摘    要:稻草还田有利于土壤的可持续耕作,但往往影响土壤的当季生产力。以五丰优T025为供试作物,红壤为供试土壤,在大田条件下研究了微生物制剂在稻草还田中对土壤中微生物数量和酶活性的影响,并以水稻农艺性状和产量检验了土壤的生产力。结果表明,稻草全量还田并添加微生物制剂能够显著提高土壤中细菌、真菌和放线菌的数量,增强蔗糖酶、脲酶、过氧化氢酶和纤维素酶的活力;提高晚稻的单穗粒数、结实率、千粒重和产量。微生物制剂在稻草全量直接还田中具有较好的应用前景。

关 键 词:微生物菌剂  稻草还田  土壤微生物  土壤酶  产量

Abstract:Straw-returning isn’t only beneficial to the soil sustainability,but aslo influences on the soil productivity.Using the red soils and late rice Wufengyou T025 as the tested materials,we studied the influence of straw returning with straw decomposition agent on microbe,enzyme in rhizosphere soils and the late rice yield in field experiments.The microbial quantity,enzyme activity in rhizosphere soils were investigated with the different ways of straw return,and the soil productivity was examined with yield and agricultural traits of late rice.The results showed that straw returning with microbial agent could significantly improve the quantity of bacteria,fungi and actinomyces in soil,enhance the activity of sucrase,urease,catalase and cellulase,improve the grain numbers per spike and the 1 000 grain weight and yield.The straw returning with microbial has good application prospects.
Keywords:microbial agent  straw returning  soil microbe  soil enzyme  yield
