5种矮化中间砧对瑞雪苹果叶片矿质营养的影响
Effects of five dwarfing interstocks on the mineral nutrition of'Ruixue'apple leaves
摘要
Abstract
Using'Qingzhen 1'as the rootstock and'M9T337','JM7','SH38','SC1',and'G935'as dwarfing interstocks respectively,'Ruixue'apples were grafted to explore the effects of the five dwarfing interstocks on the mineral nutrition of'Ruixue'leaves.The contents of macro-elements N,P,K,medium-elements Ca,Mg and trace elements Cu,Fe,Mn,Zn,B in the leaves were analyzed to evaluate the absorption characteristics of the five interstocks for the mineral nutrition of'Ruixue'leaves.The results showed that the contents of N,P,K,Ca,Mg,etc.of'Ruixue'with'JM7'as the interstock were significantly higher than those with other interstocks,and the B content of'Ruixue'with'SH38'as the interstock was the highest.Correlation analysis showed that there were significant positive correlations among elements such as N,P,Mg,Cu,Mn,B,especially the correlations between Mg and Mn(r=0.884)and between Cu and B(r=0.676)were obvious,while the correlations between Ca,Fe and other elements were weak.In conclusion,using'JM7'as the interstock was beneficial to improving the absorption of mineral nutrients by'Ruixue',and using'SH38'as the interstock was beneficial to improving B nutrition.This study provides a theoretical basis for the selection of'Ruixue'rootstocks and scientific fertilization.关键词
