玉米秸秆还田对土壤理化性状与小麦生长发育和产量的影响研究进展

Research Progress on Effects of Returning Maize Straws into Soil on Soil Physical & Chemical Characters and on Development and Yield of Wheat as Succeeding Crop

为给玉米秸秆还田技术的机理研究和推广应用提供参考,总结和分析了该技术的研究进展。秸秆还田对土壤物理性状、土壤水分含量、土壤有机质和矿质营养含量、土壤微生物和土壤酶活性,以及下茬小麦生长发育、产量及其构成因素、籽粒品质及麦田病虫害均有影响。未来该技术应增强增产机理、量化技术及配套技术方面的研究。

Patterns and methods of returning maize straws into soil,and the effects of returning maize straws into soil were comprehensively reviewed on soil physical characters,soil moisture content,contents of soil organic matters and mineral nutrients,activities of microbes and enzymes,as on plant growth and development,grain yield and its components,grain quality,and pests and diseases in the field of wheat as succeeding crop as well.Furthermore,current obstacles to returning maize straws into soil in wheat production practice were discussed,and several suggestions to those obstacles and prospects on yield-increasing mechanism of returning maize straws into soil and corresponding techniques were also put forward.
