| 辣椒的移栽期与采摘期是辣椒的生长发育至关重要的环节，为了探究辣椒适宜移栽期与采摘期的分布规律，本文利用1980-2020年贵州省84个国家常规地面观测站的逐日平均气温等资料，基于五日滑动平均法、相关分析法、回归拟合法，分析了贵州省1980-2020年辣椒适宜移栽期和采摘期的时空分布特征。结果表明：（1）贵州省辣椒适宜移栽期地区差异较大，变化范围为2月27日到5月7日，空间分布存在明显的区域差异，呈自西北向东南逐渐递减的趋势，其主要原因是海拔高度差异较大。近40年移栽期随时间变化，所选的8个站点中，一半站点通过了水平为0.05的显著性检验，分别为：罗甸、榕江、威宁、毕节。（2）贵州省辣椒采摘期地区差异较大，变化范围为9月26日到12月6日，空间分布存在明显的区域差异，呈自西北向南逐渐递增的趋势，其主要原因是海拔高度差异较大。近40年采摘期随时间变化，所选8个站点里，只有2个站点通过了水平为0.05的显著性检验，分别为：威宁、毕节。 |

| Abstract: |
| The transplanting period and picking period of pepper are crucial links for the growth and development of pepper. In order to explore the distribution law of the appropriate transplanting period and picking period of pepper, this paper uses the daily average temperature data of 84 national conventional ground observation stations in Guizhou Province from 1980 to 2020, and based on the five-day sliding average method, correlation analysis method and regression fitting method. The temporal and spatial distribution characteristics of suitable transplanting period and picking period of pepper in Guizhou province from 1980 to 2020 were analyzed. The results showed as follows: (1) The suitable transplanting period of pepper in Guizhou province varied greatly from February 27 to May 7, and the spatial distribution showed obvious regional differences, gradually decreasing from northwest to southeast, which was mainly due to the large difference in altitude. In the past 40 years, the transplanting period changed with time. Among the 8 sites selected, half of them passed the significance test with the level of 0.05, namely Luodian, Rongjiang, Weining and Bijie. (2) The picking period of pepper in Guizhou Province had great regional differences, ranging from September 26 to December 6, and the spatial distribution showed obvious regional differences, gradually increasing from northwest to south, which was mainly due to the great difference in altitude. In the past 40 years, the picking period changed with time. Among the 8 selected sites, only 2 sites passed the significance test with a level of 0.05, namely, Weining and Bijie. |
