Application Status and Countermeasures of Chemical Fertilizer and Pesticide in Protected Vegetable in Laishui County

Abstract: In order to further promote the technological level of protected vegetable production, the greenhouse of Laishui county was investigated. Through the investigation of the greenhouse facilities and equipment, main crops, planting modes, sales channels, economic benefits and other basic conditions, it was found that there were some problems, such as backward basic supporting equipment, large differences in the management level of growers and so on. Based on the utilization of chemical fertilizers and pesticides in cultivation, it was found that there were some problems, such as excessive dependence on chemical pesticides, extensive application methods, lack of reasonable application scheme and poor awareness of safe use of chemical fertilizers and pesticides. Some cultivation management suggestions were put forward, containing reasonable irrigation according to the law of water demand, reasonable fertilization according to the law of fertilizer demand, as well as strengthening agricultural control (selection of disease resistant cultivars and crop rotation) and physical control (high temperature closed shed, covering with insect proof net and yellow sticky trap) and biological control (using biological pesticides, sex attractants and benefi cial organisms).
