摘　　要：采用田间试验,研究稻草全量还田配施腐解菌剂对机插晚稻生长发育的影响。结果表明,与单一秸秆还田(对照)相比,秸秆还田配施腐秆菌剂处理提高了水稻分蘖数、叶面积指数和地上部干物质量,增加了水稻穗数和每穗粒数,从而提高了水稻产量。从2年(2013、2014年)的结果来看,秸秆还田配施腐秆菌剂使干物质量提高了8.31%,植株N、P、K积累量分别提高了12.12%、11.97%、9.0%,产量提高了9.24%,效果显著。因此该自制腐秆菌剂可在当地秸秆全量还田机插栽培模式下使用。A field experiment was conducted in the growing seasons in 2013 and 2014 to assess the effects of straw returning plus straw decomposition agent on the growth of late rice. Straw returning in soil plus straw decomposition agent increased the number of tillers,leaf area index and above ground dry matter.And straw returning plus straw decomposition agent also increased the number of panicles per hm^2,number of grains per panicle and grain yield of rice.A treatment of single application of straw without decomposition was used as a control.With straw decomposition agent application,straw returning increased rice dry matter accumulation by8.31%,N,P,K by 12.12%,11.97%,9.0%,respectively,grain yield by 9.24%.Therefore,the straw decomposition agent can be used with straw returning in local machine-transplanted cultivation patterns.
