为优化秸秆还田技术体系，采用2种快腐剂（腐秆灵、腐解菌）处理早稻还田秸秆，研究其对晚稻产量形成的影响。结果表明：快腐剂处理早稻还田秸秆，可促进晚稻分蘖，提高有效穗数；促进穗分化，提高每穗粒数与粒叶比；促进叶面积扩展，提高于物质积累量；对晚稻具有显著增产作用，增产幅度达8％～12％；腐解菌处理后的晚稻有效穗数、穗粒数、孕穗期叶面积指数、产量及茎鞘物质输出率比腐秆灵处理的分别提高1．7％、1．5％、4．3％、3．9％和17．45％，2种快腐剂处理的孕穗期叶面积指数和茎鞘物质输出率的差异显著。

Effects of treating early rice straw returning to field with two types of decomposition accelerant, Fuganling and straw-decomposition microbe, on yield formation of late rice were studied in double cropping rice field in Changsha, Hunan. The results showed the decomposition accelerant treated early rice straw had significant promoting effect on rice yield by promoting tillering and differentiation of spike and increasing leaf area thus enhancing effective-panicle number, grain number per panicle and ratio of grain number to leaf area and dry ma...
