为了加快盐碱土灌区盐改步伐,防止土壤次生盐碱化,建设高产稳产商品粮基地。我们于1979至1981年在站内不同条田宽度(18米、25米、33米),不同排水沟深(0.3-0.5米、0.6-0.8米)的稻田、进行过盐改试验,取得了理想的效果,为进一步探索盐改的节水增产效果,为盐碱土灌区建设高标准的排灌工程提供依据。在省、市有关科研人员的参与和指导下,从1982年至1984年在梨树灌区砂壤质盐碱
In order to speed up the saline-alkali soil irrigation pace of change, to prevent secondary salinization of soil, building high-yield and stable production of grain base. From 1979 to 1981, we experimented with salt alteration on paddy fields of different widths (18 meters, 25 meters, 33 meters) and different depths of drains (0.3-0.5 meters, 0.6-0.8 meters) and achieved the ideal In order to further explore the effect of salt water saving and yield increase, it provides the basis for constructing a high standard irrigation and drainage project in saline-alkali soil irrigation area. Under the participation and guidance of relevant scientific research personnel in the province and city, from 1982 to 1984,
