Abstract: To provide reference for rational fertilization and pesticide application in cucumber plantation, and relieve the problem of environmental pollution and vegetable pesticide residues, the authors discussed the effect of different combinations of fertilization and pesticide application on cucumber yield and cost input. Four treatments were conducted, including T1 (conventional fertilization+ conventional pesticide application, CK), T2 (conventional fertilization + recommended pesticide application), T3 (recommended fertilization + conventional pesticide application) and T4 (recommended fertilization + recommended pesticide application). The results showed that T4 had fewer kinds of fertilizers and pesticides than that of T1, and had yield increase effect on cucumber, the yield increase was 7003.5 kg/hm2 and the increase rate was 19.25% ; it also had obvious effect on cost-saving and benefit-increasing, the cost was saved by 10941 yuan/hm2 and the benefit was increased by 31951.5 yuan/hm2. The results of this experiment were satisfactory, higher benefit was obtained with lower input. The research could provide references for cucumber planter to choose fertilizer and pesticide, and lay a foundation for alleviating the ecological soil problems.
