樟树是南方的一种珍贵用材和特用经济树种,主产于长江流域以南,我区亦有天然零星分布。随着工农业生产的不断发展,原有天然资源远远不能满足国需民用。我们于1961年营造了130亩樟树混交试验林,旨在探索樟树人工林的适宜混交树种和合理经营措施,以满足国计民生的需要,已初步获得良好效果。现将试验情况总结如下: 一、试验地概况试验地地处南亚热带地区,高温多雨,年平均降雨量1,650.7毫米,每年5-9月为雨季;年平均气温22.3℃,绝对最高温37.4℃,绝对最低温一般在0℃以上,时间极短,冬暖夏长,土层深厚,pH值5.0。土壤养分含量为:有机质1.64％、全氮0.075％、全磷0.026％、全钾0.28％,系浅海沉积物母质发育而成的强酸性灰棕色砂壤土。植被属灌木低草群落。
Camphor tree is a precious timber in the South and special economic tree species, mainly produced in the south of the Yangtze River valley, I also have natural sporadic distribution. With the continuous development of industrial and agricultural production, the original natural resources far can not meet the needs of the people. In 1961, we constructed 130 acres of camphor tree mixed experiment forest, in order to explore suitable mixed camphor tree species and reasonable management measures to meet the needs of national economy and the people’s livelihood, has achieved initial good results. Now the test conditions are summarized as follows: First, the test site Overview Experimental site is located in the southern subtropics, high temperature and rainy, with an average annual rainfall of 1,650.7 mm, 5 to 9 months each year for the rainy season; annual average temperature of 22.3 ℃, the absolute maximum temperature of 37.4 ℃, The absolute minimum temperature is generally above 0 ℃, the time is very short, warm in winter and summer, deep soil, pH 5.0. Soil nutrient content is 1.64% of organic matter, 0.075% of total nitrogen, 0.026% of total phosphorus and 0.28% of total potassium, which is a strongly acidic, beige sandy loam soil developed from the parent material of shallow sea sediments. Vegetation shrubs low grass community.
