沙漠边缘酿造葡萄生长气象条件及生态响应

Meteorological environment of brew grapes in edge-desert and their response to ecological environment

  • 摘要: 根据沙漠边缘新开发酿造葡萄生长发育的试验观测资料,分析了“梅鹿辄”、“品丽珠”等7个酿造葡萄品种生育进程和气象条件。结果表明:沙地酿造葡萄果实生长关键期在7月上旬到8月上旬,含糖量累积关键期为8月份。影响葡萄含糖量的气象因子主要有积温、阶段温度日较差累积值和相对湿度。在分析沙地葡萄园土壤水分随时间、深度变化的基础上,估算出沙地葡萄年生长期平均耗水423.2mm,萌芽到展叶期耗水最少,盛花到成熟期耗水最多,展叶到盛花期和成熟到落叶期耗水量大致相近。试验结果表明在沙漠沿线种植酿造葡萄具有耗水少、效益高的优势,既不减少耕地,又能增加当地农民经济收入,具有良好的生态和经济效益,对绿洲生态环境保护有积极促进作用。

     

    Abstract: Developmental procedures and corresponding meteorological environments of 7 brew grape cultivars (Meiluzhe, Pinlizhu,etc)in edge-desert were investigated. Results show that brew grape key fruit development period is from the first ten days of June to the first ten days of August and key sugar accumulation period is August.Important factors that affect grape sugar content include accumulated temperature,accumulated amplitude of diurnal temperature variation, and relative humidity. Analysis of soil water variation with time and soil depth indicates that grape average water consumption in the entire growth period is 423.2mm. Grape consumes the least water from budding to leaf growth, and the most water from blossom to maturity.From leaf growth to blossom and from maturity to leaf shedding,grape consumes similar amounts of water.Brew grapes in edge-desert consume less water than other crops and bring more benefits by increasing farmers’income without reducing cropland area.
