无公害水稻生产的农药和氮肥使用技术及其安全性

Research on the Application Techniques of Pesticide and Nitrogen in the Non-polluted Production Rice

结合安徽无公害水稻生产的实际 ,使用允许在无公害水稻生产中应用的部分农药品种进行病虫害防治 ,能有效地控制病虫危害。虽然有些农药使用的次数和使用量有所突破 ,但检测结果仍未检出农药残留。另外 ,对水稻后期增施一定量氮肥试验 ,也未检测出亚硝酸盐。

This experiment in the practice of non-polluted rice production was conducted. Some of the pesticides were used in order to control the damages caused by diseases and insects, but there are no pesticide residues in rice. In addition, in the experiment of the use of nitrogenous fertilizer in the later period of rice, NO - 2 can not be found.
