我国黑荆树适生区的划分及各区栽培技术要点

DIVISION OF SUITABLE AREA FOR GROWING WATTLE, ACACIA MEARNSII, AND KEY POINTS OF PLANTING TECHNIQUE IN EACH AREA

摘要: 黑荆树(Acacia mearnsii)原产澳大利亚,50年代引入我国。初期种植范围很广,南起海南岛中部(北纬190°)、北至大巴山麓(北纬32°)、东迄舟山群岛(东经1220°)、西达云南(东经1010°)的广大热带、亚热带地区。但很多地方因生态环境不适,引种失败或生长不良,使黑荆树生产形成几起几落的状况。由于其生长快、伐期短、用途广,树皮、木材都是工业的好原料,仍然受到南方各省的重视,近年来很多省都在兴办基地,一些未种植过的地区也积极引种。为了做到适地适树,充分发挥其生产潜力,本文拟对黑荆树的适生条件、适生区的划分和各区的气候特点以及针对这些特点应采用的栽培技术要点加以论述。

Abstract: Based on the distribution of 64 locations in wattle natural distribution in Australia and the data collected from 61 plantations in 30 more countries, 5 important factors were selected for determining the suitable climatic requirements for the growth of wattle.The experience of plantation wattle in China for over 30 years has been summarized.According to the comparison of climate and geographic distribution of wattle in China and other countries, China is a suitable country for growing wattle.Based on the results of our investigation, a division of suitable areas for growing wattle in China was made.Key points of planting method in each area were suggested.
