摘要

为了了解白三叶青贮饲料中不同残留农药的降解情况及其对青贮饲料品质的影响,在白三叶中添加了三种不同浓度的果园常用农药,并发酵90天。结果表明,不同浓度的氯氰菊酯及其毒性降解产物 3-苯氧基苯甲酸(3-PBA)在青贮后的降解率最高,均为 100%。戊唑醇和氯哒嗪的降解率分别为 72.47%-80.27%和 47.76%-64.82%,其中有毒降解产物 3,5,6-三氯-2-吡啶醇(TCP)含量增加了 0.0525-0.253 mg-kg-1。青贮后,β-氯氰菊酯和戊唑醇的残留量达到了安全标准。与对照组相比,处理过的样品中乳酸、乙酸和丙酸的含量有所增加。三种农药的浓度越高,青贮饲料中的乳酸含量越低(p

The degradation of residual pesticides and the quality of white clover silage are related to the types and initial concentrations of pesticides.

In order to understand the degradation of different residual pesticides of white clover silage and their influence on silage quality, three commonly used orchard pesticides with different concentrations were added to the white clover and fermented for 90 days. The results showed that the degradation rate of cypermethrin and its toxic degradation product 3-phenoxybenzoic acid (3-PBA) was the highest after silage, at different concentrations, both were 100%. The degradation rate of Tebuconazole and chloropyridine was 72.47-80.27% and 47.76-64.82%, of which 3,5,6-trichloro-2-pyridinol (TCP) content, poisonous toxic degradation product, increased 0.0525-0.253 mg·kg-1. The residues of beta-cypermethrin and tebuconazole had reached safety standards after silage. As compared with the control, the contents of lactic acid, acetic acid, and propionic acid increased in the treated samples. The higher concentrations of three pesticides all significantly reduced the lactic acid content of silage (p<0.05). Pesticides had different effects on the nutritional components of white clover silage. Conclusively, silage is a potential way to expand the utilization of covering plants in orchards.
