摘　　要：The author made innovation on cultivation technology of Dioscorea oppo- site based on orientation tuberization. According to large furrow, big tuber, and lots of soils, a tuber bed is established suitable for yam growth, and a vertically band- based orientation is introduced. Specifically, soils are ground and colored bands are paved in bottom of furrows where tubers can be cultivated. At harvest, band soils can be removed to collect tubers. It is simple and easy. The yield can be as high as 75 000 kg/hm2. It is applicable in a variety of lands, especially for arid areas, mountains areas or under-forest lands with slopes from 10°to 25°. Semi-mechanical or mechanical planting and harvest can be applied with promising prospects.该文在发明淮山药定向结薯栽培方法的基础上,创新淮山药更为简单易行的新技术;根据淮山药大容沟、大薯床、大土量促进大增产原理,采用建立适合淮山多薯条生长与容纳的大"薯床",研究提出淮山药纵带定向高效栽培新技术,具体为碎土开行(沟)铺设塑料彩布条带或其它淮山薯条生长不易穿透的硬质材料,回土成垄(畦),然后在垄(畦)上种植淮山种薯,采收时将彩布条带上15 cm土壤去掉取薯,简单易行,产量高达75000 kg/hm^2左右;适合于各种土地类型,尤其适合10~25°的旱坡地、山地及林下应用推广;可应用于半机械化或机械化种植、采收,具有重大应用前景。
