为探索提高毛竹笋芽萌发率的途径，本试验用随机区组和正交设计方法在毛竹成林内分别布置了三个对比试验，以研究施用激素，微肥和硝酸稀土等外源物质对毛竹成林发笋和成竹数量的影响效应。对连续4年的观测分析表明，试验条件的毛竹林施用硝酸稀土处理的发笋数和成竹数与对照相比差异显著，且毛竹林对其施用浓度有较大的适应范围。施用激素和微肥处理的毛竹成林的发笋、成竹数与对照相比差异不显著，且较大浓度的微肥处理对发笋和成竹有不利影响。
In order to explore ways to improve the germination rate of bamboo bud shoots, three randomized trials and orthogonal design methods were used to study the effects of exogenous substances such as hormones, trace fertilizers and rare earth nitrate Effect of Shooting and Bamboo Shoots in Chenglin Forest. The observation and analysis for 4 consecutive years showed that there were significant differences in the number of bamboo shoots and the number of bamboo shoots when treated with rare earth nitrate in the bamboo forest under test conditions compared with the control, and the bamboo forest had a larger adaptation range for its application concentration. The bamboo shoots and the number of bamboo shoots treated with hormone and micronutrient fertilizer were not significantly different from those of the control, and the treatment of the micro-fertilizer with larger concentration had an adverse effect on bamboo shoots and bamboo shoots.
