摘要
以17年生早实核桃品种中林1号、辽宁1号和薄壳香为试材,研究了早实核桃叶片主要营养元素的代谢规律。结果表明:1)核桃叶片内N,P,K含量总体是呈由高到低的变化趋势。2)Ca元素的含量在整个生长期中呈逐渐上升的趋势;Mg元素含量随着生长期的推进而呈上下波动趋势;Zn的含量在整个生理期呈下降趋势。
Taking precocious walnut Zhonglin 1, Liaoning 1 and Bokexiang as materials, metabolic rule on main nutrient ele- ments of precocious walnut leaves were studied. The results showed that contents of N, P and K showed decreasing tendency in the whole season; the content of Ca increased gradually and that of Zn was opposite ; the content of Mg was higher in June 14 and early August than any other times.
