宁蒗县马铃薯种薯生长气候适应性分析OA

The potato industry is the traditional and distinctive advantageous agricultural industry in Ninglang Yi Autonomous County(Ninglang County),Yunnan Province.In 2021,the seed potato industry in Ninglang County was established as its leading industry under the"one county,one industry"policy.Using meteorological observation data in Ninglang County from 2015 to 2024 and growth-stage observation data provided by the seed potato industry,the average temperature,precipitation and sunshine during growth stage were used as zoning factors.The suitability of temperature,precipitation,and sunshine for potatoes at different growth stages and their spatial distribution were analyzed by applying climate suitability calculation methods.The overall climate conditions in Ninglang County were suitable for potato growth,with relatively stable interannual climate conditions,but significant regional differences exist.The tuber formation and bulking stages have the highest water requirements,and areas with low precipitation become potential yield-limiting factors.Overall temperature suitability was relatively high,but there was a risk of low temperatures in high-altitude areas.Comprehensive analysis indicated that temperature from June-August,precipitation in July,and sunshine duration from July to August were the key factors driving the spatial differences in suitability,with sunshine duration playing a crucial role during critical growth stages.The findings could provide a scientific basis for optimizing the potato production layout and climate risk management in Ninglang County.
