板栗是优良经济树种。我市栽培历史悠久,现有栗树500万株,多生长在山区丘陵与沟谷河滩等处。由于以往多为实生繁殖,管理粗放,常年产量只有50万斤上下,平均亩产不足10斤,结实潜力远未得到发挥。为此,我们于七十年代初便开始着手“改造低产板栗树”的试验,1981年又接受了山东省林业厅下达的“板栗良种选 Chestnut is an excellent economic tree species. City has a long history of cultivation, the existing 5 million chestnut trees, and more growth in the hills and valleys and other beaches. As in the past mostly real breeding, extensive management, perennial output of only 500,000 pounds, the average yield less than 10 pounds, the sturdy potential far from being played. For this reason, we started the experiment of “transforming low-yielding chestnut trees” in the early 1970s. In 1981, we accepted the “Chestnut Variety Selection” issued by the Forestry Department of Shandong Province.
