云南红豆杉人工药用原料林的经营技术

对云南红豆杉人工药用原料林的种植技术及经营方式的研究试验进行了阶段性综合总结,认为云南红豆杉具有喜荫喜湿喜肥,对温度的适应范围广的特性,提出了可以扩大栽培区域的观点。分析了云南红豆杉最适宜种植的气候土壤条件是:年降雨量在1500mm以上,年干燥度<0 8,黑土层>20cm的肥沃砂壤至轻壤土,作为药用原料林种植地应选择海拔高度为1300～2200mm的温暖及温热气候。研究了"扦插繁殖、密集种植、苗期利用"的原料林种植经营方式,大棚扦插成苗达89 56%,4年生林木生物量产量达到15000～32250kg/hm2(风干含水率11%)。并对采穗圃与苗木更新、人工复合群落等营造技术进行总结和论述,报导了云南红豆杉人工药用原料林的生物量及紫杉醇含量的测定结果。

Management Technology of Medicinal Material Plantation of Taxus Yunnanensis

Experiments on Planting and management technology of Taxus yunnanensis were generally summarized, the result shows that the Taxus yunnanensis grow well in shady, humid and fertile conditions, and adapt to a wide range of temperature. The planting area was suggested to expand. According to the analysis of experiments, the best climate and soil condition is that the yearly rainfall is over 1 500 mm, the evaporation is blow 0.8,the thickness of black soil horizon is over 20cm, the soil is sandy loam or light loam, the altitude is from 1 300 to 2 200 m, warm weather. Management technology is summarized as propagation by cutting, planting in high density and making use of the seedlings. Cutting survive rate is 89.56% in greenhouse, and growth volume is 15000 to 32250 kg/hm2 in four years. some planting technology such as Nursery construction, seedling updating and artificial community were summarized and discussed. The growth volume and content of pacilitaxel were also reported in this paper.
