四年前,江西省吉安县农户全年水稻病虫防治成本大约每亩55元,最近笔者调查发现:近两年该县农户仅晚稻一季的防治成本就达每亩80多元,有的竟超过100元,首次出现农药成本超过化肥投入,这是一个值得相关部门关注的问题。农药用量和成本的剧增,农民种植效益下降不说;大量施用的农药对地下水、土壤和环境的污染不可轻视。下面介绍一些降低农药用量和成本的方法,希望能对农户有所帮助。
Four years ago, Ji’an County, Jiangxi Province, peasant households throughout the year about 55 yuan per mu pest control costs, the recent survey found: the past two years, the county farmers only one season of late rice prevention and control costs reached 80 yuan per mu, and some actually exceeded 100 yuan, the first cost of pesticides than fertilizer investment, which is worth the concern of the relevant departments. Pesticide consumption and cost increases sharply, farmers do not say the benefits of planting; large number of pesticides applied to groundwater, soil and environmental pollution can not be underestimated. Here are some ways to reduce the amount and cost of pesticides, hoping to help farmers.
