为评价“创博”牌和“保得”牌这2种秸秆腐熟剂在稻草直接还田模式下的应用效果,选用4处理3重复随机区组设计方案,以新鲜稻草粉碎直接还田,以晚稻种“博Ⅱ优15”为供试品种,研究这2种秸秆腐熟剂的施用效果,结果表明施用秸秆腐熟剂后,稻草达到最终腐烂状态要比自然腐烂缩短一半时间(即15 d),在促进稻草腐烂的进程上,这2种秸秆腐熟剂没有差异。稻草还田施入秸秆腐熟剂,可提高土壤有机质含量、pH值和养分含量,可增产3.36%~5.35%,可减少杂草19.32%~29.55%,可降低水稻发病病情指数9.77%~35.12%,在施用总体效果排序上,“创博”牌>“保得”牌>不施入秸秆腐熟剂的。这2种秸秆腐熟剂可以在澄迈县继续示范和推广。
In order to evaluate the application effects of two kinds of straw maturity agents, including Strawberry brand and Pauline brand, in direct rice straw returning mode, a 4-treatment 3-repeat randomized block design scheme was selected, and fresh straw was crushed directly The results showed that the application of straw maturity agent, straw to achieve the final decay than the natural decay of half the time (Ie, 15 days). There was no difference in the two straw composting agents in promoting straw decay. Rice straw into the straw maturity agent, can improve soil organic matter content, pH and nutrient content, increase yield 3.36% ~ 5.35%, can reduce weeds 19.32% ~ 29.55%, reduce the incidence of rice disease index 9.77% ~ 35.12% , In the overall ranking of the application, “Chong Bo ” brand> “Paul de ” brand> not applied straw maturity. These two kinds of straw maturity can continue to demonstrate and promote Chengmai County.
