摘　　要：对山地麻竹笋用林采用回归正交试验设计,施用有机肥和生长调节剂,分析研究了笋林的出笋量和经济效益。结果表明:不同处理麻竹林竹笋产量、挖笋数量、竹笋个体质量分别为11 451-25 440 kg.hm-2、7 840-15 360个.hm-2、1.41-1.66 kg.个-1;有机肥和生长调节剂对竹笋产量和数量的影响较为显著,竹笋产量和数量随有机肥施用量的增加而升高;经分析,竹笋产量、数量与施肥关系回归方程拟合良好;麻竹最佳施肥方案为有机肥2 484.8 kg.hm-2,生长调节剂用量为6.006 L.hm-2;竹笋最高产量的施肥量为有机肥2 482.35 kg.hm-2,生长调节剂用量为6 L.hm-2。各处理麻竹施肥收益的变化范围为-5 699.5-7 310.2元.hm-2,麻竹施肥对竹林经营收益影响显著,竹林施用有机肥和生长调节剂与竹林收益回归方程拟合良好。Through fertilizing organic fertilizer and growth regulators to Dendrocalamus latiflorus shoot-used forest planted on hills with quadratic regression orthogonal test design, the shoots output and economic benefit were analyzed. The results showed that the range of shoots output, quantity and individual weight were 11 451 -25 440 kg·hm^-2,7 840-15 360 shoots·hm^2, and 1.41- 1.66 kg·shoot^-1 Fertilizing organic fertilizer and growth regulators had remarkable influence on shoots output. Shoots yield and quantity increased with fertilizer increasing. The regression equation of shoots yield and quantity with fertilizer fitted very well. The best fertilizing project was that organic fertilizer and growth applied at 2 484.8 kg· hm^-2,6. 006 L· hm^-2respectively. The fertilizing project for the highest yield was that organic fertilizer and growth applied at 2 482.35 kg· hm^-2,6 L· hm^-2. range of profit was -5 699.5 - 7 310.2 Yuan · hm^2. Fertilizing organic fertilizer had remarkable influence on profit. The regression equation between fertilizer and profit fitted very well.
