我省低洼盐碱地区面积很大,不仅盐碱为害,而且地薄缺肥,严重的影响作物产量。同时盐碱地区地多人少,耕作粗放,复种率不高,并有一部分多年弃耕的碱荒地;平原地区也有一些麦田夏季休閑。如何充分利用土地种植綠肥,以增加肥料培养地力,改良盐碱地,是值得研究解决的重要問題。为此,我省科研单位进行了綠肥引种与利用的研究,并針对盐碱地区的特点,着重选择抗盐
Low-lying areas in our province saline-alkali area is very large, not only saline-alkali damage, but also to lack of fertilizer, a serious impact on crop yield. At the same time more people in the saline-alkali areas, extensive farming, mulching rate is not high, and part of abandoned for many years alkaline wasteland; plain areas also have some wheat fields in summer leisure. How to make full use of land to grow green manure to increase manure fertility and improve saline land is an important issue that deserves to be studied and solved. To this end, the scientific research units in our province conducted a study on the introduction and utilization of green manure, and focused on the characteristics of saline-alkali regions, with emphasis on salt
