Abstract: The input of water and fertilizer are far more than the crop demand in intensive greenhouse vegetableproduction． To meet sufficient supply of water and fertilizer in the root zone， the high input always lead to high Nloss， obvious P and K accumulation in the soil， and physiological deficiency in crops are getting more serious． Thekeys to maintain high quality and efficiency in vegetable production is to maintain optimal water and fertilizer supplyand keep healthy and good rhizosphere environment and to reduce unnecessary nutrient loss based on the cropgrowth． A summary of the keys to control high quality and efficiency vegetable production is presented: i． e． considering the nutrient balance concentration， form and nutrient ions in the root zone soil solution; reducing water leakageand maintaining water and nutrient spatially consistent． Combining with soil warming， applying the high C /N ratiomanure or straw to regulate the soil can promote the root growing， improve crops resistance and nutrient absorptionefficiency． The principle of applying the manure and chemical fertilizer in greenhouse production is controlling thetotal and regulation on stage; more times and less quality， application in rhizosphere and fertigation technologyshould be considered in N management; The constant monitoring rule of crop demand and maintain the soil fertilityshould be combined in P and K management; The principle of adjustment based on deficiency also should be adoptin secondary and micro-nutrients management． To achieve water and fertilizer high efficiency use and sustainabledevelopment of greenhouse vegetable， these principles and root zone management should be combined together．

Key words: Rhizosphere management, Critical nutrient supply, Root-inducing, High nutrient use efficiency, Fruit vegetable
