当前影响黄瓜产品质量安全的主要有害类型有工业的“三废”污染、农药残留污染和硝酸盐累计污染三种类型。因此,无公害黄瓜栽培也就从解决这三方面问题入手。一、选择无公害黄瓜生产基地无公害黄瓜生产基地选择的基本原则是:生态条件良好,远离污染源,并具有可持续生产能力的农业生产区域。符合无公害农产品产地环境标准。具体地说就是,产地最好集中连片,具备一定的生产规模,产地区域范围明确,产品相对稳定;产地区域范围内、灌溉水上游、产地上风向,均没有对于产地构成威胁的污染源;另外,应尽 Currently, the main types of harmful products that affect the quality and safety of cucumber products are industrial “three wastes” pollution, pesticide residue pollution and accumulated nitrate pollution. Therefore, pollution-free cucumber cultivation will start from solving these three issues. First, the choice of pollution-free cucumber production base pollution-free cucumber production base selection of the basic principles are: good ecological conditions, far from pollution sources, and have sustainable production capacity of agricultural production areas. Meet the environmental standards of origin of pollution-free agricultural products. Specifically, the origin is preferably contiguous and contiguous, with a certain scale of production. The scope of the producing areas is clear and the products are relatively stable. There is no source of pollution that threatens the producing areas upstream of the irrigation area or upstream of the producing areas in the producing area. In addition, Should do it
