茶叶怎么采摘

合理采摘是茶叶获得稳产、高产、优质的重要措施之一。合理采茶就是要根据茶树品种、气候条件、树龄、生长势及不同肥水水平等因素,结合市场需求采摘茶叶,采茶和留养结合,既收茶叶,又能保证茶树正常生长,达到持续高产优质的目的。

(1)幼龄茶树的采摘:在正常肥水管理条件下,经过两次定型修剪后幼龄茶树,在春茶后期树高可达45厘米以上,经过第三次定型修剪,茶树高达60厘米左右,均可采用“打顶留叶”的方法采荼。其采留标准是春茶留二、三叶,采一芽一、二叶;夏茶留二叶,采一芽一二叶;秋茶留一叶,采―芽一、二叶。在幼龄茶树采摘过程中应注意“采顶养边、采高养低、采密养稀”的原则。经过三次定型修剪和打顶留叶采摘后的幼龄茶树,在树高达60~80厘米,树幅达130厘米左右时,即可用成年树采摘措施管理。

(2)成年茶树的采摘:成年茶树应坚持“以采为主、采留结合、及时开采”的原则,才有可能在较长时间内获得较高的经济效益。春茶采名优茶原料,多为单芽,一芽一叶初展或一芽一叶展,如有5%达到开采标准时即可采茶。采名茶要求原料细嫩匀整,一般采摘一芽一叶初展、一芽一叶展或采单芽。大宗红条茶、绿茶、红碎茶要求原料为中等嫩度,一般以采一芽二、三叶为主及采嫩的对夹叶。打油茶和六堡茶则要求采基本成熟的新梢和对夹二至三叶。一般可采用“全年留鱼叶”或“春、夏茶留鱼叶,秋茶留一叶,及时、分批、按标准采留”的方法采茶。

(3)机械采茶:近年来,在我国大型茶场推广试用的采茶机,有双人担架式、机动型、螺旋滚刀切割式采,茶机及水平旋转刀切割式采茶机两种。这两种采茶机的采摘质量好,操作方便,能适应各种地形的茶园作业,比手工采茶提高工效约10倍。在试用推广采茶机采茶的茶园,其肥培措施也需适当加强。

(4)鲜叶管理:采下的鲜叶及时运到茶叶加工厂,经专人验收后尽快摊放在清洁荫凉的室内。运送鲜叶的容器采用透气性好、清洁的竹编筐,筐的容量以50~100千克为宜,运送途中避免挤压,减少损伤。一般要求鲜叶采摘后4小时内就要进厂,万一不能及时送到茶厂,一定要避免日晒雨淋,并在干净通风处摊放保鲜,然后尽快送往加工厂。
