摘要
以华南赤红壤为栽培基质,采用盆栽法研究了保水剂对桉树幼苗抗寒生长及存活率的影响。结果表明,保水剂可有效提高华南赤红壤的保温性能,试验期内经受2次降温过程后,保水剂用量为0.5%处理的桉树叶片含水量较高,而顶部嫩梢枝条的含水量明显随保水剂用量增大而增大;保水剂用量增大有利于桉树苗木抗寒生长,但侧枝生长较好,出现横向生长现象,因而不利于株形向上生长。
South China crimson soil was used as materials, influence of water-reserving agent on cold-resistance of eucalyptus was studied. The results that showed temperature-keeping property of the crimson soil was improved by the water-reserving agent, and water content of the leaves and branches increased with increasing of the dosage of water-reserving agent; the height of the eucalyptus was improved when the dosage of the water-reserving agent increased, while side branches grown more than main branches.
