- 摘要:
- 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。
- Abstract:
- Taking general type of peach ‘Chunyan’ and spur type ‘Super red spur’ as materials，the correlation between nitrogen，phosphorus，potassium content in leaves of peach and dwarf in different growing type peaches were studied，in order to provide reference basis for breeding of excellent dwarf cultivars and dwarf density planting pattern.The results showed that the nitrogen，phosphorus，potassium content in leaves of peach and dwarf had positive correlation.Nitrogen，phosphorus content in leaves of spur type peach and dwarf had significant positive correlation.The difference between potassium content in leaves of peach and dwarf was extremely significant.The nitrogen，phosphorus，potassium content in leaves of spur type peach were higher than the general type peach，and their difference reached extremely significant level.
