Abstract: There are great effects of pesticide residues on rice quality and people's health. Through the introduction of an enzyme reagent, a study was carried out to explore the effects of using time and dosage of the reagent on pesticide residue in rice. The results showed that the suitable dosage of the enzyme reagent was 5 400~9 000 mL/hm2 and applied in 5 days before heading and after heading, could reduce the pesticide residue, different varieties had different suitable dosages.

Key words: enzyme preparation, pesticide residue, degradation, safety production

摘要： 农药残留影响稻米品质，直接影响人们的身体健康。通过引进一种酶制剂，研究了该试剂不同使用时期和使用量对稻米中农药残留的影响，以集成稻米的安全生产技术。结果表明，应用战氏生物转换酶制剂，在总用量为5 400 ~9 000 mL/hm2时，在水稻抽穗前5 d和齐穗后5 d各喷施叶面1次，可以收到较好的降低农残的效果。该酶制剂在德优4727、川优6203生产中适宜的使用量为5 400 mL/hm2以上，能实现未检出农残的效果；在宜香2115、F优498生产中适宜的使用量为9 000 mL/hm2时，才能达到未检出农残的效果。
