摘　　要：依据在陕西延安日光温室内的田间试验，对黄瓜与不同作物建立的种植模式系统生产力与土壤生物特性进行了研究。结果表明，冬春茬黄瓜收获后采用不同的种植模式，其系统生产力与土壤生物特性发生明显变化。由小青菜、豇豆与黄瓜组成种植模式的系统产品生产力和经济生产力最高，翻青玉米、四季豆与黄瓜组成的模式次之。豇豆作为前茬处理的土壤呼吸强度最高，翻青玉米、四季豆、翻青黑豆和CK处理的土壤呼吸强度次之，番茄和小青菜处理的土壤呼吸强度较低。黄瓜收获后利用夏季休闲3～4个月对降低土壤细菌和真菌数量的效果最好，其次是种植豇豆或与豆科作物轮作。Based on field experiment which was conducted in plastic greenhouse in Yan＇an Shaanxi province, this paper researched system productivity and soil bio-characteristics of different cropping model between cucumber （Cucurnis statirus L. ） and other different crops. The results shown that after cucumber harvest, there was significant difference in different cropping model on soil bio-characteristics and system productivity. The system product productivity and system economic productivity were the highest in cropping model between cucumber and greengrocery, cucumber and cowpea, the second higher were in cropping model between cucumber and maize for green manure, cucumber and kidney bean. Soil respiration were highest in cropping model between cucumber and cowpea, the second higher were in cropping model between cucumber and maize for green manure, cucumber and kidney bean, cucumber and black bean for green manure, cucumber and follow, the lowest were in cropping model between cucumber and tomato, cucumber and greengrocery. That was the best way to reduce soil bacteria and epiphyte amount to follow lasting three or four months during summer season after cucumber harvest, the better method was planting cowpea or other legumina crops.
