| 摘 要： | 连续2年对NJC19黄桃进行长枝修剪试验,对树体生长和果实品质进行测定分析.结果表明,与传统的短枝修剪技术相比,经过长枝修剪后的树体叶面积增大,净光合速率提高;徒长枝比例降低,优质果枝率增加;一年生枝条的可溶性糖和淀粉含量均提高,树体营养状况得到改善;果实的可溶性固形物含量和可滴定酸含量均得到提高,果实着色更加均匀.

| Abstract: | The experiment was carried out from 2007 ~2008 on NJC19 yellow peach trees by long pruning. The effect of studying on tree growth and fruit quality with long pruning showed that the leaf area increased about 15.5% and the net photosynthetic rate improved. The proportion of water sprout and developmental branch decreased, and the number of top quality branch increased. The contents of soluble sugar and soluble starch were higher than those with traditional "short pruning". Both the Soluble solid content and the titratable acid content increased. In addition, long pruning significantly improved the fruit exterior qualities. |
