对昆明郊区蔬菜、花卉主产县典型大棚土壤进行取样和设施土壤土壤微生物区系和土壤酶活性分析,研究结果表明,与连作相比,花一花轮作最有利于增加土壤细菌、放线菌数量,降低真菌数量,提高土壤酶活性,花-菜轮作次之,菜-菜轮作模式效果最差。轮作能有效调节土壤微生物区系,有利于微生物群落的多样性和稳定性的提高,最终改善了土壤的微生态环境。
The results showed that compared with continuous cropping, flowers and rotations were the most beneficial to increase soil bacteria, actinomycetes Reduce the number of fungi, improve soil enzyme activity, flower - vegetable rotation, followed by vegetable - vegetable rotation worst effect. Rotation can effectively regulate the soil microbial flora, which is conducive to the diversity and stability of microbial communities, and ultimately improve the micro-ecological environment of the soil.
