烯效唑是一种广谱、高效的植物生长调节剂,受现有剂型影响,在土壤中的运移易受阻,导致大部分药物不能扩散到植物根系,从而降低其利用率.基于以上问题,本文利用花生油作为油相制备了烯效唑水包油型乳剂,通过构建横向传输模型土柱,在乳液分散方式、乳化剂类型、乳液浓度、乳液流速以及横向传输距离等方面考察了花生油基烯效唑乳液在土柱中的横向传输能力,并与烯效唑的水分散剂比较,表明烯效唑乳剂较水分散剂具有更强的横向传输能力.当烯效唑乳液浓度为 500 mg·L-1,进样流速为 1.23 mL·min-1,横向传输距离为 40 cm 时具有较好的横向传输能力.本文的研究结果将为烯效唑的绿色高效使用提供参考.
Study on preparation and transversal transport of peanut oil-based uniconazole emulsion in soil
Uniconazole,as a broad-spectrum and efficient plant growth regulator,is easily hindered in soil transport,resulting in most drugs not being able to diffuse to plant roots and reducing their utilization efficiency.Based on the above problems,in this paper,pea-nut oil was used as the oil phase to prepare uniconazole oil in water emulsion.By constructing a transverse transport model soil column,the transverse transport capacity of the peanut oil-based uniconazole lotion in the soil column was investigated in terms of the dispersion mode of the lotion,the type of emulsifier,the concentration of the lotion,the flow rate of the lotion,and the transverse transport dis-tance.Compared with the water dispersion formulation of uniconazole,the uniconazole lotion has a stronger transverse transport capaci-ty than the water dispersant.When the concentration of uniconazole lotion is 500 mg·L-1,the flow rate into the soil column is 1.23 mL·min-1,and the transverse transmission distance is 40 cm,it has good transverse transmission capacity.The research results of this ar-ticle provide a reference for the green and efficient use of uniconazole.
