火炬松、湿地松生长快,干形通直,抗逆性强,苏南丘陵山区已广为引种栽培。常州市所属三县地处苏南中部,1984年和1985年共造林13,567亩,已成为当地主要造林树种。 常州市火炬松、湿地松1年生苗有25％左右的等外苗春季不能出圃。如留床一年,等外苗2年生时普遍高达60厘米以上,造林难以成活。而遗弃等外苗则严重浪费。3月上、中旬国外松造林季节,苏南地区常有持续几天干燥风,使造林成活率难以达到85％(江苏省农林厅规定的造林合格标准),针对以上
Exotic loblolly pine, Pinus elliottii grow fast, stem straight, strong resistance, mountainous areas in southern Jiangsu has been widely introduced and cultivated. The three counties under the jurisdiction of Changzhou City are located in the central part of southern Jiangsu Province. In 1984 and 1985, a total of 13,567 mu of afforestation land was acquired, becoming the major afforestation tree species in the area. Changzhou City, loblolly pine, pine needles about 25% of one-year-old seedlings can not spring out of nursery. If stay bed for a year, and other seedlings 2 years old generally up to 60 cm above, afforestation is difficult to survive. The abandonment of other seedlings is a serious waste. March and mid-March, foreign pine forest season, southern Jiangsu often have a few days of dry wind, afforestation survival rate is difficult to reach 85% (Jiangsu Provincial Department of Agriculture afforestation eligibility criteria for afforestation), for the above
