摘　　要：了解＂圃园＂牌有机物料腐熟剂在稻草还田中的施用效果,选用3处理3重复随机区组设计,以新鲜稻草切短还田后,施入这种腐熟剂2.0 kg/667 m2。结果表明：稻草还田施入腐熟剂,可降低土壤容重,提高土壤有机质含量、p H值和养分含量,增产5.78%,水稻稻瘟病和白叶枯病的发病病情指数可降低16.71%~43.26%。这种腐熟剂可在澄迈县继续示范推广。In order to study the effect of the organic mater-decomposing inoculate＂Puyuan＂ on rice straw returning,the experiment of randomized block design with three treatments and three replications was conducted by applying ＂ Puyuan＂（2.0 kg/667 ㎡） on the chopped fresh rice straw returning. The results showed that applying ＂ Puyuan＂ on rice straw returning, could reduce the soil bulk density, raise the content of organic matter and p H value and soil nutrient, increase the rice yield by 5.78%, reduce the disease index of rice blast and rice bacterial blight by 16.71% ~43.26%. Therefore, ＂ Puyuan＂ should be demonstrated and popularized in Chengmai county.
