马尾松为广西最主要的造林树种,既往均是用一年生苗造林。在桂南地区一般成活率不高。广西僮族自治区林科所及七坡林场等试验单位于1958年开始共同协作进行马尾松秋播春植造林试验(9—10月份育苗;12—次年3月份造林)。根据多点试验及七坡林场大面积造林(共造44,770亩)结果,并经过1961年底区林业厅鉴定证明此法可在桂南一带推广。
Masson pine is the most important afforestation species in Guangxi, and all of them were afforestation with annual seedlings. In South Guangxi general survival rate is not high. Experimental units in Guangxi Autonomous Region, Lincoln Institute and Qipu Forest Farm started collaborative work in 1958 to conduct masson pine planting experiments (September-October nursery; 12-March planting). According to the results of multi-point experiment and afforestation of a large area in Qipu Forest Farm (44,770 mu in total), it was certified by the District Forestry Bureau at the end of 1961 that this method could be promoted in the Guinan area.
