本项调控工程分两步:1984—1986年在山一村106ha农田开展病虫害综合防治试验示范;1987—1989年将试验成果应用于生产。试验研究取得了明显的经济效益、生态效益和社会效益:农药用量比1983年前减少80.6％,稻谷中农药残留不超标(原有机氯农药666残留超标率31.6％);害虫天敌稻田蜘蛛增加83.3—180.0％,稻虱多索线虫增加2倍;防治农药成本减少53.7％。并制定了《山一村农田农药污染防治技术规程》,其主要内容有:开展病虫害“二查二定”,达到防治指标时用药;制定病虫害防治策略,在防治适期内用药;推广高效低残留农药,遵守农药安全间隔期;推广抗性良种,适施N肥,增施P、K肥;保护利用天敌,发挥天敌自然抑制作用。
This regulation and control project is divided into two steps: From 1986 to 1986, demonstration experiments on pest and disease control were carried out on 106ha farmland in Shanyi Village. From 1987 to 1989, the test results were applied to production. The experimental study has achieved obvious economic, ecological and social benefits: the amount of pesticides decreased by 80.6% compared with that before 1983, the pesticide residues in rice did not exceed the standard (the excess of the original organochlorine pesticides 666 was exceeded by 31.6%), and the insect pest spider increased 83.3 -180.0%, Doxorubicin increased 2-fold; the cost of pesticide control decreased by 53.7%. And developed a “mountain village farmland pesticide pollution prevention and control of technical regulations,” its main contents are: to carry out “pests and diseases” two investigation and two set "to reach the target of prevention and treatment of drugs; development of pest and disease control strategies, medication in the prevention and treatment of period; promotion of high efficiency Residual pesticides, pesticide safety interval to follow; promotion of resistant varieties, suitable for N fertilizer, increase P, K fertilizer; protection and use of natural enemies, natural enemies play a natural inhibitory effect.
