摘要
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。
This experiment was designed for finding out the new ways to promote mosobamboo rhizome to produce more shoots. A randomized block design with three duplicatesand two orthogonal designs with two duplicates, were adopted. In the orthogonal experiments there are three factors with two levels for each,i. e.,three kinds of hormons and threekinds of micronutrients,so as to find out the effects of those treatments on the shoot-producing of moso rhizomes.The number of shoots in spring of the metioned-above experiments had been monitoredcontinuously for two years and the data was analysed with objective analysis for orthogonaldesign and variance analysis for the randomized block experiment respectively. The resultsshowed that effect of rare earth on promoting moso bamboo to produce shoots was obiviouscompared with the control and there was a wide range of absorption to rare earth for mosobamboo stand. Effect of hormones and mocrouutrients on moso bamboo to produce shootswas not so obvious.
