为了评价秸秆腐熟剂对稻草的腐熟效果,筛选出适宜铜梁县气候条件和耕作制度的秸秆腐熟剂,进行了稻草还田施用3种秸秆腐熟剂的试验探索。结果初步表明:(1)施用秸秆腐熟剂处理的稻草腐熟速度快、养分转化快,促使和加速了绿萍的生长;不同秸秆腐熟剂处理的稻草腐熟速度无明显差异。(2)秸秆腐熟剂能增加土壤有机质含量,施用金葵子牌秸秆腐熟剂比施用京圃园牌秸秆腐熟剂高6g/kg;施用金葵子牌秸秆腐熟剂比施用太阳雨牌秸秆腐熟剂高7.4g/kg。(3)参试的3种秸秆腐熟剂对水稻的增产效果没有明显差异,比不施腐熟剂处理增产2.5%～3.1%。
In order to evaluate the maturity effect of straw maturity agent on straw, straw maturity agent suitable for climatic conditions and tillage system of Tongliang County was screened, and three kinds of straw maturity agent applied to rice straw were explored. The results showed that: (1) straw maturity treatment with straw maturity speed, nutrient conversion quickly, to promote and speed up the growth of Greenpea; different straw maturity agent straw maturity speed no significant difference. (2) Straw matting agent can increase soil organic matter content. The application of Jin Kui Zi brand straw maturity agent is 6 g / kg higher than that of Jingpuyuan straw maturity agent. The application of Jin Kui Zi brand straw maturity agent High 7.4g / kg. (3) There was no significant difference between the three kinds of straw maturity agents tested on the yield of rice and 2.5% ~ 3.1% higher than that without applying the maturity agent.
