竹腔施肥对毛竹生长影响的初步研究

The effect of cavity-injection fertilization on the production of Phyllostachys edulis

通过随机区组试验设计,对比了竹腔施肥、常规施肥与不施肥3种措施对毛竹生长的影响。研究结果表明,竹腔施肥能有效提高毛竹生长,其出笋量、成竹量和新竹胸径比常规施肥措施分别提高了16.1%,42.8%和3.2%,该技术适合在闽西竹林分布区进一步推广应用。

The effect of three different fertilization treatments on the growth of Phyttostachys edulis by random block experimental design was researched, including cavity-injection fertilization, normal fertilization and no fertilization. The results showed that the cavity-injection fertilization can obviously improve Phyllostachys edulis production. Compared with no fertilization treatment, the bamboo shoot yield, new culms number and diameter of cavity-injection fertilization treatment were improve by 16.1%, 42.8% and 3.2% respectively. Therefore, the technology of cavity-injection fertilization should be promoted in the area of bamboo in the west of Fujian province.
