摘要
采用田间试验方法研究了不同植物激素处理、不同覆盖措施、不同育苗时期、不同土壤质地和起苗留鞭等对斑竹竹鞭育苗的影响。结果表明：５种植物激素１５种组合处理竹鞭，与对照相比成活率均有不同程度提高，其中以ＡＢＴ２号浓度为５０ｍｇ／ｋｇ溶液处理６ｈ效果最佳；在４种覆盖措施中，以塑料小拱棚最为经济实用，与对照相比，其成活率提高了４０％，出笋期提早１０ｄ；２月下旬至３月上旬是斑竹埋鞭育苗的较好时期；在４种土壤质地中，以砂壤土埋鞭育苗成活率最高，土壤质地影响育苗效果的主次顺序为：砂壤土、壤土、粘壤土、粘土；起苗留鞭育苗可节约物料消耗，降低育苗成本１／３。上述技术的配套使用，使斑竹竹鞭育苗成活率达８１％以上。
By the method of field test and variance analysis, the techniques of seedling cultivation by clone propagation of Phyllostachys bambusoides f. tanakae is studied. The results showed that the survival rates increased more or less treated by 5 plant hormones treatents with the best effect of ABT NO.2 (50 mg/kg,6 h). From economical and practical viewpoint, the small arched plastic greenhouse is the best one among 4 mulching measures in which the survival rate increased by 40% over the control and the time of bamboo shooting was 10 days earlier than the control. There is significant difference between 5 seedling cultivation stages with the highest survival rate of the last tenday of February to the fist tenday of March. The sandy loam is the best soil texture for the seedling cultivation by burying cover rhizome. Compared with the control, the cost of reserving rhizome seedling cultivation after lifting could reduce one third. To the best match of all techniques above, the survival rate reaches to 81% or more.
