摘要
2005-2007年对因白蚁为害、生长衰老和管理粗放而造成产量下降的香榧(Torreya grandis cv.Merrillii)古树分别采取整枝修剪、白蚁防治、培土及施肥等复壮措施。结果表明,各处理香榧古树枝叶性状、结果性能、株产量均有明显提高,与对照古树表现出极显著性差异,主要表现在新梢数量、粗度,叶片长度和宽度以及鲜质量和干物质质量的增加,树势旺盛,复壮处理单株香榧果实产量均增长1倍或1倍以上,而对照单株产量则继续下降。
From 2005 to 2007, investigation showed ancient Torreya grandis cv. Merrillii trees with lower yield caused by termites, senile and extensive management. Measurements such as pruning, control of termites, earth up and fertilization were taken for rejuvenation. The result showed that new shoot quantity and diameter, length and width of leaf, quantity of fresh and dry matter increased compared with the control.
