辽宁省是我国板栗经济栽培区的北界,在生产上有中国板栗(Castanea Mollissima Blume)和丹东栗(Castanea dandonensis Lieolishe)两个种。中国板栗比丹东栗品质好,含糖份多,涩皮易剥,但实生繁殖较丹东栗结果晚,产量低。我省现有栗树约1,500万株(丹东栗占86％),其中结果树约300万株,年产栗子600多万斤。当前生产中的主要问题是结果晚、产量低、品质差、经济收益少。针对这些问题,谈谈我们的意见。
Liaoning Province is the northern border of China’s chestnut cultivation area. There are two species of Castanea Mollissima Blume and Castanea dandonensis Lieolishe in China. Chinese chestnut than Dandong chestnut good quality, more sugar, astringent skin easy to peel, but the actual reproduction of Dandong chestnut results late, low yield. The province has about 15 million chestnut trees (Dandong chestnut accounted for 86%), of which about 3000000 trees, annual output of chestnuts more than 600 kilograms. The main problems in current production are late results, low yields, poor quality and low economic returns. In response to these questions, talk about our opinions.
