摘　　要：随着赣东北地区雷竹林分的逐年增加,覆盖投产的林木面积也逐年扩大,砻糠、稻草等常规覆盖材料收集越来越困难、售价也越来越高,寻找新的覆盖替代材料,降低生产成本,是我省雷竹生产亟待解决的问题。为此,本文基于2013—2015年的研究结果,采用正交实验法,对不同林龄的林分采用不同覆盖中层材料配方和厚度进行覆盖试验。结果显示:6年生林分开始首次覆盖,覆盖中层材料每667 m2采用菜饼350 kg+麦麸250 kg+鸡粪350 kg配方,覆盖20 cm出笋较早;采用菜饼350 kg+麦麸250 kg+油茶果壳350 kg配方,覆盖20 cm笋期较长;采用菜饼350 kg+麦麸250 kg+鸡粪350 kg+油茶果壳350 kg配方,覆盖30 cm时,林分年度竹笋产量和持续产量均较好。With the increase of the forest of Phyllostachys violascens in Jiangxi Province,it is more and more difficult to collect conventional mulching materials such as rice chaff and rice straw,and the price is higher and higher.To find new mulching alternative materials and reduce production cost are the urgent problems to be solved in the production of Phyllostachys violascens in Jiangxi Province.Therefore,based on the research results of year 2013 to 2015,this paper adopts the orthogonal experiment method to carry out the covering experiment for different age stands with different covering medium material formula and thickness.Different covering materials and thickness were used to cover different age stands,the results showed that 6-year-old forest began to be covered for the first time,and the shoots appeared earlier when rapeseed meal 350 kg+wheat bran 250 kg+chicken manure 350 kg formula was used and covered 20 cm,and the shoot period was longer when rapeseed meal 350 kg+wheat bran 250 kg+Camellia shell 350 kg formula was used and covered 20 cm.When rapeseed meal 350 kg+wheat bran 250 kg+chicken manure 350 kg+Camellia shell 350 kg formula was used(per 667 m2)and covered 30cm,the annual bamboo shoot yield and sustainable yield were better.
