在毛竹种子育苗实践过程中,我们发现留床苗2年生的枝条基部生根能力很强,利用这种特性于1975年4月用毛竹实生苗枝条进行春插,取得了良好的效果。具体做法是:截取基部和中部,长8—12厘米,径粗0.3—0.5厘米,有节3—5个,保留叶2—3片,为减少蒸发将每片叶剪去2/3左右。用萘乙酸作低浓度慢浸和高浓度快浸二种处理。慢浸处理的浓度是100ppm,对照用蒸馏水,时间12小时,各30株;快浸处理的浓度是1,000ppm(50%乙醇溶液),对照是用50%乙醇,时间5秒,各19株。
In the process of seedling raising of bamboo seedlings, we found that the root of 2-year-old leaves of bed-keeping seedlings had strong rooting ability. By using this kind of characteristics, the spring seedlings of bamboo shoots were inserted in spring in April 1975, and achieved good results. The specific approach is: interception of the central and central, 8-12 cm long, diameter 0.3-0.5 cm thick, 3-5 knots, leaves 2-3 leaves, to reduce the evaporation of each leaf cut to about 2/3. Naphthalene acetic acid for low-concentration slow dip and high concentration fast dip two kinds of treatment. The concentration of slow-leaching treatment was 100ppm, control distilled water, time 12 hours, each 30; fast dipping concentration was 1,000ppm (50% ethanol solution), the control is 50% ethanol for 5 seconds, 19 strains each.
