- 摘要:
- 为促进南疆农业资源可持续发展，以腐熟棉花秸秆有机肥为试验材料，研究其对土壤理化性质及棉花产量的影响。试验分为两组AOF（试验组）和CK（对照组），两组试验面积均为6.67 hm2，在相同环境和管理模式下进行。结果表明：AOF有机质较CK组提高23.68%，土壤微生物有效活菌数得到提升，土壤中的钾含量增加；在花铃期测得AOF茎的直径较CK组提高5.77%，结铃数和收获株数分别提高5.39%和17.05%。说明施用有机肥可改善土壤结构及其内环境、对土壤的肥力具有良好的改善作用，并可在一定程度上增强棉花的抗逆性，能够缓解长时间连续种植同一种作物对土壤理化性质、作物生长性状及产量的不利影响。
