摘　　要：在扦插苗圃用不同颜色的塑料薄膜进行覆盖 ,观察地温、气温和空气湿度的变化对扦插苗发根的影响。结果表明 ,用薄膜覆盖的茶苗发根率比对照高十几倍 ,各种薄膜处理的发根效果以黄色膜 >红色膜 >黑色膜 >白色膜 >蓝色膜 ,地温和湿度与茶苗发根的相关系数显著。By covering tea cutting stock with various plastic film and observing the effect of different soil-temperature atmospheric-temperature air-humidity on the rooting of tea cutting. We find that the rooting of tea cutting stock covered with plastic film is increased by ten-times. Moreover, plastic film in different colours varies in its effect on rooting: yellow>red>black>white>blue. The correlation coefficient between soil-temperature air-humidity and rooting is of significant difference.
