First, pay attention to the selection of high-fertilizer land plots. High-yield and high-quality wheat varieties require that soil nutrients must be comprehensive and sufficient to meet the needs of their high-yield cultivation. Therefore, it is better to choose high-grade soils and well-watered conditions, and to increase the use of organic fertilizers. Formula fertilization technology.
Second, pay attention to appropriate late broadcast, according to the characteristics of the species, determine the appropriate basic seedlings. To prevent excessive broadcast, resulting in passive management later.
Third, pay attention to prevent lodging, reapply to start jointing fertilizer. At present, the promotion of high-quality wheat varieties, and some do not resist lodging, especially for large groups of wheat, in the return to the joints before the start of a chemical treatment, can be sprayed paclobutrazol Or Mai Yefeng. It is necessary to re-apply the joint fertilizer, to control the formation of extra falling ear, and to promote large grains and large grains.
Fourth, pay attention to pouring a good grouting water, wheat yellow water, spray foliar fertilizer, prevent premature aging. Pouring good grouting water, for increasing grain weight, to prevent dry hot wind has an important role. Dry weather, the use of wheat yellow water, is conducive to the next Interplanting to prevent premature senescence. In the middle and early May, combined with pest control, spraying 2 to 3 times of foliar fertilizer, such as 0.2% to 0.3% of potassium dihydrogen phosphate, can reduce the damage of dry hot wind, and the effect of increasing production is obvious.
Fifth, pay attention to the prevention of pests and diseases. Generally speaking, high-quality wheat is more susceptible to pests and diseases, such as wheat sheath blight, powdery mildew, locusts occur earlier and heavy than conventional varieties. Should be based on forecasting and early prevention and treatment.
