从立地选择、竹林结构调整、深翻垦复、增施肥料、水分管理、适时挖笋、留笋养竹、覆盖催笋等方面总结了高产笋用毛竹林培育技术,并比较了几种处理模式对毛竹林出笋量和出笋时间的影响.结果表明,几种处理模式优劣顺序为:深翻垦复+覆盖谷糠+深施羊粪>深翻垦复+笋用复合肥+深施羊粪>深翻垦复+深施羊粪>深翻垦复+覆盖草木灰+深施羊粪.其中,最优模式冬笋产量可达 1.13 t/hm2,春笋数量可达 1 575 个/hm2,出笋初期和盛期分别提前 16 d和8 d.
Preliminary Exploration on High-yield Cultivation Techniques of Phyllostachys edulis Forests for Bamboo Shoots
The cultivation techniques of Phyllostachys edulis forest for high-yield shoot production were summarized from the aspects of site selection,bamboo forest structure adjustment,deep ploughing and reclamation,fertilizer application,water management,timely shoot excavation,shoot retention and bamboo cultivation,and mulching to promote shoot production,and the effects of several treatment modes on shoot production and shoot production time of P.edulis forest were compared.The results showed that the advantages and disadvantages of several treatment modes were as follows:deep ploughing and reclamation+covering rice bran+deep application of sheep manure>deep ploughing and reclamation+deep application of compound fertilizer for bamboo shoots+deep application of sheep manure>deep ploughing and reclamation+deep application of sheep manure>deep ploughing and reclamation+covering grass ash+deep application of sheep manure.Among them,the yield of winter bamboo shoots and the number of spring bamboo shoots in the optimal mode could reach 1.13 t/hm2 and 1 575 hm2,respectively,and the initial stage and peak stage of bamboo shoots were advanced 16 days and 8 days,respectively.
