农田灌溉权威、美国土壤生理学家Claude J.phene把薄塑料管埋在番茄的根系附近,为植物灌溉、施肥,去年每英亩番茄收获100吨(折合32603公斤),打破了大田番茄每英亩75吨的世界记录。 phene的滴灌系统是由计算机随时控制作物的需水量的一种先进方法,灌溉后地表是干的,对许多果实和蔬菜最为适宜,解决了一般灌溉系统由于植物(如甜瓜、西瓜)平卧地表而产生腐烂、污染的弊病,还解决了喷灌或沟渠灌溉不可避免的土壤水分大量蒸发以及因地面不平而灌溉不均匀等问题。
Irrigated farmland, US soil physiologist Claude J.phene buried thin plastic tubing near the roots of tomatoes and irrigated the plants for fertilization. Last year, 100 tons (32,603 kg) of tomatoes were harvested per acre, breaking 75 tons of field tomatoes per acre World record. The phene drip irrigation system is an advanced method of controlling the crop water demand by the computer at any time. The surface of the soil is dry after irrigation, which is most suitable for many fruits and vegetables, and solves the problem of the general irrigation system. Because plants (such as melon and watermelon) The problems of decay and pollution are also solved. Problems such as inevitable evaporation of soil moisture due to sprinkler or ditch irrigation and uneven irrigation due to uneven ground are also solved.
