在广东东部滨海风砂土地区先后进行松类、相思和余甘子等16个树种的引种造林试验,获得成功的有湿地松、洪都拉斯加勒比松、古巴加勒比松、马占相思、大叶相思和余甘子等6个树种。湿地松造林面积已达660多公顷,丰产林11年生树木的生长量每公顷达273立方米,比丘陵地生长好,比一般造林增产63%。其余几种松树也比丘陵地的马尾松生长好(砂地马尾松比丘陵地生长差)。余甘子3年就开花结实,生长良好,又为滨海砂地增加了新的造林树种。以上树种的引种成功,充分的利用了砂地,提高了经济效益。
In the east coastal windy sand area of Guangdong have pine, Acacia and Phyllanthus embarked 16 species of afforestation trials, the success of the pine, Honduras Caribbean pine, Cuban pine, Acacia mangium, Acacia and more Gan sub 6 species. Slash pine afforestation area has reached more than 660 hectares, the growth of 11-year-old trees in high yield growth of up to 273 cubic meters per hectare, than the hills to grow well, 63% more than the average afforestation. The rest of the pine trees also grew better than the Pinus massoniana hills (poor growth in the Masson Masson hills). Emblica flowering 3 years to grow strong, good growth, but also for the coastal sand added a new afforestation species. The successful introduction of the above species, the full use of sand, improve economic efficiency.
