根据各地经验,用越冬埋藏法处理毛白杨插穗是提高成活率的有效措施。但是越冬埋藏法插穗在窖内处理的时间太长,往往由于温度、湿度、通气等条件掌握失当使插穗腐烂或发芽。四年来我们学习了有关单位的经验,采用萘乙酸处理温床催根法,连续三年获得很高的成活率。1979年在保定区林研所也获得良好的结果。一、萘乙酸处理温床催根的方法选1年生插条苗作种条,苗高2—2.5米,基径2厘米左右。秋季落叶后(11月中旬)采集种条,及时埋藏在深60—80厘米的假植坑中,
According to local experience, the overwintering burial method to deal with Populus cuttings is an effective measure to improve the survival rate. However, the overwintering burial method cuttings in the cellar processing time is too long, often due to temperature, humidity, ventilation and other conditions to make improper cuttings decay or germination. In the past four years, we have learned the experience of the relevant units, using naphthalene acetic acid to deal with hotbed and rooting method, which has achieved a high survival rate for three consecutive years. Forest Research Institute in Baoding in 1979 also obtained good results. First, naphthalene acetic acid treatment of rooting method selected 1-year-old cuttings for planting seedlings, 2-2.5 meters high, basal diameter of about 2 cm. After the fall leaves (mid-November) collection of species, promptly buried in the deep 60-80 cm fake pit,
