肇东县位于我省西部,是松嫩平原中部的苏打盐碱土地区之一。全县307万亩耕地中,苏打盐土、碱土和盐碱化土壤约占三分之一左右。其中以轻碱土居多,中度盐碱化土壤次之。轻碱土盐份含量为0.1—0.25％。这类土壤由于沙粘比例不当,质地粘重,垦后耕性差,有效肥力低,因而前期不发苗,后期抗灾能力差,一遇低温早霜年份,常因作物贪青晚熟,致使粮食产量大幅度下降。为尽快结束粮食产量大幅度波动的历史,实现稳产高产,改良盐碱土已成为当务之急。为此,现将我们在涝洲公社改良盐碱土技术措
Zhaodong County, located in the western part of our province, is one of the soda saline-alkali soil areas in the middle of the Songnen Plain. The county 3070000 mus of arable land, soda salt, alkaline earth and saline soil about one-third. Among them, most of light alkaline soil, followed by moderate saline soil. Light alkaline earth salt content of 0.1-0.25%. Due to the improper proportion of sand-sticking, thick sticky soil, poor cultivating ability and low fertility after cultivation, this kind of soil has no early seedling stage and poor disaster resistance in the late stage. Decline. In order to end the history of sharp fluctuations in grain output as soon as possible, it has become a top priority to achieve stable and high yield and to improve saline-alkali soil. For this reason, we will now improve the technique of saline-alkali soil in the Waterlogged Island Commune
