摘　　要：以汝城白毛茶幼龄茶树为试验对象,研究高温下遮阴处理对其生长的影响。结果表明,遮阴处理可有效降低汝城白毛茶幼龄茶树的灼伤株率和单株伤叶率,提高幼龄茶树成活率,并降低后期补苗成本。其中,以8针遮阳网遮阴处理效果最显著,汝城白毛茶幼龄茶树灼伤株率和单株伤叶率较不遮阴处理降低57.65、41.77个百分点,成活率提升43.68个百分点,每666.7 m2补苗成本降低58.44%。综上所述,认为在原生境外移植汝城白毛茶幼龄茶树后,加以8针遮阳网进行遮阴处理,可显著提升汝城白毛茶的移栽表现及成本效益。The effect of shading treatment on the growth of'Rucheng Baimaocha'seedlings was studied.The results show that the shading treatment could effectively reduce the burn rate and leaf damage rate of seedlings,improve the survival rate of seedlings,and reduce the cost of seedling replacement in later period.Among them,the shading treatment with 8-needle shading net had the most significant effect.Compared with non-shading treatment,the burn rate and leaf damage rate of seedlings were decreased by 57.65%and 41.77%.The survival rate was increased by 43.68%,and the replacement cost per 666.7 m2 was decreased by 58.44%.To sum up,the transplanting performance and cost-effectiveness of'Rucheng Baimaocha'can be significantly improved by using 8-needle shading net.
