| 摘 要： | 为有效利用秸秆资源,以研究最佳的秸秆还田方式,以玉米为研究材料,采用大田试验研究秸秆还田方式和数量对下茬作物产量构成因子及土壤肥力的影响。结果表明:鲜秸秆还田表现出对玉米株高、叶面积和产量构成因子(穗重、穗粒重、穗长、穗粗等)的促进作用,同时,半量秸秆还田对玉米产量的作用与腐熟猪粪的作用相当;半量秸秆还田对土壤碱解磷有促进作用,腐熟秸秆还田对土壤碱解氮的含量有一定提升作用。此试验条件下,半量鲜秸秆还田更有利于玉米产量的形成和肥力的提升。

| Abstract: | For effectively utilization of straw resources,and definte the best way of straw retumedf,taking maize as material,field experiment was carried out to study the effect of straw returned methods and amount on yield components and soil fertility.The results showed that fresh straw returned promoted the plant height,leaf area,and the yield components（including ear diameter,grain weight per ear,spike length,spike diameter etc.）.The similar results were observed on the maize yield between half amount of half amount straw return and the manure.The treatment of fresh straw return promoted the soil alkaline hydrolysis phosphorus and rotted straw promoted soil alkaline hydrolysis.Within the experiment results,half amount of fresh straw return favored for the maize yield and soil fertility. |
