1, choose high-quality wheat varieties. All the core demonstration films use good-quality complementary varieties; the county's semi-winter wheat varieties account for more than 90%, with Yannong 19, Shannong 17, Xunong 5, Mingmai 1, Luomai 23, Liangxing 66, Liangxing 99. , Huai Mai 22, Huai Mai 24, Shannong 20, Qin Nong 142, etc. as the dominant species. 2. Promote scientific sowing techniques. Focus on good sowing dates, appropriate planting, control of sowing, deep plowing, and fine soil preparation techniques, lay a good foundation for sowing, and focus on changing the bad habits of high-dose broadcasting, small row spacing, imprecise rotation, and shallow cultivation. Vigorously promote the use of small amounts of wheat seeding and deep plowing techniques to effectively expand and expand the spread of the seeding machine and strive to achieve a machine spacing of 20 to 25 centimeters. Under the premise of ensuring proper planting and pesticide seed dressing in appropriate periods, The seeding rate is controlled at about 10 kilograms, 8-10 kilograms for early and middle halberd, and 10-12.5 kilograms for late sorghum. Get early in the appropriate sowing period. For the semi-winter varieties such as Yannong 19, the suitable sowing date is October 10-20; the suitable sowing date for spring varieties is October 20-11. 3, scientific fertilization, nitrogen fertilizer shift. Scientifically using fertilizers: For plots with a yield of more than 450 kilograms per mu, require 4000-5000 kg of compost per acre, 12-14 kg of pure nitrogen, 6-7 kg of phosphorus pentoxide, and 5-7.5 kg of potassium oxide. Apply base fertilizer: Maixi "rich in the fetus," soil miscellaneous fertilizer, phosphorus, potash all basic facilities, nitrogen fertilizer 60-70% for the base fertilizer, 30-40% for the jointing fertilizer topdressing. In the flowering stage, foliar topdressing of 1-2% urea and 0.5-1% potassium dihydrogen phosphate solution should be carried out to reduce the degradation of floret, increase grain weight, and increase grain protein content. Foliar spray fertilizer is generally no later than the grain filling period. 4, strengthen field management. Pre-winter management to ensure that the whole seedlings, nurturing strong seedlings as the center, early seedling seedlings after sowing, to ensure that the whole seedlings broadcast. We vigorously promoted the former years of chemical weeding, made good efforts in the prevention and control of wheat spider mites, aphids, and overwintering water in case of drought to ensure safe wintering of seedlings. In winter or early spring, in the case of appropriate moisture conditions, timely cultivator cultivator, promote root development and cultivate strong seedlings. During the period of spring returning to jointing of green wheat, depending on the growing situation, chemical treatments such as spraying paclobutrazol and other chemical agents on wheat varieties such as tobacco farmers 19 that are resistant to the main culm can shorten the internodes of the wheat, increase the resistance of the stems, and increase the resistance to lodging. The spike rate. The timely irrigation and fertilization at the jointing stage drought can effectively reduce the deterioration of spikelets and florets, increase the number of grains per spike, increase the content of protein and wet gluten, and have a greater promoting effect on increasing yield. Attention should be paid to the prevention and control of pests and diseases such as sheath blight and powdery mildew. . Care should be taken to prevent and treat diseases and pests in the middle and late wheat crops, especially the prevention and control of wheat scab and ear blast. Spray foliar fertilizer to prevent premature aging, increase grain weight, and increase yield.
