摘要
[目的]探讨与葛根产量关系密切的温、光、水农业气象资源变化特征.[方法]利用湖南娄底响莲实业发展有限公司提供的2008～2015年连续8年的葛根生产气象平行观测资料,采用统计分析方法,探讨葛根产量与气象条件关系.[结果]冷水江市葛根生长的适宜温度为20 ～30 ℃,当平均气温≥25℃、极端最高气温＞40℃时,葛根生长慢.气温偏低、光照偏弱、降水偏多的年份,产量偏高;气温偏高、光照偏强、降水偏少的年份,产量偏低.夏、秋干旱是影响冷水江市葛根产量的关键因子.[结论]该研究为葛根人工丰产栽培、产量提高提供了科学依据.
Abstract
[Objective] The aim was to discuss variation characteristics of agricultural meteorological resources such as temperature, light, water closely related with kudzu root yield.[Method] By using meteorological data during 2008-2015 provided by Hunan Loudi Xianglian Industrial Development Co.Ltd., adopting statistical analysis method, the relationship between kudzu root yield and meteorological conditions was analyzed.[Result] The optimal temperature for kudzu root growth in Lengshuijiang City was 20-30 ℃.When the average temperature was ≥25 ℃, extreme maximum temperature was ＞40 ℃, the growth of kudzu root was slow.The yield was relatively higher in the years with low temperature, weak sunshine and more rainfall;while under the conditions of high temperature, strong illumination and less rainfall, the yield of kudzu root was low.[Conclusion] The study provides a scientific basis for the artificial high yield cultivation and yield improvement of kudzu root.
