为了了解球果生长发育和成熟时一系列生理生化特性和变化规律,对粗枝云杉球果内9种营养元素的季节动态变化进行了研究,研究表明:随着季节的变化,粗枝云杉球果内营养元素含量的大小顺序大致相同,即K>N>P>Mg>Ca>Fe>Zn>Mn>Cu,而变异系数大小顺序为:N(C.V%=50.65)>Ca(C.V%=25.24)>Fe(C.V%=23.08)>P(C.V%=21.19)>Cu(C.V%=14.75)>Mg(C.V%=12.36)>Mn(C.V%=11.04)>K(C.V%=9.50)>Zn(C.V%=7.79)。粗枝云杉球果中营养元素间的相关性为:N和P,Mg和Zn均呈显著正相关,P和K、Mg、Cu还有Zn均呈显著正相关,K和Mg、Cu还有Zn呈显著正相关。
In order to understand a series of physiological and biochemical characteristics and changes during the growth, development and maturation of cones, the seasonal dynamics of nine nutrient elements in the spruce coniferous fruit were studied. The results show that with the seasonal changes, The order of the nutrient elements in the cotyledons was similar, ie K> N> P> Mg> Ca> Fe> Zn> Mn> Cu, while the order of variation coefficient was N (CV% = 50.65)> Ca % = 25.24> Fe CV% = 21.08> P CV% = 21.19> Cu%> 14.75> Mg% CV = 9.50)> Zn (CV% = 7.79). The correlations among nutrient elements in the spruce cones were as follows: N and P, Mg and Zn were positively correlated, P and K, Mg, Cu and Zn were significantly positive correlation, K and Mg, Cu also There was a significant positive correlation between Zn.
