中文摘要：

为了研究温室生态经济系统氮、磷、钾营养物质流动规律,以＂津优1号＂黄瓜和意大利耐抽苔生菜为试材,在江苏大学农业工程研究院实验温室进行了基于配方施肥的＂黄瓜-生菜-黄瓜-生菜＂一年四茬复种试验。结果表明：作物对氮、磷、钾的吸收比例分别为56.04%、55.48%、42.40%,对氮、磷、钾的损失率分别达到40.38%、31.18%、56.17%。

英文摘要：

In order to investigate the rule of matter flow of nitrogen,phosphorus and potassium in greenhouse eco-economic system,an experiment on multi-cropping patterns of cucumber and lettuce based on the best fertilization prescription was made in experimental glasshouse of agricultural engineering institute of Jiangsu University by the material of ＇No.1 Jinyou＇cucumber and Italian lettuce.The results showed that,N uptake rate by vegetable was 56.04%,N loss rate was 40.38%,P2O5 uptake rate by vegetable was 55.48%,P2O5 loss rate was 31.18%,K2O uptake rate by vegetable was 42.40%,K2O loss rate was 56.17%.
