| 摘 要： | 本试验探讨作物根茬对土壤团聚体的影响。测定结果表明:作物根茬留在土壤中能够增加水稳性团聚体的数量、玉米根茬优于其他作物,即玉米>高粱>谷子>大豆。玉米连作三年的优于连作二年的,玉米连作二年的优于豆茬玉米。玉米适当连作并且不刨除根茬,可以改善土壤的结构状况,还可收到培肥与增产的效益。

| Abstract: | The effect of crop stubbles qn soil aggregates , was studied'. The results showed that crop stubbles. Jreinainiag in the soil increased the amount.of water stable -aggregates. Corn 'stubbles, wersjtke most effective among the crops studied (corn, sorghum, millet,^soyb^an), Three-y's continuous cultivation of corn was superior to tworyaar^s. And the two^ year's continuous cultivation was also better than the corn fcgrowfl after soybean. Continuous cultivation of ;corn without Jremoving the stubbles can not only improve soil stru^ure but also fertilize the soil aadi increase the yield of the crop. |
