Almond Leaf Mineral and Trace Element Content Changes and Correlation Analysis at Different Growth Stages
摘要
Abstract
Objective]Almond Leaf Mineral and Trace Element Content Changes and Correlation Analy-sis at Different Growth Stages.This paper's goal is to provide a theoretical basis for nutrition diagnosis and ra-tional fertilization during the different growth stages.[Method]The almond 'Yerqiang'varieties were taken as test materials and the content changes of N,P,K,B,Fe,Mn,Zn,Cu,Mg,and Ca elements in the leaves during the growth periods as the study subjects.[Result]The results showed that during the leaf development, the content of mineral elements N,P,K,Mn,Zn and Cu showed a downward trend and meanwhile Fe,Mg, Ca demonstrated a rising trend,and the B element content was in a zigzag trend.At the same time,there were correlations between the various elements of the growth period.Three groups in the leaf expansion period,sev-en groups in expanding period,four groups during the period of hard core and six groups in the mature period, their correlation of mineral elements in different growth stages was different.[Conclusion]Therefore,accord-ing to the mineral elements at different growth stages of almond,only the rational balance of fertilization can meet the nutritional needs of the tree body.关键词
