一、氮素对果树生长结实的作用氮(N)化合物在树体总干重中占较小的一部分,一株18年生的玉霰苹果,氮只占0.34%,但它是生理上重要化合物的组分,如核酸、蛋白质、氨基酸、酶、辅酶、叶绿素、激素、多种维生素中都含有氮,因此,它直接影响果树的代谢和生长发育.
Nitrogen on the growth and fruiting of fruit trees Nitrogen (N) compounds account for a relatively small part of the total dry weight of trees. An 18-year-old jade-apple is only 0.34% nitrogen, but it is a physiologically important compound The components, such as nucleic acids, proteins, amino acids, enzymes, coenzymes, chlorophyll, hormones, vitamins contain nitrogen, therefore, it directly affects the metabolism and growth of fruit trees.
