摘要
为了了解砂糖橘果实生长发育期养分累积吸收的规律以期进行柑橘的养分综合管理,在高产果园选取4 年和8 年2 种树龄的柑橘树,对2种树龄果实中的氮、磷、钾、钙、镁各矿质营养元素的累积吸收量进行了研究.结果表明,在果实生长发育期,4 年树和 8 年树单果中各矿质营养元素累积吸收量的变化趋势一致,其大小顺序为氮＞钾＞钙＞磷＞镁,其中,4年树单果中氮、磷、钾的累积吸收量均值显著大于8年树,而钙、镁的累积吸收量则是8年树显著大于4年树.表明钙养分主要累积在果皮中,镁养分主要累积在果肉中.
Abstract
In order to understand the nutrients accumulation of sugar orange fruit during it development to carry out the nutrients comprehen-sive management of the fruit tree,mineral element of N,P,K,Ca,Mg uptake were measured at different developing stage for both 4 and 8 years old sugar orange fruit tree.The results showed that nutrients absorption by individual fruit was in order of N＞K＞Ca＞P＞Mg for both of four-year and eight-year old tree in whole fruit developing stages.The average uptake of N,P,K in four-year old tree was significantly higher than those of eight-year old one,but the average uptake of Ca,Mg in eight-year old tree was significantly higher than those of four-year old one.The result also showed that Ca was mainly accumulated in peel and Mg in pulp of the fruit.
