摘要
在花年毛竹纯林进行1 a覆盖-1 a套种竹荪轮作等经营模式试验,研究毛竹林覆盖后套种竹荪轮作模式经济效益和生态修复作用。结果表明:(1)1 a覆盖-1 a套种竹荪轮作模式的2 a净收入达到18.0万元/hm^2,投入产出比达到1∶3.29,分别是传统单一经营模式、1 a覆盖-1 a自然培育经营模式的19.6倍和1.6倍。(2)毛竹林覆盖后套种竹荪轮作模式在高碳氮比(C/N)有机物覆盖的清理、林地土壤改良、林地地力培育等生态修复效果明显优于1 a覆盖-1 a自然培育经营模式,有效防止竹林地因覆盖而引发竹林衰退。毛竹林覆盖与套种竹荪轮作模式是毛竹林可持续性发展的经营模式,可作为毛竹林覆盖的配套经营措施在生产上推广应用。
In order to study the economic benefits and ecological restoration role in the croprotation mode of interplanting Dictyophora echinovolvata after covering PhyUostachys edulis, many experiments were made on different management modes of 1 a coveting Ph. edulis-1 a interplanting D. echinovolvata in the on-and-off year Ph. edulis pure forest. The results showed that： （1） The net income of the eroprotation management mode of 1 a covering Ph. edulis-1 a interplanting D. echinovolvata for two years has reached 180,000 yuan/hm2, with the input-output ratio of 1：3.29, is 19.6 times and 1.6 times that of the traditional single management mode and of 1 a coveting Ph. edulis-1 a natural nurturing management mode, respectively. （2） Compared with the management mode ofl a covering Ph. edulis-1 a natural nurturing management mode, the croprotation mode of covering Ph. edulis-1 a interplanting D. echinovolvata has an obvious advantage in the effect of ecological restoration, such as the decomposition of organics covering in high carbon to nitrogen ratio （C/N）, soil improvement and soil fertility cultivation of woodland, soil fertility cultivation, and can effectively prevent Ph. edulis forests lead to the decline due to the cover in woodland. So the croprotation mode of interplanting D. echinovolvata after covering Ph. edulis, which is a management mode in sustainable development of Ph. edulis forests, can be used as supporting management measures of Ph. edulis forests covering for popularization and application in production.
