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 to study the effects of rice straw returning to soil with spoilage on growth and development of late rice. The results showed that compared with single straw returning (control), straw returning to the field with the application of the fungus agent increased the tiller number, leaf area index and aboveground dry matter, increased the number of panicle and grain per panicle, Thus increasing the yield of rice. According to the results of two years (2013 and 2014), the amount of N, P and K accumulated in straw was increased by 8.31% and the accumulation of straw was increased by 12.12%, 11.97% and 9.0% , Yield increased 9.24%, the effect is remarkable. Therefore, the self-made rot fungus agent can be used in the local crop straw returning mode.
