摘  要:
为在茶陵县顺利推广应用秸秆腐熟剂,以"九业"、"豫园"、"湘润邦"3种秸秆腐熟剂为添加材料,2014年在茶陵县进行了稻草还田应用秸秆腐熟剂种植晚稻的小区试验。结果表明,稻草还田应用秸秆腐熟剂能有效地加速稻草腐熟速率,并能改善土壤理化性状,提高土壤有机质含量,降低土壤容重,增加土壤通透性,提高土壤保肥保水和供肥能力,最终提高水稻产量。晚稻实行稻草还田比不实行稻草还田增产4.6%;在稻草还田基础上应用秸秆腐熟剂比单独稻草还田不用秸秆腐熟剂增产6.0%;3种秸秆腐熟剂间的效果没有明显差异,都适宜在茶陵县推广使用。

摘  要:
To popularize and apply straw decaying agent in Chaling country smoothly, an experiment on straw returning to field was carried out by using "Jiuye", "Yuyuan" and "Xiangrunbang" straw decaying agents in late rice field of Chaling country in 2014. The results showed that decaying agents improved straw decaying speed in straw returning field. Besides, it improved the soil physical and chemical properties, increased the organic matter content of the soil, reduced soil bulk density, increased the soil permeability, improved the ability of soil fertility and water retention, and improved the rice yields. The production increased 4.6% in the straw returning field. And the production increased 6.0% in the field where straw decaying agents were used. And the effect of using 3 different kinds of straw decaying agents didn't have obvious differences, they were suitable to popularize and employ in Chaling.
