关于作物根茬对土壤酶活性的影响,过去很少研究。本文对黑钙土、黑土中各种作物留茬与否对土壤酶活性的影响作了分析。结果表明,各种作物根茬对土壤酶活性均具有一定的促进效应。但不同作物根茬的数量与组成不同,对土壤酶活性的效应也不同。玉米、高梁、草木樨、砂打旺等根茬的作用较好,大豆根茬的效应最低。因此,历来认为只有大豆是“养地作物”的传统观念,是值得商榷的。

The effect of crop stubble on soil enzyme activity has rarely been studied in the past. In this paper, the effects of stubble on soil enzyme activities of various kinds of black soil and black soil were analyzed. The results showed that all kinds of crop stubble had certain promotion effect on soil enzyme activity. However, the amount and composition of different stubble stubble different, the effect of soil enzyme activity is also different. The effect of root stubble such as corn, sorghum, malachite, sand and sand is better, and the effect of soybean stubble is the lowest. Therefore, it has always been argued that the only traditional concept that soybean is a “land-based crop” is debatable.
