    摘要:

    为明确秸秆循环还田对玉米生长发育和产量的影响,筛选合理的秸秆还田方式,于2000年设计了不同秸秆还田方式定位试验,通过对植株生长发育和产量构成等指标的测定及分析,结果表明,秸秆还田结合深松为作物生长发育创造良好的土壤环境,增加玉米单株叶面积,提高叶片光合能力,促进了干物质积累和产量提高,产量数据表明,全方位深松、高茬还田、粉碎还田和条带覆盖分别比现行耕法产量提高8.27%、13.50%、13.59和10.07%,增产效果明显。

    Abstract:

    In order to understand effects of straws returned into field on maize growth and development and yield and select proper mode of straws returned into field, the long-term located experiment about returned straws was designed in 2000. Indexes of plant growth and development and crop yield components were determined and analyzed. The results showed that deep tillage combined straws returned into field created a better soil environment for growth and development of maize. Leaf areas per plant of maize were increased, and capacity of photosynthesis was improved, so the dry matter accumulation promoted and yield enhanced. The data showed that yields of treatments of deep tillage, high stubble, crush straws returned into field, and belt cover increased by 8.27%, 13.50%, 13.59 and 10.07% compared with conventional tillage.
