为丰富我省的树种资源,提高林业生产水平,我院从1964年始,曾先后从林业部引进的松树种中得到湿地松、火炬松、海岸松、意大利松等进行栽培试验。1982年。又从北京种苗局得到辐射松、湿地松、加勒比松三个国外松树种,作进一步引种试验。为使所得数据可靠,我们严格按照田间试验设计的要求,并用乡土树种云南松作时照进行栽培对比试验。4年来的生长情况证实,辐射松在参试的4个树种中名列前矛。
In order to enrich tree resources of our province and improve the level of forestry production, from 1964, our institute had successively obtained the cultivation tests of Pinus elliottii, Pinus taeda, Pinus thunbergii, Pinus taidiae, etc. from pine species introduced by the Ministry of Forestry. 1982 And from Beijing Seedling Bureau Radiata pine, Pinus elliottii, Caribbean pine three foreign pine species for further introduction test. In order to make the data reliable, we strictly follow the requirements of the field trial design, and compared with the native tree species of Yunnan pine for photosynthesis experiments. Four years of growth confirmed that Pinus radiata was among the top four tested species.
