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。

The experiment was carried out from 2007 -2008 on NJC19 peach trees by long-shoot pruning. The
Abstract:
effect of studying on tree growth and fruit quality with long-shoot pruning showed that the leaf area increased
about % and 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-shoot pruning". Both the Soluble solid content and the
titratable acid content increased. In addition, the fruit exterior quality was improving by long-shoot pruning.
