摘要： 选用2种季铵盐化合物（山梨酰胺季铵盐SLJA和肉桂酰胺季铵盐RGJA），研究其抑制真菌、促进种子萌发及提高田间作物生长的效果，研究发现:两种化合物在16 mg·mL-1的浓度下对供试真菌的抑制率可达70%以上，萝卜种子的萌发率在16%，均高于空白对照组(CK)，对萝卜幼苗根长和茎高上均有较大程度的促进作用，其对幼苗叶片中的蛋白质含量、叶绿素含量及氨基酸含量上没有达到显著的差异，对田间柳树和国槐的研究中发现，采取灌根的方式比叶面喷洒增长率高，其中SLJA-2对柳树灌根后苗高增长促进率达2826%，树茎增长促进率达588%，RGJA-2对柳树灌根后苗高增长促进率达4461%，树茎增长促进率达4250%。

Abstract: In this paper, two quaternary ammonium compounds (SLJA and RGJA) were selected to study their effects on inhibiting fungi, promoting seed germination and improving crop growth in the field. It was found that the inhibition rate of the two compounds on the tested fungi was over 70% at the concentration of 16 mg·mL-1, and the germination rate of radish seeds was 16%, was higher than CK, which promoted the root length and stem height of radish seedlings to a greater extent. There was no significant difference in protein content, chlorophyll content and amino acid content in leaves of radish seedlings. In the field study of Salix babylonica and Sophora japonica, it was found that the growth rate of root irrigation was higher than that of leaf spraying, and slja-2 promoted the growth rate of willow seedling height by 2826%. The growth rate of the stem was 588%, rgja-2 was 4461% and 4250% respectively.
