Abstract: In this paper,influence of different fertilization mode on yield of cucumber and nitrogen accumulation and leaching of soil nitrate was systematically studied to explicit the optimum combined application of organic manure and chemical fertilizers under greenhouse condition.Based on a lysimeter experiment with undisturbed soil layers,plants,soil and leakage water were collected and detected.The results showed that compared with the chemical fertilizer application pattern,the yield and economic benefits increased by 12.1% and 7.1% under the combined application of organic manure and chemical fertilizers,with the highest yield and income for the combines application pattern of N1PK in chemical fertilizer and organic manure.At the same time,the combined application patterns of organic manure and chemical fertilizers significantly increased nitrogen accumulation,the increase of nitrogen fertilizer would only increase the accumulation of nitrogen in plant,no increase in fruit;The combined application patterns of organic manure and chemical fertilizers could significantly reduce the amount of leakage of irrigation water and nitrate nitrogen,the amount of leakage of irrigation water and the NO3--N leakage rates in the leakage water significantly decreased by 14.2% and 26.6% under the same chemical nitrogen application;Treatment of nitrogen application amount higher (OM+N2PK),the soil nitrate nitrogen appeared obvious accumulation.Thus,the combined application patterns of organic manure and chemical fertilizers could increase the yield and income,but also should be applied properly to reduce the chemical N fertilizer application;the pattern of combined application of N1PK in chemical fertilizer and organic manure under this experimental condition was the best.

Key words: Greenhouse cucumber, Combined application of organic manure and chemical fertilizers, Yield, Nitrate leaching, Nitrate accumulation
