无公害水稻高产栽培配套技术研究

Study on conveyance technologies of highyield cultivation without environmental pollution of rice

试验示范结果表明水稻无公害生产示范区实施作物健壮栽培、施用农家肥和水稻专用生物有机肥 ,应用无公害农药和农业措施 ,必要时限量使用高效、低毒和低残留化学农药防治病虫草等高产栽培配套技术 ,可减少种子、化肥和农药施用量 ,稻谷中农药和重金属等有毒害物质残留量低于绿色食品卫生指标 ,并增加田间蜘蛛等天敌 ,降低生产成本 2 85元 /hm2 ,增加稻谷收入 16 6 7元 /hm2 。

The used quantities of seeds, fertilizers and pesticides were decreased, the production cost was reduced by 285 yuan and the incomes from paddy were increased by 1667 yuan per hectare in the demonstrative area of production without environmental pollution of rice by a series of conveyance technologies of gymnastic cultivation of rice, using farm manure, organic manure for a special purpose of rice, applying pesticides without environmental pollution and agricultural methods, using chemical pesticides of high efficiency, low toxicity and lower residue of limited quantity against diseases, insect pests and weeds at necessary time. The residues of poisonous pesticides, heavy metal and other indexes in rice are lower than the health targets of green food. Their natural enemies such as spiders and others should be increased in paddy fields.
