热带树种北移后,由于纬度、土质、土壤的酸碱值、气温、湿度、光照等生态环境条件、季节情况不同的制约,尤其是冬季低温、雨雪及干风寒冷天气,会对其成活、生长及观赏价值产生极大的影响,严重者甚至死亡。为此,如何增强这些热带树种的耐寒性,如何安全越冬,如何适应当地的自然生态环境,如何提高成活率而应采取的哪些种植养护措施将成为咱们园林建设者和养护者必须首要考虑的问题。
After the tropical species are moved northward, due to the different environmental conditions such as latitude, soil quality, soil pH value, temperature, humidity, light and other seasonal conditions, especially the winter low temperature, rain and snow and dry wind cold weather, it will survive , Growth and ornamental value have a tremendous impact, even severe cases of death. To this end, how to enhance the cold tolerance of these tropical species, how to win the winter safely, how to adapt to the local natural environment, and how to increase the survival rate should be taken as the cultivation and conservation measures that will be our garden builders and conservationists must first consider the issue .
