| 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. |
