英国德雷德科公司的园艺家正在研究一种“嫁接”的新方法。它不是把苹果、李等果树的枝条嫁接到其他果树上,而是将它们“嫁接”在由压力输送合成树液的管子上。园艺家们在保持适当的温度和照明的大型无窗建筑物内,由中央控制室通过运输液管向密密麻麻地排列的果树枝条供应合成树液。果树成熟后将实行机械化采摘,或在树液中加入脱落激素进行采收,再用传送带将收获的水果送 Dreidco’s horticulturists in the UK are studying a new method of “grafting”. Instead of grafting branches of fruit trees such as apples and plums to other fruit trees, it “grafts” them on tubes that send pressurized synthetic sap. In a large windowless building that maintains proper temperature and lighting, horticulturists supply synthetic sap from the central control room by transporting liquid pipes to densely arranged fruit tree branches. When the fruit tree matures, it will be mechanized or harvested by adding shedding hormones to the sap, and the harvested fruit will be sent by the conveyor belt.
