我国粮食生产实现持续多年增产后,未来面临着单产难有突破性提高、农业投入不断增加影响农民效益等问题,笔者通过探索研究小麦由“三密一稀”变成“六密一稀”“五密一稀”“等行距”;玉米由“等行距”变成“扩行缩株增密”等作物种植模式的变革,在不增加投入的情况下实现作物增产。该模式在赵县生产上大面积推广,可为保障区域粮食生产安全提供科学支撑。
After China’s grain production has been increasing for many years, the future will face such problems as the breakthrough in yield increase and the increase in agricultural input will affect the peasants’ benefits. Through the exploration and study of wheat, the author has changed from “three to one” to “six to one Thin ”“ ”“ ”“ ”“ and other line spacing ”; corn from “ wait for line ”into “ expansion ”expansion “ reduction ”and other cropping patterns change, without increasing investment In the case of crop production increase. This model has been popularized in a large area in Zhaoxian production and can provide scientific support for ensuring regional grain production safety.
