我所于1981年5月采用高标准营林措施,用大叶相思和雷林1号桉作混交树种,营造速生丰产薪炭试验林100亩。目的是了解大叶相思和雷林1号桉的种间关系和混交效益。摸索营造速生丰产薪炭林的途径。试验四年多来,进行多次的观察、调查,现将试验初步结果整理如下:一、基本情况试验地位于北纬23°18′,东径116°40′,属南亚热带季风气候带,气候温和,雨量充沛,热量丰富。年平均气温21.2℃,年雨量2,126.9毫米,日照1,922.8小时,空气相对湿度83％。海拔80米左右,地势较为平坦,土壤属花岗岩发育的厚土层薄腐殖质赤红壤,土壤肥力较差。林下植被主要有芒箕、桃金娘、鹧鸪草、鬼灯笼等。
In May 1981, I used a high standard of forest management measures, using Acacia crassipes and Eucalyptus eucalyptus as mixed tree species, to create 100 mu of fast-growing and high-yielding pilot forest. The purpose is to understand the Acacia and Larin 1 Eucalyptus interspecific relationships and mixed benefits. Explore ways to create fast-growing fuelwood forest. The test is conducted over the past four years with many observations and surveys. The preliminary results of the trial are summarized as follows: I. Basic conditions The test site is located at 23 ° 18 ’north latitude and 116 ° 40’ east longitude and belongs to the southern subtropical monsoon climate zone with mild climate , Abundant rainfall, rich heat. The annual average temperature of 21.2 ℃, annual rainfall of 2,126.9 mm, 1,922.8 hours of sunshine, air relative humidity of 83%. About 80 meters above sea level, the terrain is relatively flat, the soil is a thick layer of granite developed humus Latosolic soil, soil fertility is poor. Undergrowth vegetation are mainly Kei Kei, myrtle, partridge grass, ghost lanterns and so on.
