为了筛选出适宜湘潭县气候条件和耕作制度的秸秆腐熟剂,以“谷霖”、“九业”和“润邦”3种秸秆腐熟剂为材料,进行了秸秆腐熟还田晚稻种植试验。结果表明:秸秆腐熟剂可在短期内迅速降解水稻秸秆,改善土壤理化性状,提高土壤肥力;同时还可以改善水稻植株的经济性状,从而提高水稻产量、增加农民收益;其中以九业牌秸秆腐熟剂的增产效果最明显,比秸秆直接还田处理增产86.2 kg/667m2,增收226.52元/667m2,产投比高达7.06,其余两种秸秆腐熟剂的效果差异不大。因此,参试的3种秸秆腐熟剂均适宜湘潭县的气候条件和耕作制度,可在当地晚稻种植中推广使用。
In order to screen out the straw maturity agent suitable for climatic conditions and tillage system in Xiangtan County, three kinds of straw maturity agents such as “Gu Lin”, “Jiuye” and “Runbang” were used as materials to decompose straw Field late rice cultivation experiment. The results showed that: straw maturity agent can rapidly degrade rice straw in short term, improve soil physical and chemical properties, improve soil fertility; at the same time, it can also improve economic traits of rice plants, thereby increasing rice yield and increasing farmers’ income; The yield increase was the most obvious. Compared with direct straw returning, the yield was increased by 86.2 kg / 667m2, an increase of 226.52 yuan / 667m2, and the production / investment ratio was as high as 7.06. There was no significant difference in the effects of the two other straw decomposers. Therefore, all three kinds of straw maturity agents tested were suitable for the climate conditions and farming system of Xiangtan County, which could be popularized in the local late rice planting.
