丰收布是一种化纤不织布。它具有保温性能,早春应用于茶树覆盖,能使茶芽提早萌发。利用它的颜色进行茶树遮光,对提高绿茶品质具有较明显的作用。 一、试验材料及方法 我们选择常规栽植密度的本地群体种丰产茶园,用黄色丰收布直接覆盖在茶蓬上。每天日出前盖,日落后揭。阴雨天不盖。小区面积为20×1.5米,重复3次。分别在4月16日、5月28日、6月5日及7月5日按标准一芽二叶采样。用蒸汽进行鲜叶固样。对影响绿茶品质的主要成份氨基酸、茶多酚、咖啡碱、粗纤维等分别进行测定。
Harvest is a chemical fiber non-woven cloth. It has thermal insulation properties, applied in early spring tea tree cover, germination of tea buds can be premature. Use of its color shade of tea trees, to improve the quality of green tea has a more obvious role.
