摘　　要：通过采用免耕秸秆还田、免耕秸秆清除、秸秆还田耕翻、秸秆清除耕翻四种不同栽培模式,研究其对豆田蛴螬发生量的影响及对大豆产量的影响。结果表明:蛴螬发生量的表现为免耕田>耕翻田,秸秆还田>秸秆清除;在秸秆还田地块产量要素中,单株荚数、粒数增加较多,且翻耕田百粒重、单株粒重都最大;从产量上来看,耕翻田>免耕田,对免耕田而言,秸秆还田>秸秆清除,耕翻田则相反。经方差分析,产量结果未达显著水平。By using four different planting models： No-tillage and straw recycling; no-tillage and straws eliminating; straws return to soil planting; straws eliminating planting to study the effect of different planting models on grub occurrence in soybean field and soybean yield. The result showed that the grub occurrence＇ s order was as follow： no-tillage field〉 planting field; straws recycling〉 straws eliminating. In the production factors of straws recycling field, the single strain pods＇ numbers and total particles increased more, and its planting hundred grains＇ weight and sigle grain weight were the biggest. From the perspective of the production, the order was like this： planting field 〉 no-tillage field. In the no-tillage field, straws recycling field〉 straws eliminating field, and the planting field had the opposite situation. By the variance analysis, the production result didn＇t research the significant level.
