为验证大田条件下不同秸秆腐熟剂的应用效果,选择了3种秸秆腐熟剂,研究其对稻草还田腐熟程度、土壤理化性质、水稻生长发育及产量的影响。结果表明,施用秸秆腐熟剂对稻草还田腐熟效果明显:能有效缩短腐熟时间;能够改善土壤结构,降低土壤酸度和增加土壤有机质及养分含量;水稻产量显著增加,增产幅度为8.6%~10.3%,不同秸秆腐熟剂处理间的产量差异不显著。
In order to verify the application effects of different straw maturity agents under field conditions, three kinds of straw maturity agents were selected to study their effects on the maturity of straw, soil physical and chemical properties, rice growth and yield. The results showed that the application of straw maturity agent had obvious effect on the maturity of rice straw: it could effectively shorten the maturity time; improve the soil structure, reduce soil acidity and increase soil organic matter and nutrient content; rice yield increased significantly, the yield increase ranged from 8.6% to 10.3% There was no significant difference in the yield of different straw maturity treatments.
