| 摘 要： | 为了达到良好的还田效果，应采取合理的秸秆还田措施。通过秸秆还田的不同处理方式，对大豆农艺性状和产量进行方差分析和多重比较，结果表明：与普通翻地处理比较，秸秆覆盖还田、秸秆心土还田、秸秆焚烧处理在大豆植株株高、单株节数、单株荚数、单株粒数及公顷产量上均得到增加，秸秆心土还田处理的大豆单株节数、荚数、粒数和产量表现最好，与普通翻地处理间存在着显著性差异。并且与普通翻地比较秸秆心土还田增产32.31%，秸秆覆盖还田增产22.50%，秸秆焚烧增产13.65%，由于秸秆心土还田腐熟效果最好，促进土壤肥力增加，大豆吸收的土壤养分比较充分，所以大豆的产量较高。

| Abstract: | In order to reach a good effect on straw returning, reasonable measure of should be taken of strawreturning. By different processing methods of straw returning, the article made analysis on variance andmultiple comparison with agronomic characters and yield of soybean, the results showed that the plant height,single node number, pod number, grain number and yield of those three treatments were on the increasecomparing with the common ground treatments, those three treatments were the straw mulching, soil returning,and the burning of straw. The straw soil returning treatment was the best, and the different between themreached significant or highly significant. The yield of straw soil returning was more than 32.31% compared withcommon ground, the yield of straw mulching was more than 22.50%, the yield of burning of straw was morethan 13.65%. The yield of straw soil returning was the best, because of the good effect on well-composted, itwould promote an increase in soil fertilizers, and absorb the nutrients fully for soybean. |
