摘要
农业节水灌溉有三个过程。基于水分亏缺与玉米、柑桔的需水信息,在温室中建立了由微机和作物需水信息控制的节水灌溉控制系统。当作物生长正常时,在温室里得到的节水率为15％～20％。这对未来田间的农业节水灌溉控制系统将是十分有用的。
There are three phases in agricultural water-saving irrigation. On the basis of the corn water stress indes and plant thirst information of corn and orange, the authors establish the water-saving irrigation control system with the aid of a microcomputer and plant thirst information and obtains the water-saving rate 15%~20% for corn and orange under the normal growth condition in green house. It is applicable for agricultural water-saving irrigation control on the field in futrue.
