四川群体种茶树机采树冠培育技术研究

GROWING TECHNIQUE OF TEA CROWN FITTING TO MECHANIZED HARVEST FOR THE SPECIES OF SICHUAN POPULATION

为了适应机采需要,对手采的四川群体种茶园,春茶机采后进行重修剪,并配之手采、机采辅助技术,以培育树冠.结果表明:2～3年鲜叶萌发基本整齐,茶树高度适当(为0.60～0.80m)树幅增大25%,小桩数增加36%,鲜叶增产17%,春夏茶品质优良,适合于机械化采摘的要求.

For the reqiurenent of mechanized harvest of tea,a study on the crown growing of Species of Sichuan Populatin was conducted. After the harvest of spring tea,a heavy pruning was adopted, and then used both the hand and mechanized harvest, Such that the fresh leaves of tea sprouted in good order, the height of tea had a proper value of 0. 60-0. 80 m, the tea width was increased by 25%, the amount of branchlets was increased by 36% ,the yield of fresh leaves was raised by 17%. After 2-3 years, both the spring and summer tea had a better quality and the tea bush fitted for mecnanical harvest.
