摘　　要：采用随机区组设计试验,分析对比竹腔施肥、普通施肥和不施肥3种处理对雷竹生长的影响。试验结果表明:竹腔施肥与普通施肥和不施肥比较,出笋数量分别增加12.11%和33.26%,退笋率分别降低3.3%和4.2%,经济收益分别提高14.0%和33.4%,新竹平均胸径分别增加0.25 cm和0.35 cm。综上所述,施肥对产笋量、成竹率、新竹径级和单位面积收益上均有积极的影响作用。不同施肥方式其作用效果为:竹腔施肥>普通施肥>不施肥。The randomized block design experiment was carried out to analyze and compare the effects of bamboo cavity fertilization,normal fertilization and without fertilization on the growth of Phyllostachys praecox f.prevelnalis.The results showed that the number of bamboo shoots increased by 12.11%and 33.26%,the rate of degraded bamboo shoot decreased by 3.3%and 4.2%,the economic benefits increased by 14.0%and 33.4%,and the average DBH increased by 0.25 cm and 0.35 cm respectively when fertilized into bamboo cavity compared with normal method of fertilization and without fertilization.In conclusion,fertilization had a positive effect on shoot yield,bamboo preserved rate,diameter class and benefits per unit area.The effects of different fertilization methods were as follows:bamboo cavity fertilization>normal fertilization>without fertilization.
