1控制农药的污染蔬菜残留农药有机磷能引起神经功能紊乱,出现一系列神经毒性表现,重者中毒死亡。但在目前的条件下,无公害蔬菜的生产还离不开化学农药,因此在使用过程中,必须遵守“严格、准确、适量”的原则。1.1严格选择农药品种无公害蔬菜生产使用农药应有严格筛选,优先使用生物农药,有选择地使用高效、低毒、低残留的化学农药。蔬菜体内农药残留量与最后一次施药距采收时间的长短关系密切。间隔期短,则农药残留量多,
1 Control of pesticide contamination Vegetable residues Pesticide organic phosphorus can cause neurological disorders, a series of neurotoxicity, severe poisoning death. However, under the current conditions, the production of pollution-free vegetables can not be separated from chemical pesticides, so the principle of “strict, accurate and proper” must be observed during the use. 1.1 Strict selection of pesticides Varieties of pollution-free vegetable production and use of pesticides should be strictly screened, give priority to the use of biological pesticides, the selective use of high efficiency, low toxicity, low residual chemical pesticides. The amount of pesticide residues in vegetables is closely related to the length of the harvesting time of the last application. Short intervals, the pesticide residues and more,
