茶树密植免耕是指在一定土肥水条件下,采取宽幅均衡密植,使茶丛群体在2—3年内复盖整个地面,然后停止一切耕锄。 它的特点是成园快,产量高,有利于加快茶叶的生产。过去的茶园因种植稀,新植园一般需经4—6年才能投产(亩产只有几十斤),10年以上方可高产。由于成园慢,投资年限长,前期产量低,故在相当程度上影响了群众发展茶叶生产的积极性,难以做到幼龄期的正常抚育,前期管理不善,后期企望稳产高产也往往落空。密植免耕法正好克服了旧式种茶法的积弊。我所1975年种植的密植免耕茶园1976年亩产级内干茶即达170
Tea tree planting no-tillage refers to a certain soil and fertilizer conditions, to take a wide range of close planting, so that tea clumps cover the entire ground in 2-3 years, and then stop all farming hoe. It is characterized by fast-growing garden and high output, which will help to speed up the production of tea. In the past due to the cultivation of rare tea plantations, plantations generally take 4-6 years to put into operation (only a few kilos per mu yield), more than 10 years before high-yielding. Due to slow growth, long investment period and low production in the early stage, it has affected the enthusiasm of the masses in developing tea production to a certain extent, and failed to achieve the normal tending in early age. The previous period was poorly managed. Close planting no-tillage just overcome the shortcomings of the old method of planting tea. In 1975, I planted no-tilled tea plantation in 1976, dry-weight tea production that is up to 170
