周口市是全国小麦主产区。近年小麦单产、总产屡创历史新高,表现出冬小麦较大的增产潜力。调研发现,存在制约小麦再高产的八大因素:盲目用种、耕层过浅、盲目施肥、“白籽”入土、播期偏早、播种量大、忽视冬管、重虫轻病等。根据生产实际,提出相应技术改进方案:改盲目引种为适地选种,改耕层过浅为机耕深耕,改盲目施肥为配方施肥,改“白籽”入土为药剂拌种和土壤处理,改偏早播种为适期播种,改播种量大为适量播种,改出苗定乾坤为冬前分类管,改重虫轻病为病虫兼防。 Zhoukou City is the main producing areas of wheat. In recent years, the yield of wheat and the total output have hit record highs each year, showing a greater yield potential for winter wheat. The survey found that there are eight major factors restricting the yield of wheat: blind use, too shallow layer, blindly fertilization, “white seed ” into the soil, sowing earlier, sowing a large amount, ignoring winter pipe, insects and other minor diseases . According to the actual production, put forward the corresponding technical improvement programs: blindly introduced for the appropriate selection of species, too shallow layer of tillage for deep plowing, blind change of fertilizer for the formula fertilization, “white seed” into the soil for drug dressing and soil treatment , Sowing early sowing for the appropriate sowing, sowing the right amount of sowing the right amount of seedlings, change the seedlings for the pre-winter dry class classification tube, change pest and disease as a pest and disease prevention.
