1.电脑灌溉法国研制出一种由电脑控制的新型“干旱传感器”系统。传感器直接与作物的花、叶、茎相连,能测出它们微细的缩小,从而判定作物脱水程度,并启动自动灌溉系统。仅用4个传感器就能对3ha 的农田或果园进行监测。据法国全国农艺学研究所进行的灌溉试验表明,“干旱传感器”比普通使用的依靠“张力计”来测
1. Computer irrigation France developed a new computer-controlled “Drought Sensor” system. The sensors are connected directly to the flowers, leaves and stems of the crops and their fine narrowing can be measured to determine the degree of crop dehydration and start the automatic irrigation system. 3ha farmland or orchard can be monitored with just 4 sensors. According to the French National Institute of Agronomy conducted irrigation experiments show that “drought sensor ” than the usual use of “tension meter ” to measure
