一、茶苗遮蔭的重要意义: 茶籽播种后,于春季开始萌芽出土,並逐漸生長。此后進入夏季高溫时期,茶苗生長尚幼,莖叶組織还未充分健全,根系不發达,細根發生極少,遭受夏季强烈日光灼射,天气又是多晴少雨,促使茶苗蒸騰作用加速,土壤呈干旱現象,茶苗根系又不發达。吸收能力不强,水份供应就 First, the importance of tea seedling shade: After sowing tea seeds, germination unearthed in the spring and gradually grow. Since then into the summer heat period, the growth of young tea seedlings is still young, stem and leaf tissue is not yet fully developed, underdeveloped roots, very few fine roots, suffered strong sunlight in summer, the weather is more sunny and less rain, to promote the transpiration of tea seedlings accelerated, The soil is in aridity and the root system of tea seedlings is undeveloped. Absorption is not strong, water supply on it
