- 摘要：叶枯灵简称BHD,化学名称为2-苯甲酰(酉井)叉-1,3二噻茂烷(2-Benhzoyl-hydrazono-1,3-dithiolane),分子式为C10H10N2OS2,分子量为238,是由重庆农药厂农药研究所研制成功的一种新型有机硫杀菌剂.它对于亚洲国家防治水稻细菌性维管束病害--白叶枯病具有显著的预防和治疗效果.由于该药迄今国外尚无商品化生产,为预测和评价其对稻田生态环境的安全性,避免污染并合理使用,我们进行了下
- Abstract：The Yekuling detention and degradation in the environment of rice fields were studied. The photolysis rate of Yekuling in ultraviolet light was greater than that in sunlight. The degradation of Yekuling in the field was faster than that in the laboratory. The hydrolysis and microbial decomposition in water played a major role in Yekuling degradation. Yekuling was mainly remained at the surface layer of soils because of the strong adsorption.A significant correlation was revealed between the organic content in soil and the rate of adsorption. The rate of adsorption was also influenced by the type of soils and the amount of clay in soil. The degradation pattern of Yekuling in the rice field can be expressed as y = ae-bt.
