江西通过近九十年的桉树引种,选择出了抗寒力较强,生长表现较好的桉树品种——赤桉。在五十年代末,就在全省大范围地开展了赤桉的“四旁”植树和营造赤桉片林,并已形成了现在的赤桉优良次生地理种源贵溪赤桉。特别是进入八十年代后期,我省营造了大面积的赤桉。人工片林,累计达3万多亩,另“四旁”植桉达140万株。但是生产上使用的种子,主要来自经改良或测定的林分,行道树或孤立木,遗传品质较差,造成林分生产力不高,为
Jiangxi nearly nine decades through the introduction of eucalyptus, choose a strong cold hardiness, good growth performance of eucalyptus species - Eucalyptus. In the late 1950s, the “all around” planting of Eucalyptus globulus and the planting of Eucalyptus globulus forest were extensively carried out in the whole province. Guixi Eucalyptus grandis, an excellent secondary geography provenance of Eucalyptus grandis, has now been formed. Especially into the late eighties, our province has created a large area of Eucalyptus. Artificial forest, a total of up to 30000 acres, the other “around” planting 1.4 million trees. However, the seeds used for production mainly come from the improved or measured stands, street trees or isolated woods, with poor genetic quality, resulting in low productivity of stands
