| 通过观测试验发现,河西沿沙漠地区具有较东部葡萄产区优越的生态气候条件。表现为:春季气温升高快,农业界限温度间隔日数短,热效率高,树体萌动早;营养和果实生长期光温适宜,相互匹配好,营养生长期日平均气温在15.2~18.2℃,日照时数在8.9~10.2 h,枝叶生长迅速,树势恢复快。果实快速膨大期平均气温20.4~22.3℃,日照时数在8.4~9.3 h,期间高温日数少,有利于果实快速膨大,果实生长发育良好;果实成熟期光能资源丰富,日光能系数在5.1~5.4之间,日较差大(12.6~14.5℃),加之降水少、空气干燥,成熟前降温快,利于糖份积累和风味保持,果实品质好。分析了影响酿酒葡萄生育的不利气象灾害,提出了相应的趋利避害措施和提高河西气候资源利用率的途径。 |

| Through experiments and observations,it has been proved that the eco-climate condition along the desert area in Hexi Corridor is superior to that in the eastern producing region of brewing grape in China.The temperature rises fast in spring,the interval days of agricultural demarcation temperature is short,the heat efficiency is high,and the fruit trees sprout early.The light and temperature conditions during both the vegetative period and the reproductive period are suitable and matched well each other.The daily average temperature during the vegetative period is between 15.2℃ and 18.2℃,and the daily sunshine duration is from 8.9 h to 10.2 h,being beneficial to the rapid growth of branches and fast recovery of trees.The average temperature during the fruit expanding period is from 20.4℃ to 22.3℃,the daily sunshine duration is from 8.4 h to 9.3 h,and the days with high temperature is few,being propitious to the rapid development of fruits.The light energy during the fruit ripening period is abundant,the light energy coefficient is between 5.1 and 5.4,the daily variation range of temperature is between 12.6℃ and 14.5℃,the precipitation is short and the air is dry,and the temperature before ripeness is reduced fast,being favorable to the sugar accumulation and flavor keeping in fruits.In addition,the paper analyzes the unfavorable meteorological disasters that influence the growth of brewing grape,and puts forward the relevant countermeasures to improve the utilization ratio of climate resources in Hexi Corridor. |
