刺槐细短根埋根育苗技术试验

摘要

Objective] Improve the reproduction rate of Robinia pseudoacacia, accelerate plus tree breeding techniques. [Method] Choose different time, different length and diameter of Robinia pseudoacacia root segment buried root seedling technique experiment was carried out. [Result] From insects awaken to the vernal equinox, 3~5 cm in length, diameter of 1.5~3.0 cm root segment buried root seedling is advisable. [Conclusion] The results provided the technical basis for plus tree seedling breeding promotion of Robinia pseudoacacia.%[目的]提高刺槐繁殖率，加速优树繁育技术。[方法]选用不同时间，不同长度和粗度的刺槐根段进行埋根育苗技术试验。[结果]从惊蛰到春分时期、长度为3～5 cm、粗度为1.5～3.0 cm的根段埋根育苗为宜。[结论]研究结果为刺槐优树苗木繁殖推广提供了技术依据。
