荔浦芋在桂林市推广种植的气象条件分析

Analysis on Meteorological Conditions for Promoting Cultivation of Lipu Taro in Guilin City

[目的]分析荔浦芋在桂林市推广种植的气象条件。[方法]利用荔浦县气象局1981～2010年的地面气象观测资料和荔浦县农业局提供的同期物候、产量及品质的资料，对荔浦芋年周期内各生育期适宜的气候条件进行了分析，总结出荔浦芋年周期内各生育期适宜的气候条件。同时对桂林地区的气象因子（温度、降水及光照）进行了分析，满足荔浦芋年周期内各生育期适宜的气候条件。并提出了在推广种植中可能遇到的不利气象因素。[结果]多数年份适宜在桂林地区推广种植荔浦芋，但在某些年份和某生育期，使产量降低，品质变差；桂林地区每年的3月中下旬-4月初多低温阴雨，幼苗定植期要避开低温阴雨天气。7—8月份多高温高湿的季节，病虫害易发生，采用高效栽培技术和及时的科学防治，注意收听当地的天气预报，大力推广应用病虫害的监测预警。[结论]该研究为推广荔浦芋在桂林地区的种植提供科学依据。

[ Objective ] To analyze meteorological conditions of promoting cultivation of Lipu taro in Guilin region. [ Method ] Using meteorologi- cal observation data from 1981 to 2010 in Lipu County Meteorology Bureau and Information on phenology, product and quality of the same period provided by Lipu County Agricultural Bureau, the climatic conditions in different growth stages for Lipu taro within a year were analyzed. The meteorological factors of temperature, precipitation and sunshine in Guihn region were analyzed, the unfavorable meteorological factors in the popularization of planting were proposed. [Result] The results showed that most of the year in Guilin area are suitable for expansion planting of Lipu taro, but in some years and growth period, lower the yield, quality becomes poor. The mid to late March to early April every year in Guilin area much cold rainy, seedling planting period to avoid cold wet weather. July-August a season of high temperature and high humidity, prone to disease and pest, the highly effective cultivation technology and timely prevention and control of science; pay attention to listen to the local weather forecast, vigorously promote application of pest and disease monitoring and early warning. [ Conclusion] The study can provide scientific data for promoting cultivation of Lipu taro in Guilin region.
