[目的]为解决水稻秸秆自然腐熟过程慢、影响农耕等问题,开展水稻秸秆的最佳腐熟剂筛选研究.[方法]采用室内对比试验,观察不同时间秸秆腐熟的颜色变化,测定腐熟过程中pH、温度、种子发芽指数等指标,对比分析不同腐熟剂对水稻秸秆的腐熟效果,从而筛选出水稻秸秆的最佳腐熟剂.[结果]添加腐熟剂可缩短水稻秸秆的腐熟时间,提前7~14 d达到腐熟效果.宜春强微生物科技有限公司的强微堆肥快速腐熟剂处理后,在42 d时腐熟液pH达7.5,84 d种子发芽率达到85%,发芽指数为0.83,达到完全腐熟效果.[结论]相比其他处理,宜春强微生物科技有限公司的强微堆肥快速腐熟剂对水稻秸秆的腐熟效果最佳,可作为试验材料进行田间应用技术的研究与推广,从而为水稻秸秆的资源化利用和农业的可持续发展提供科学依据.%[Objective]In order to solve the problem of slow natural maturation of rice straw and the influence of farming,the experiment was conducted to select the best decomposing agent of rice straw.[Method]The laboratory contrast experiment was to observe the color change of straw maturity at different times and determine the pH,temperature,seed germination rate,seed germination index and other indicators of decomposition process,compare and analyze of the effect of different decomposing agents on straw,then select the best decomposing agent of rice straw.[Result] Adding decomposing agent could shorten the maturity time of rice straw about 7-14 days in advance. Under the treatment of the strong compost rapid maturity agent of Yichun Strong Microbial Technology Co.,Ltd.,the pH of rice straw reached 7.5 on 42 days,the germination rate was 85%,the germination index was 0.83 on 84 days and it achieved maturation effect.[Conclusion]Comparing to other treatments,the strong com-post rapid maturity agent of Yichun Strong Microbial Technology Co.,Ltd. is the best decomposing agent for the rice straw. It can be used as ex-perimental material to study and promote field application technology,in order to provide scientific basis for the resource utilization of rice straw and the sustainable development of agriculture.
