我们于1977年开始在云南省林科院的普文试验林场对山桂花的采种、育苗和栽培技术进行了试验研究。现有不同年龄的试验林500亩;此外,在屏边县白河也进行了山桂花山地造林的试验研究。1987年运用试验研究所得技术分别在勐腊、屏边、思茅、景谷等县进行较大面积的山地造林,收到可喜的效果,目前全省造林面积达5244.5亩。通过10余年来的试验研究以及实践验证,已形成山桂花采种育苗和山地造林的配套适用技术。本文仅就造林技术部分进行总结。一、造林地选择 1.立地条件经多年的试验结果表明,在适生气候区内,山桂花的生长与立地条件有明显的相关。立地因子——坡位、坡向、坡形、土壤等的差异与林木生长的关系,经回归分析,按生长量指标划分出三个类型,如表1。
In 1977, we started the experiment on the seed collection, nursery and cultivation of Osmanthus fragrans in the Pulvin Experimental Forest Farm of Yunnan Academy of Forestry. There are 500 mu of experimental forest of different ages. In addition, experimental research on afforestation of Shan-Guihua Mountain in Baihe County, Pingbian County is also carried out. In 1987, the technology of experimental research was used to afforestation in a large area in Mengla, Pingbian, Simao, Jinggu and other counties, respectively, and received gratifying results. At present, the afforestation area in the whole province is 5,244.5 mu. Through more than 10 years of experimental research and practical verification, it has formed a suitable application technique of seedling cultivation and mountain afforestation of Osmanthus fragrans. This article only summarizes the part of afforestation technology. First, the choice of afforestation 1. Site conditions After many years of test results show that in the adaptive climatic zone, the growth of sweet-scented osmanthus Shan and site conditions were significantly related. Site factors - slope position, aspect, slope shape, soil and other differences and the relationship between the growth of trees, the regression analysis, divided by the amount of growth indicators of the three types, as shown in Table 1.
