摘　　要：在梨树上进行尿素、磷酸二氢钾、硼肥及其混合液的高浓度晚秋叶面喷施 ,对处理后休眠期枝条及翌年花序、叶片中相应矿质成分含量进行分析 ,结果表明晚秋叶施高浓度肥料均能显著增加梨树休眠期枝条中相应矿质成分的含量 。Treatments on pear trees were conducted with high concentration of urea, potassium bi hydrogen phosphate, boronic acid and their mixtures. Effects of the treatments on the content of corresponding mineral elements in annial branches dormancy, inflorescences and leaves in the following year, were studied systematically. The results showed that late autumn foliar application of high concentration fertilizers increased the content of corresponding mineral elements in annial branches during the dormant period and also accelerated their storage and transportation.
