研究經过 馬尾松植树造林,桂南地区一向用一年生苗。在丘陵干旱地区,因早春雨少,土壤干旱,苗木定植不下去;如果等到雨量充沛时再定植,苗木又迅速抽苔,成活率也不高。为了解决这个問题,广西沙塘林业試驗站和国营六万林場,1955—1956年,曾用小苗造林,認为希望很大,但缺乏系統的材料和数据。1957—1962年,广西林业科学研究所和国营七坡林場共同負責进行馬尾松異龄苗造林的研究,协作单位有夏石、西山、小龙等三个林业試驗站。
After studying Pinus massoniana afforestation, Guinan has always used annual seedlings. In arid regions of the hilly area, the seedlings are not planted because of the drought in early spring and the drought of the soil. If the seedlings are planted again when the rainfall is abundant, the seedlings are rapidly bolted and the survival rate is not high. To solve this problem, Guangxi Shatang Forestry Experimental Station and state-owned 60,000 forest farms, 1955-1956, afforestation with seedlings, that there is great hope, but the lack of systematic materials and data. From 1957 to 1962, Guangxi Forestry Research Institute and State-owned Qipu Forest Farm were jointly responsible for the research on afforestation of different age groups of Pinus massoniana. There are three forestry experimental stations including Xiashi, Xishan and Xiaolong.
