摘　　要：在黔西北低纬度高海拔地区进行夏秋反季节辣椒育苗。设置8种不同覆盖处理对辣椒育苗出苗影响进行研究。研究结果表明，辣椒育苗A4（播种覆土后盖薄膜，薄膜上加厚度0．8cm麦秸，上部起拱加小拱棚膜，出苗前每天高温期间11：00～16：00小拱棚两端揭开通风）和A6（播种覆土后苗床上加厚度0．8cm麦秸，秸秆上加薄膜，上部加小拱棚膜，出苗前每天高温期间11：00—16：00小拱棚两端揭开通风）处理出苗率达93.49％～96．46％，LSR测验A4、A6均与其他处理达到极显著水平。仪器观测夏秋期间阴天各处理小拱棚内温度和5cm地温变幅不大，温度均在辣椒种子发芽适宜范围内，晴朗天各处理小拱棚内温度和5cm地温变幅大，高温障碍导致种子出苗率下降。Eight coverage methods was used to raise seedling of pepper in summer for cultivation in autum in high-altitude and low-latitude area of Northwest Guizhou. The results indicated that the germination percentage ranged from 93.49% to 96.46% in the treatmentA4 and A6 LSR test. The temperature in the atmosphere and underground 5 cm varied little in the cloudy, day, the temperature was suitable for the pepper seed to germinate, however varied greatly in sundy day among the treatment. Some seed failed to germinate due to high temperature.
