新晃县种植黑老虎的气候条件分析

Analysis of climate conditions of planting Kadsura coccinea in Xinhuang,Hunan

为保护黑老虎资源的可持续发展,推广黑老虎的人工种植规模,减少气象灾害带来的损失,促进当地经济发展和农民收入,对新晃县国家一般站1981—2018年38年气候资料进行了分析、对比和研究。结果表明:①新晃县独特气候条件下,适合规模种植黑老虎;②新晃县黑老虎定植时间安排在3月份后,可避免低温冷害,提高幼藤保存率;③新晃县不适合在自然全光照条件下栽培黑老虎,应该采取仿生态栽培技术,将黑老虎种植在疏林下或者搭建遮阳网,以避免高温灼伤,提高保存率;④种植黑老虎尽量选择在水源充足的地方,防止干旱对黑老虎生长的影响。

In order to protect Kadsura coccinea resources,to realize sustainable development,to increase the artificial planting scale of Kadsura coccinea,to reduce the losses caused by meteorological disasters,to promote local economy and to increase the income of farmers,we analyzed,compared and studied the climate data of Xinhuang National General Station from 1980 to 2018.The results show that:①the unique climate conditions of Xinhuang is suitable for planting Kadsura coccinea on a large scale;②the planting time should be arranged after March,so as to avoid low temperature and to improve the survival rate of the seedlings;③it is not suitable for the cultivation of Kadsura coccinea under full natural light in Xinhuang,so imitated ecological cultivation technology should be adopted,and Kadsura coccinea should be planted under sparse forest or artificial sunshade net,so as to avoid high temperature and burn;④Kadsura coccinea should be planted in places with sufficient sources of water,so as to reduce the influence of the dry zone on the growth of Kadsura coccinea.
