摘 要:以幼龄茶园为研究对象,设置行间铺草+防风障、搭建小拱棚、行间铺草3个处理,以裸地为对照,测定各处理下的土壤温湿度、空气温湿度及光照强度等指标。结果表明,各处理均可降低茶园土壤温度的变化、减少土壤表面水分的散失,维持冬季茶园较高的空气温度和空气相对湿度。其中以搭建小拱棚的防护措施对幼龄茶树的保护效果最好,试验期间其土壤含水量较对照提高6.28%,地表最高温较对照提高9.4℃,光照强度较对照降低14.63%,茶园空气温度和空气湿度分别提高3.8℃和26.35%。防风障+行间铺草和行间铺草的效果差异不显著。With open field as the contrast,three treatments including straw mulching plus windbreak,low plastic tunnel,and straw mulching were designed to study their effects on the eco -environment indicators such as soil temperature and moisture,air temperature and humidity,and illumination intensity in infancy tea garden during winter.The results showed that all the three treatments could reduce the variation of soil temper-ature and the loss of soil surface water,and maintain higher air temperature and humidity in tea garden during winter.Low plastic tunnel had the best effect.Compared to the contrast,the soil temperature improved by 6.28%,the highest soil temperature improved by 9.4℃,the air temperature and humidity increased by 3.8℃ and 26.35% respectively,but the illumination intensity decreased by 14.63%.There were no signifi-cant differences between straw mulching plus windbreak and straw mulching.
