Study on Meteorological Service Indexes of Important Pastoral Activities in Southern Huangnan Tibetan Autonomous Prefecture of Qinghai Province
In this paper,the meteorological service indexes of important pastoral activities in southern Huangnan Tibetan Autonomous Prefecture of Qinghai Province were studied by selecting the surface and ecological meteorological observation data of the southern meteorological station of Huangnan Prefecture of Qinghai Province from 2003 to 2022,combining with the investigation of the occurrence time of pastoral activities,using mathematical statistics method for statistical analysis.The results show that:(1)The summer transition time in southern Huangnan is about 20 days after the first day of the daily average temperature stability through≥5 ℃,and the Henan area is the first to third pentads in June.The Zeku area is the third and fifth pentads in June and the second pentad in July.(2)The suitable time for autumn transition in southern Huangnan is 10 to 20 days after the end date of daily average temperature steadily passing≥5 ℃,and Henan is the first,third and fourth pentads in October.The Zeku area is the third pentad in September and the first to second pentads in October.(3)The best shearing period in southern Huangnan is from the first day of daily average temperature steadily passing≥10 ℃ to the end day of daily average temperature≥12 ℃.The best shearing period in Henan area is in the middle and late July,and in Zeku area is from late July to early August.(4)The optimal slaughter period in the south of Huangnan was 20 to 30 days after the end date when the daily average temperature passed≥0 ℃ stably.The optimal slaughter period in Henan was from mid-October to early November,and the optimal slaughter period in Zeku was from mid-October to late October.(5)In southern Huangnan,December to January and February to March of the following year is the peak period of production of winter lambs and spring lambs.During this period,the climate conditions are harsh,which has a great impact on the survival rate of lamb reproduction.It is recommended to take measures such as cold prevention and disease prevention,supplementary feed and other measures according to the actual situation.The research results have important reference value for reasonable arrangement of animal husbandry activities,prevention of natural disasters,full use of climate and grassland resources,and promotion of efficient and high-quality animal husbandry production.
