茶树三年生以前统称“苗期”,此时茶苗根系浅,尤其是无性繁殖的茶苗,根系多伸展在0～15cm土层内,夏秋季节,雨量不足,地面水分蒸发快,根系又吸收不到土壤深层的水分,加之茶苗茎叶幼嫩,水分蒸腾又快,很容易形成旱害,此时应注意抗旱。方法是喷水灌溉,或及早搭荫棚遮荫,或刈割青草 Tea tree three years ago, collectively referred to as “seedling”, at this time tea seedling shallow roots, especially asexual propagation of tea seedlings, the root system more stretching in 0 ~ 15cm soil layer, summer and autumn, lack of rainfall, surface evaporation, Less than the depths of soil moisture, combined with young tea stems and leaves, water transpiration faster, it is easy to form drought, this time should pay attention to drought. The method is to spray irrigation, or shade the shade as early as possible, or cutting the grass
