喷施翠康生力液对早熟马铃薯品种克新4号产量和淀粉含量的影响

Effects on Yield And Starch Content By Applying "Cui Kang Sheng Li Ye" On Leaves Of Early Potatoes cv. Kexin No.4

研究了四种常用叶面肥对马铃薯产量和品质的影响。结果表明,不同种类的叶面肥和同一种叶面肥的不同使用浓度对马铃薯产量和品质的影响存在显著差异。1)喷施“翠康生力液”和“肥力高”能明显提高产量:喷施“膨大素”和“植物动力2003”对产量影响不大。“肥力高”虽然产量提高比较明显但成本较高;2)喷施500倍液“翠康生力液”可提高产量45．2％,淀粉含量提高2．4％,是降低成本,提高产量,增加经济效益有效途径之一。

The effects of four foliar fertilizations on the yield and quality of potato are researched in this paper. The results showed that the effects of the different kinds and treatment concentrations of foliar fertilization on the yield and quality of potato are significantly different. 1） With the using “CUI Kang Sheng Li Ye” and “Fei Ligao”, yields of potato increase obviously; the yields before using “Peng Dasu” and “Zhi wudongli 2003” do not vary evidently. With the using of “Fei Ligao”, the yields were enhanced markedly, the costs were high; 2） “Cui Kang Sheng Li Ye” in 500 times solution could increase yield and content of potato starch were 45.2% and 2.4% respectively. It is an available way to enhance yield and decrease cost and increase economy benefit.
