土壤盐渍化是一个世界性的大问题,多年来国内外学者一直在探讨盐碱地改良途径。1983年我们采用了微区治理盐碱地的方法,提高植树成活率的效果显著.本文中的微区改土是指局部土壤的改良,小至1个树穴大至1条绿化带以至几亩绿地的范围。通过隔盐层、隔盐袋、腐殖酸肥料、过磷酸钙、酸化水等措施,使树木根际微区土壤物理状况、营养条件得到改良。这一方法投资少,见效快,简单易行。现将研究的结果整理如下。
Soil salinization is a big problem in the world. For many years, scholars at home and abroad have been discussing ways to improve saline land. In 1983, we adopted the method of micro-area management of saline-alkali land to improve the survival rate of tree-planting effect is remarkable.In this paper, the micro-area soil improvement refers to the improvement of local soil, as small as a tree hole to a green belt and even a few acres of green Range. The physical conditions and nutritional conditions of the rhizosphere soil in the rhizosphere of the tree were improved by means of separating salt layers, separating salt bags, humic acid fertilizer, superphosphate and acidified water. This method less investment, quick, easy. Now the research results are summarized below.
