湿地松高效低耗持续丰产采脂新技术的研究

通过对8种刺激剂和5种施药周期及3种割沟频率组合采脂技术的筛选,2年的采脂试验,取得的松脂产量数据经本底产量对比研究,以采用复方植物生长调节剂作刺激剂,12天为一刺激周期,割沟频率4天1刀为组合的采脂方法效果最好。与常法采脂比较:平均单株全年松脂总产量提高20%以上;单刀产脂量提高100%以上;割面消耗降低50%;采脂工劳动生产率提高66.6%;经济效益提高1倍以上。

Research on the Techniques of Resin Tapping of Pinus elliottii

Based on the research on the techniques of resin tapping of Pinus elliottii with 8 plant growth regulators,5 time intervals and 3 methods,it indicated that the best method of resin tapping of Pinus elliottii was to use plant growth regulators 12d once and cutting 4d once.Compared with routine procedure:Resin total output in the whole year of average individual raises morethan 20%;The resin yield of single-bark improves more than100%;The consume of bark surface reduces by 50%;Adopt worker's labor productivity of tapping to raise by 66.6%;The economic benefits are doubled the above,It is the best,latest technology of tapping of Pinus elliottii at present.
