摘　　要：以温室连作土壤为试材,采用灌水高温闷棚技术,对西瓜连作的土壤酶活性状况及后期种植牛角椒的生长进行了研究。结果表明:灌水高温闷棚处理后,土壤细菌及放线菌含量升高,真菌含量降低,改善了植株根系微生物的群落结构;蔗糖酶、脲酶、碱性磷酸酶及脱氢酶活性下降,蛋白酶活性升高,其相关性有待进一步研究。It was researched that the soil enzyme activity changes of continuous cropping soil and the growth of green pepper after irrigating high temperature tightly greenhouse by using the technology of irrigation and high temperature tightly greenhouse.The results showed that after irrigating high temperature tightly greenhouse,soil bacterial and actinomycete content increased,microbial community structure of plant roots were improved,the enzyme activity of sucrose,urease,alkaline phosphatase and dehydrogenase were lower than contrast.The activity of protease increased,but there was no significant difference between control and treatment group.The correlation and effect of these changes needs further research.
