关中灌区是陕西夏玉米的高产区和主产区,常年播种面积达900万亩以上,占全省玉米种植面积的60%以上,总产占全省玉米产量近70%。抓好陕西夏玉米生产对于保障全省粮食供给,增加农民收入具有重要意义。该技术规程主要针对关中灌区夏玉米生产中品种繁杂,农艺操作不规范,农药、化肥施用过度,机械化程度不高等问题,通过集成创新“精选良种、合理密植、免耕直播、浇关键水、适时收获”等系列先进技术,并经过多年多点试验示范、推
Guanzhong Irrigation District is the high yielding area and main producing area of summer maize in Shaanxi Province. The perennial planting area is more than 900 mu, accounting for more than 60% of the corn planting area in the province, accounting for nearly 70% of the total maize output. Grasp the summer maize production in Shaanxi Province for the protection of the province’s food supply, increase the income of farmers is of great significance. This technical regulation mainly aims at the problems such as the variety of summer maize production in Guanzhong Irrigation District, the non-standardization of agronomic practices, the excessive application of pesticides and chemical fertilizers, the low degree of mechanization and so on. Through the integration of innovative “fine seed selection, reasonable close planting, , Timely harvest ”and other series of advanced technology, and after many years of trial and more demonstration, push
