摘要
对浙江东阳市30年来香榧早实丰产栽培生产实践的调查表明:香榧可以通过多种途径实现早实丰产。当地已经形成5种模式:野生砧就地嫁接模式,野生砧异地嫁接模式,实生大苗多头嫁接模式,嫁接大苗工程造林模式和嫁接壮苗加强管理模式;提出了获得早实丰产的9项技术措施:坚持适地适树;选用早实品种;坚持壮苗浅栽;摘顶修枝整形;间种抚育管理;合理正确施肥;年年深挖促根;及时防治病虫;适时调控结实。该市现已建成约75 hm2早实丰产香榧试验园,年产榧蒲103 t,产生高达1 500多万元的经济效益。
According to the investigation of 30-year＇ s practices of Chinese torreya （ Torreya grandis） early-ripening and high-yielding cultivation in Dongyang, Zhejiang Province, it was showed that the early-ripening and high-yielding of Chinese torreya could be reached by various measures. Five local patterns were as follows ： grafting on the wild stock at the spot;grafting on the wild stock after planting on another spot;grafting on seedlings;engineering afforestation with grafted young stocks ; and enhancing the management of vigorous stocks. Nine technical measures for earlyripening and high-yielding production were put forward, i. e. matching species with the site;selecting early-ripening species ; shallow planting the vigorous stocks ; top removing, pruning; interplanting and tending ; properly fertilizing; deep digging and promoting root growth ; pest controlling; and fruiting regulating. A 75 hm^2 of early-ripening and fastgrowing Chinese torreya experimental plot was established which produced 103 tonnes of seed annually and 15 million RMB yuan of economic benefits had been achieved.
