我国农业耕地面积14.32亿亩,复种指数1.64,全国播种面积达23.46亿亩(1999年,“中国农业统计资料”)。据业内人士介绍,我国化学防治面积达40多亿亩次,化学除草面积7亿亩次,并以每年3000～4000万亩增长。据农业部门统计,通过化学防治病虫草鼠害,每年减少农产品的损失功不可灭,如粮食减损5000万吨、棉花150万吨、蔬菜1500万吨、果品600万吨,以致使农业减少经济损失达到800亿元左右。根据估算,每使用1元农药可使农业获到8～16元,可见农药为保证农产品丰收和增加农民收入起着重要作用。
China’s agricultural arable land area of 1.322 billion mu, multiple cropping index of 1.64, the national sown area of 23460000 acres (1999, “China’s agricultural statistics”). According to insiders, the area of chemical prevention and control in our country amounts to more than 4 billion mu and the area of chemical weed control is 700 million mu. The annual increase is from 3000 to 40 million mu. According to the statistics of the agricultural sector, the loss of peasants, insects, pests, weeds and rodent pests can not be extinguished by reducing the loss of agricultural products through chemical prevention and control of pests, diseases and rodent pests. For example, 50 million tons of grain are damaged, 1.5 million tons of cotton, 15 million tons of vegetables and 6 million tons of fruits. Reaching 80 billion yuan. According to estimates, for every 1 yuan of pesticide use, agriculture can get 8 to 16 yuan, showing that pesticides play an important role in ensuring the harvest of agricultural products and increasing the income of farmers.
