摘　　要：筇竹(Qiongzhurea tumidinoda)是中国西南地区特有竹种,是国家三级保护的稀珍竹种,其笋品质上乘,被誉为“笋中之王”。云南省昭通市是筇竹的自然分布中心,其天然筇竹林面积占中国天然筇竹林面积的73.18%。由于管理缺失,大部分筇竹林长期处于低产、低效状态,资源浪费严重。为充分发挥筇竹资源优势,提高竹笋产量,对低产筇竹林开展了科学施肥试验。结果表明,施肥能使筇竹发笋时间提前,笋期延长,发笋数量增加,单位面积笋产量明显提高,肥料以尿素+复合肥+厩肥混合施用效果最佳。Qiangzhurea tumidinoda is a bamboo species endemic to Southwest China. It is a rare bamboo species under national third-level protection. Its shoots are of high quality and known as the “king of bamboo shoots”. Zhaotong City in Yunnan Province is the natural distribution area of Q. tumidinoda, and its natural Q. tumidinoda forest accounts for 73.18% of the country total in area. Due to the lack of management, most Q. tumidinoda forests there have long been low-yield and low-quality, which results in serious waste of resources. In order to give full play to the advantages of Q. tumidinoda resources and improve the yield of bamboo shoots, fertilization experiments are carried out on low-yield bamboo forests. The results show that fertilization could make shooting ahead of time, prolong the shoot period, increase the number of shoots, and significantly improve the shoot yield per unit area. The compound application of “urea + compound fertilizer + manure” has the best effect on shoots yield.
