| 摘 要： | 采用盆栽试验,研究了2种含钾土壤条件下不同有机酸对茄子产量和生长发育的影响。结果表明:通过叶面喷施有机酸可提高茄子单果重,改善植株的生长发育状况。其中,有机酸钾、甲酸、柠檬酸、乙酰丙酸与对照之间有显著差异;高钾土壤高于低钾土壤产量,且差异显著。有机酸的增产效果依次为有机酸钾>甲酸>柠檬酸>乙酰丙酸>草酸>丙酸>乙酸。

| Abstract: | By applying pot experiment,the effects of different organic acids on the growth and the yields of eggplants were studied in two kinds of soil of different potassium contents.The results showed that organic acids could improve single fruit weight and agricultural characters of eggplants by foliage dressing.There were significant differences between the experiment group and control group in potassium organo-carboxylate,formic acid,citric acid and acetylpropionic acid.The yield in soil of high potassium content was greater than that in soil of low potassium content with significant difference.According to the analysis of the effect of organic acid on eggplant yield,yield increase efficacy of organic acid was ranked in a descending order as follows: potassium organo-carboxylate>formic acid>citric acid>livulinic acid>oxalic acid>propionic acid>acetic acid. |
