一种植物生长调节剂的合成及其对小麦促生长作用

摘要

2,4-potassium is a plant growth regulator. Using 2,4-dinitrochlorobenzene and potassium hydroxide as reactants,2,4-potassium was synthetized by alkali hydrolysis. And it was studied by a pot experiment of wheat on the 2,4-potassium which affects on height and root growth of wheat plant. The results showed that the synthesis method has simple operation,fast reaction speed,the synthesis yield of 91.6%,moreover,a by-product of the reaction of potassium chloride can also be used as potassium absorbed by plants. The synthesized products of the study has obviously promoted wheat growth.%2，4-二硝基苯酚钾是一种植物生长调节剂.利用2，4-二硝基氯苯和氢氧化钾作为反应物，通过碱水解方法合成了2，4-二硝基苯酚钾.通过小麦盆栽实验研究了2，4-二硝基苯酚钾对促进小麦株高及根系生长的影响.结果表明：该合成方法操作简单，反应速度快，合成产率达91．6％，反应副产物氯化钾也可以作为钾盐被植物吸收利用；利用该法合成的产物有明显促进小麦生长作用.
