针对富阳市板栗生产上存在的问题,在广泛调查基础上,选用新登镇王村的1株早熟型板栗优株,进行嫁接繁殖、育苗造林试验,经5年的连续验证,该无性系具有早熟,早实、丰产、高产等优良特性,而且还具有抗干旱、耐瘠薄的能力。5年生平均株产3.85kg,合每公顷产板栗3225kg,超过了杭州市科委下达的丰产指标的4.3倍,特别是该板栗无性系果实在9月上旬提早成熟,从而提高商品的经济价值。通过对早熟型高产板栗栽培技术研究实践,形成了1个从良种选育、培育壮苗、合理修剪、生长素应用和营林管理一套丰产栽培技术体系,这将对今后板栗生产的发展有一定的促进作用。
Aiming at the existing problems of chestnut production in Fuyang City, based on extensive investigation, 1 precocious chestnut superior strain of Xindeng Town Wangcun was selected for grafting, breeding and nursery afforestation. After 5 years of continuous verification, Early maturity, early seed, high yield, high yield and other excellent features, but also has the ability to resist drought and barren. The 5-year average annual yield of 3.85kg, per hectare yield 3225kg chestnut, Hangzhou Science and Technology Commission exceeded the high yield index of 4.3 times, especially the chestnut clones early premature in September to improve the economic value of the commodity. Through the research and practice of precocious high-yielding chestnut cultivation techniques, a high-yielding cultivation technique system has been established which includes selecting and breeding elite seeds, cultivating strong seedlings, rational pruning, auxin application and silviculture management, which will have a great impact on the future development of chestnut production A certain role in promoting.
