一、试验目的施地佳盐碱土壤改良剂是利用有机营养剂给土壤微生物补充营养源,通过土壤微生物的代谢活动,使微生物活力加强,其分泌的有机酸能迅速降低土壤盐碱对作物的毒害。2009年引进施地佳盐碱土壤改良剂,在棉花地进行田间对比示范,研究其改良土壤效果,为大面积推广提供依据。二、试验地点 First, the purpose of experiment Shi Jia good saline soil improver is the use of organic nutrients to soil micro-organisms to supplement the nutritional source, through the metabolic activities of soil microorganisms, so that microbial activity increased, the secretion of organic acids can quickly reduce soil salinity on the crop Poisoning. In 2009, we introduced Shidijia saline soil improver to conduct comparative field demonstration in cotton field and studied the effect of soil improvement, providing a basis for large-scale popularization. Second, the test site
