秸秆腐熟剂对水稻秸秆还田应用效果的影响研究

秸秆腐熟剂对水稻秸秆还田应用效果试验结果表明,水稻秸秆还田施用秸秆腐熟剂能提高水稻产量,最高增产850.5 kg/hm2,增产率8.4%。同时有效促进了水稻秸秆快速腐解,土壤容重略有下降、CEC值有所增加,对提高土壤保水保肥能力、培肥地力有一定的效果。

A Study of Influence of Straw Decomposition Additive on Application Effect of Returning Rice Straw to Farmland

The results of the experiment on the influence of the straw decomposition additive on the application effect of re-turning rice straw to farmland showed that the rice yield was increased by using the straw decomposition additive in return-ing rice straw to farmland and maximally the yield was increased by 850.5 kg/hm2 and the yield increase rate was 8.4%. It promoted the rapid decomposition of rice straw effectively, the volume weight of the soil decreased slightly and the CEC value increased to certain extent. It had certain effects on improving the water and fertilizer retention capacity of the soil and the fertility of the soil.
