| 中文摘要: |
| 利用剑川国家气象站1991-2020年气象观测资料和剑川农业农技站提供的马铃薯2011-2020年生育期观测资料，采用气候适宜度计算方法，分析马铃薯关键生育期气象因子适宜性。结果表明：降水量是影响剑川马铃薯生长的关键因子，马铃薯生长前期和后期水分需求少，块茎膨大期水分需求多，但是芽条期至幼苗期及块茎膨大期至成熟期降水偏少，会影响生长发育和产量形成。在芽条期和块茎膨大期温度、日照对马铃薯生长不利，其余生育期均比较适宜。 |
| 英文摘要: |
| In order to study the comprehensive climate adaptability of each development stage of potato growth in Jianchuan County, meteorological observation data from the Jianchuan National Meteorological Station (1991–2020) and growth-period observation data from the Jianchuan Agricultural Technology Station (2011–2020) were used. The climate suitability method was used to analyze the meteorological factor suitability during the key growth stages. The results show that precipitation is the key factor affecting potato growth in Jianchuan. Water demand is low during the early and late stages of growth but high during the tuber expansion stage. However, precipitation is limited from the bud stage to the seedling stage and from the tuber expansion stage to maturity, which affects growth and yield formation. During the bud stage and tuber expansion stage, temperature and sunshine conditions are unfavorable for potato growth, while the remaining growth stages are suitable. |
