium, trace fertilizer with the application, the latter can be sprayed fertilizer to meet the normal growth of wheat needs. At the same time, it also plays an important role in improving the function of spring wheat leaves, especially the upper leaves, increasing grain weight and increasing yield.
