A Study on the Content of N,P,K in the Leaves and Fruit of Spur type Apple

doi:10.3321/j.issn:1000-7091.1997.03.024

Abstract

Abstract: The N,P,K and crude protein content in the leaves and fruits of spur type and common type apple were determined periodically.The results indicated that the contents of K,P and N reduced with increasing of the leaf age and development of the fruit.The analytical data of the contents of N,P,K and crude protein in the leaves and fruits of spur type and standard type apple were first obtained in the test.The statistical results showed that the contents of the elements in spur type were all higher than that in common type apple,and their difference was quit significant.

Key words: Spur type apple, Leaf, Fruit, Nitrogen, Phosphorus, Kalium, Crude protein
