坡地茶园普遍水源不足,台湾茶业改良场引进与推广低压式PE孔管灌溉茶园,一般比无灌溉的增产30％以上,效益极为显著。茶园用低压式PE孔管灌溉系统,是以采用管径15厘米(可套接1/2吋PVC塑胶管上)的薄PE软管,管上每40厘米有一喷水孔,孔径0.6厘米,PE孔管以每行茶树下布一条,灌溉时,水由管中出水孔喷出,水柱高 Sloping tea plantations generally inadequate water, the introduction of the tea industry in Taiwan to promote and promote low-pressure PE pipe irrigation tea gardens, generally more than 30% of non-irrigated increase yield, the effect is extremely significant. The low-pressure PE hole irrigation system for tea plantations is based on the use of a thin PE tube with a diameter of 15 cm (which can be sleeved on a 1/2 inch PVC plastic tube). Each tube has a water jet hole of 40 cm, a hole diameter of 0.6 cm, PE hole tube under each tea cloth under a row, irrigation, the water from the tube outlet hole, high water column
