摘要

由于芽、花、果实和果实的脱落，牛油果贸易中的总营养损失相对较小。只有25.8公斤N, 3.7公斤P和31.0 kg.haK在脱落的器官中发现。其中铁的损失是其他微量元素的7 ~ 50倍(1.40 kg.ha.I)。除磷外，其他营养物质与以前或将来的产量没有关系。花中磷含量降低后，次年冬季产量增加。作为影响牛油果产量的一个因素，少量的营养损失似乎并不重要。

MINERAL LOSSES OF AVOCADO TREE RESUL TING FROM ABSCISSION OF FLOWERS, FRUITLETS AND FRUITS

The total nutritionalloss in an avocado trae due te abscission of buds, flowers, fruiUets and fruits is relatively small. Only 25.8 kg.ha.1 N, 3.7 kg.ha.1 P and 31.0 kg.ha.1 K are found in the abscissed organs. Among the microelements Fe is lost 7 to 50 times more than the other microelements (1.40 kg.ha.I). No relationship was found between the nutrients and the previous or future yield except for phosphorous. Decrease in P level in the flowers was followed by an increase in yield the following winter. The small nutritionalloss seems to be of minor importance as a factor in avocado productivity.
