采用盆栽试验，研究了不同作物轮作和休闲方式对日光温室黄瓜连作土壤微生物数量、酶活性及后茬黄瓜生长和产量的影响.结果表明： 与连作相比，轮作有利于改善土壤微生物结构，增加细菌和放线菌数量，减少真菌数量；轮作与休闲有利于提高土壤转化酶、脲酶、过氧化氢酶和多酚氧化酶活性.在不同作物轮作和休闲方式下，后茬黄瓜结果期的细菌、放线菌数量和土壤转化酶活性均呈先升后降趋势，在盛瓜期达到最大值；真菌数量随生育期延长而增加；脲酶、过氧化氢酶和多酚氧化酶活性则随生育期延长而降低，在初瓜期最高.不同栽培模式下，以大葱-黄瓜轮作和糯玉米-黄瓜轮作的效果更佳，明显改善了后茬黄瓜的生长，提高了产量.
A pot experiment was conducted to study the effects of rotation and fallowing on the microbial communities and enzyme activities in a greenhouse soil continuously cropped with cucumber and on the growth and yield of followed cucumber. Comparing with continuous cropping, rotation improved the components of soil microbial communities, which was manifested in the increase of bacteria and actinomycetes and the decrease of fungi. Rotation and fallowing enhanced the activities of soil invertase, urease, catalase, and polyphenol oxidase significantly. The quantities of soil bacteria and actinomycetes and the activity of soil invertase increased at the fruiting stage of cucumber plants, being the maximum at harvest stage, but decreased thereafter. In contrast, the quantity of soil fungi had a linear increase, and the activities of soil urease, catalase, and polyphenol oxidase decreased gradually during fruit development. Welsh onion and waxy maize promoted the growth and fruiting of the followed cucumber plants significantly, being the optimal rotation crops for cucumber.
