一种稻米生产中有机磷农药降解的试验研究

研究一种氨基酸有机肥对稻米生产中有机磷农药的降解效率。在水稻抽穗前5天以喷施较高剂量有机磷农药为对照,以联合喷施一种氨基酸有机肥为处理,分析稻米中农残的降解动态。结果表明,该氨基酸有机肥对三唑磷、毒死蜱、氧乐果、甲胺磷等有较好的降解作用,在15-30 d 降解效果较好,降解效率为11.2%-94.7%,对水胺硫磷降解效果不明显。该氨基酸有机肥能够有效促进稻米中有机磷农残降解,肥效合一,可应用于优质稻保优提质绿色高产高效生产。

Study on Degradation of Organophosphorus Pesticides in Rice Production

The degradation efficiency of an amino acid organic fertilizer on organophosphorus pesticides in rice production was studied. The degradation dynamics of pesticide residues in rice was analyzed by spraying high-dose organophosphorus pesticides as control and combined spraying an amino acid organic fertilizer as treatment 5 days before heading. The results showed that the amino acid organic fertilizer had degradation effect on triazophos, chlorpyrifos, omethoate and methamidophos, and the degradation rate was from 11.2% to 94.7%, the degradation effect was better in 15-30 days, and the degradation effect of isocarbophos was not obvious. The amino acid organic fertilizer can effectively promote the degradation of organophosphorus pesticide residues in rice, it has combination of fertilizer and effect. It can be applied to the green, high-yield and high-efficiency production of high-quality rice.
