【摘要】 通过对珍贵树种华盖木在湛江引种后的生长发育状况、抗逆性和适应性进行系统的观察和比较后得知,从原产地云南购回种子直接播种育苗种植的华盖木A4处理方法引种3.5年后的保存率可达到56%以上,生长较好,抗性也较强,是较适应在湛江地区采用的引种方法。从原产地云南购回大小苗木未经驯化直接或间接种植的华盖木A1、A2、A3不适应在湛江地区采用的引种方法。更多还原

【Abstract】 The growth and development status,resistance and adaptability of precious tree Manglietiastrum sinicum in Zhanjiang were observed and compared systematically.The seedlings of Manglietiastrum sinicum were propagated by the seeds from Yunnan( A4),and the adaptability of seedlings were studied after three and a half years.The preservation rate of Manglietiastrum sinicum could reach more than 56% introduced,which grew well with strong resistance. The introduction method,which directly or Indirectly planted the nursery stocks from Yunnan without domestication( A1,A2 and A3),could not be suitable for use in Zhanjiang area.更多还原
