黄连木(Pistacia chinensis Bunge)是落叶乔木。分布很广,北自河北、山西,南至两广、台湾,均有野生和栽培。木材供建筑、家具、车辆、农具、雕刻等用,种子可榨油,树皮、叶又可做药用。我站从1980—1985年进行了引种试验,以了解它在滨海盐碱土上生长耐盐情况,通过试验发现它是一个适应性强,很耐盐碱,而且病虫害很少的树种,6年生平均树高4.4米,胸径5.7厘米,长势良好。现将结果初报如下: 一、试验地自然概况 试验地设在江苏省射阳县省沿海防护林试验站内。地处亚热带北缘,年平均气温13.7℃,最高气温35.8℃,最低气温-10.4℃,年降雨量1034毫米,雨量多集中在7—8月。土质为中壤,pH7.5—8.5,土壤含盐量(指NaCl,下同)一般在0.1—0.2％范围内,海拔高2米左右,潜水面1.6—2米,雨季常升高到1米以内。
Pistacia chinensis Bunge is a deciduous tree. Distribution is very wide, north from Hebei, Shanxi, Guangdong and Guangxi to the south, Taiwan, are wild and cultivated. Wood for construction, furniture, vehicles, farm tools, carving and other purposes, the seeds can be squeezed oil, bark, leaves and can do medicinal. We conducted a pilot experiment from 1980 to 1985 to understand its salt-tolerant growth on coastal saline-alkali soil. It was found by experiment that it is a tree species that is highly adaptable, saline-tolerant and has few pests and diseases. The 6-year average Height of 4.4 meters, diameter of 5.7 cm, good growth. The results of the first report is as follows: First, the experimental nature of the test site located in Sheyang County, Jiangsu Province Coastal Shelter Forest Experimental Station. Located in the northern margin of the subtropical zone, the annual average temperature of 13.7 ℃, the highest temperature of 35.8 ℃, the lowest temperature of -10.4 ℃, the annual rainfall of 1034 mm, rainfall mostly concentrated in the July-August. The soil is in the soil, pH7.5-8.5, soil salinity (referring to NaCl, the same below) is generally in the range of 0.1-0.2%, about 2 meters above sea level, diving surface 1.6-2 meters, the raining season often rises to 1 Within meters.
