摘要:近年来多方面反应我国无人植保机防效不好的现状涉及到常用农药商品制剂在低倍稀释下的稳定性问题,为了进一步探究不同农药商品制剂低倍稀释乳液的稳定性,我们利用国标规定的关于农药的稳定性、挥发率和悬浮率的测定方法,对46种农药商品制剂分别在6.25倍、12.5倍、25倍、50倍、100倍和200倍的低倍稀释下进行了测定,结果表明,我国多数常用农药商品制剂在低倍稀释下都存在稳定性较差且挥发率和悬浮率都达不到国家标准的问题,反映了我国大多数常用农药制剂都不适合用于无人机作业,要想无人机得到更好的发展,需要研制出更多适合于无人机作业的药剂。37274 毕业论文关键词:无人植保机;农药商品;低倍稀释;不适合
The stability of pesticide products preparations in low dilution
Abstract: In recent years, the feedback on the effect of controlling pest and diseases by UAV in china is not very good, which involves the problem of stability of the conventional pesticides products in low dilution. In order to explore this problem further, we use the national standard on detection method to measure the stability, volatility and suspension percentage of 46 kinds of common pesticide products in 6.25, 12.5, 25, 50, 100 and 200 dilution. The results show that common pesticide products in our country have problems in stability, volatility and the suspension percentage but the suspension percentage, which reflects that most of pesticide products in our country is not fit to UAV, if we want UAV have good development in our country, more and more pesticide products fit to UAV must be researched out.
