摘要
对苹果萌芽前根外营养 (P ,K ,Ca ,B)的吸收分配及与果实品质的关系进行了系统研究。结果表明 :萌芽前根外营养可明显提高长枝、短枝和幼果中的N、P、K含量。对提高果实品质效果明显 ,全红果率和优等级果率达 93 3%和 94 5 % ,比对照提高 1 5 1 %和 1 7 0 %。P、K可提高果形指数、全红果率和优等级果率。K。
The objective of this study was to investigate the absorption of element P,K,Ca and B and its effects on apple fruit quality The results showed that application of P,K,Ca and B before sprouting in the early spring could significantly increase the P and K content in shoots,spurs and young fruits And it could also improve the fruit quality,i e the rate of whole red and first-grade apple were 93 3% and 94 5%,respectively,which were 15 1% and 17 0% more than the control Besides,P and K could elevate fruit indexes (Longth/Diameter) and the rate of whole red and first-grade apples K and Ca increased the fruit hardness and soluble solid content
