The nutrient absorption in fruits were lower than other fruits,especially,the amount of phosphorus and calcium in fruits were only one eighth of Satsuma mandarin.It is one of the nutrient physiology characteristic in Chinese bayberry that the amount of absorbed phosphorus in whole tree,and phosphorus,calcium in fruit are rather lower.

幼年树和成年树P吸收量分别为0.37 kg和0.9 kg，占全量的2.7%和2.3%，其吸收量和吸收比例均较低；果实养分吸收量与其它果树相比，相对较低，尤其是P2O5和CaO的吸收仅为温州蜜柑类的1/8，认为杨梅树体P、果实P和Ca吸收量低是杨梅营养生理的特性之一。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
