在当前栗树栽培中,存在着实生栗树结果晚、产量低、变异性大和抗性弱等问题。特别是在我省东部和北部栗树枯梢等冻害较为严重。鉴于栗树嫁接苗能提前结果,并能保持母树的优良特性。因此,利用山区丰富的柞树资源为砧木嫁接栗树,不但可以节省苗木,而且能提前结果,还可提高抗寒力。所以,柞、栗嫁接是我省山区发展栗树的一条途径。我所于1974年开始,先后在本溪县草河口镇草河口大队和桓仁县向阳公社北岔大队 In the current chestnut cultivation, there are some problems such as the real chestnut yield is late, the yield is low, the variability is large and the resistance is weak. Especially in the eastern and northern parts of the chestnut shrubs and other frost damage is more serious. In view of chestnut grafted seedlings can advance the results, and can maintain the excellent characteristics of the mother tree. Therefore, the use of rich oak resources in mountain areas as rootstocks grafted chestnut trees, not only can save seedlings, but also in advance results, but also improve the cold hardiness. Therefore, oak, chestnut grafting is the development of chestnut trees in our province a way. I started in 1974, successively in Caohekou Township, Benxi County, Grassland and Huanren County Xiangyang commune Beifu Brigade
