以普通型桃“春艳”和短枝型桃“超红短枝”为试材,研究了2种类型桃叶片中氮、磷、钾含量与树体矮化的关系,以期为桃树优良短枝型品种的选育和高效矮化密植提供参考依据。结果表明:桃叶片中氮、磷、钾含量与树体矮化程度呈正相关。短枝型桃叶片中氮、磷含量与树体矮化程度呈显著正相关,钾含量与树体矮化程度间的差异达到了极显著水平。短枝型桃叶片中氮、磷、钾含量在整个年周期变化中高于普通型,达极显著差异水平。
The relationship between nitrogen, phosphorus and potassium contents and tree dwarf in two types of peach leaves was studied with common peach “Chunyan ” and spur type peach "super red spur This study provides references for the breeding and efficient dwarf densification of fine spur varieties of peach. The results showed that the contents of nitrogen, phosphorus and potassium in peach leaf were positively correlated with the degree of dwarfing. The content of nitrogen and phosphorus in spruce-leaf peach had a significant positive correlation with the degree of dwarfing of the tree, and the difference between the content of potassium and the dwarfing of tree reached the extremely significant level. The content of nitrogen, phosphorus and potassium of spruce-leaved peach leaves was higher than that of the common type in the whole year cycle, reaching the extremely significant difference level.
