Due to the failure of the crops before the harvest period or the sowing of the rainy weather, the late sowing of the main crops is mainly characterized by little or no tillering before winter, small seedlings, weak seedlings, and poor root growth. According to the characteristics of less accumulated temperature, less roots, small seedlings, weak seedlings, and rapid spring development of late-seeding wheat, it is important to focus on the following six key measures:
First, adjust the varieties, to supplement the late Longnan to promote the 邯 6172, Wanmai 11 and other semi-winter quality wheat varieties.
Second, the appropriate increase in the amount of broadcast, in order to make up for the late Zhongnan area in October 15th, broadcast one night every night, 0.5 kg of seed per acre species.
Third, increase fertilization material, fertilizer supplement late on the premise of formula fertilization, increase phosphate fertilizer, with micro-fertilizer, micro-fertilizer application of 2 kg per gram of zinc fertilizer, boron 2 kg.
Fourth, skillfully pouring frozen water, postponing the spring water generally late broadcast wheat fields do not send frozen water, late spring water. In the event of an autumn drought, the frozen water should be poured early and the water volume should be small. The spring water time is generally from late March to early April, and nitrogen and phosphorus fertilizers are applied in conjunction with watering.
V. Loosening loosing soil, warming and protecting soils The late-seeding wheat fields are relatively weak and the population is relatively small. On the basis of realizing pre-winter strong seedlings and promoting hoeing, riprow soil. Regardless of whether they are frozen or spring water, they should be planted in a timely manner after burial so as to increase the temperature and keep the earth warm, increase the temperature, and promote the stable growth of wheat seedlings to ensure the number of panicles. In the later period, attention should be paid to preventing pests and lodgings and lodging, so as to ensure grain weight.
Sixth, spray surface fertilizer, increase the weight of grain growth in late spraying 0.3% potassium dihydrogen phosphate or special foliar fertilizer, such as green wind 95, Fur 655, Feng Bi Ling, etc., both fertilization and anti-dry hot wind.
