就林木营养遗传研究进行综合评述,包括林木基因型对施肥反应的遗传差异、林木性状的遗传表达与营养环境、林木营养的遗传控制和变异机制等。鉴于我国现有林地和潜在造林地肥力普遍偏低,土壤缺氮少磷严重,在我国主要用材树种的现有育种程序中必须考虑营养性状的遗传改良。
A comprehensive review on the nutrition and genetic studies of forest trees was conducted, including the genetic differences of response to fertilization, the genetic expression and nutritional environment of forest traits, the genetic control and mutation mechanism of forest nutrition. In view of the generally low fertility of forest land and potential afforestation land in our country and the serious shortage of nitrogen and phosphorus in soil, the genetic improvement of nutritional traits must be considered in the existing breeding programs of the main timber species in our country.
