小麦、玉米“两晚”栽培技术是指在冬小麦、夏玉米种植区域内,通过适当推迟玉米收获期和小麦播种期,使小麦、玉米充分发挥生产潜力的节水、高产、高效栽培技术。近几年,受气候变暖的影响,平乡县小麦常出现冬前旺长、冬季和早春受冻的现象。9月下旬正是复播玉米灌浆的关键时期,农民习惯抢收,缩短了玉米生育期,影响产量的提高。玉米收获、小麦播种机械化水平的提高和夏玉米直播技术的推广,为玉米晚收技术提供了可行性。小麦、玉米“两晚”技术不需要增加农业生产成本,不需要进
Wheat, corn “Two nights ” cultivation technology refers to the water-saving, high-yield and high-efficient cultivation techniques that make the wheat and maize give full play to the productive potential in the winter wheat and summer maize planting areas by properly postponing the corn harvest period and the wheat seeding period . In recent years, due to the impact of climate warming, Pingxiang County wheat frequently appears before the winter long, winter and early spring frost phenomenon. Late September is the key period for compounding corn grouting. Peasants accustomed to snatch and harvest, shortening the growth period of corn and affecting the increase of output. Harvesting of maize, improvement of mechanization of wheat sowing and popularization of summer maize direct seeding technology have provided the feasibility for late harvesting technology of maize. Wheat, corn “two nights ” technology does not need to increase agricultural production costs, do not need to enter
