| 摘 要： | 通过使用不同浓度的磷酸二氢钾溶液进行加工型马铃薯叶面喷施,研究不同浓度的磷酸二氢钾叶面喷施对加工型马铃薯的生长效应。试验结果表明:随着磷酸二氢钾浓度的提高,马铃薯株高、茎粗、地上部干重和块茎粗淀粉、蛋白质、干物质、维生素C含量增加,产量显著增加,当磷酸二氢钾浓度提高到一定程度时产量开始下降,增产效果随浓度的提高呈抛物线型的变化趋势;磷酸二氢钾溶液叶面喷施马铃薯浓度为0.3%时,其产量最高,品质最佳。

| Abstract: | Various concentrations ofpotassium dihydrogen phosphate were studied for their effects on growth ofprocessing type potatoes when applied as foliage spray.The plant height,stem diameter,haulm dry weight,and starch,protein,dry matter and vitamin C contents of tubers were increased as increasing in potassium dihydrogen phosphate concentrations to a point,where they were decreased.The yield of tubers showed the same trend,and could be described by a parabolic curve.The best yield and quality were achieved when the potassium dihydrogen phosphate was at 0.3%. |
