1自动灌溉在果树果枝等部位安置一些特制的触角,以测试作物的细微变化。当作物不能从土壤中获取水分,必须消耗本身果枝的水分时,作物茎秆或果枝就会出现外形缩小的迹象,触角便能立即将其译成信号传给计算机,计算机便启动灌溉装置进行灌溉。2负压差灌溉将多孔的管道埋入果园地下,依靠管中水与周围土壤产生的负压差进行自动灌溉。整个系统能根据管四周土壤的干湿程 1 Automatic irrigation Set some special antennae in fruit tree branches to test subtle changes in crops. When the crop can not get the water from the soil and must consume the water of its own fruiting branch, the crop stem or fruiting branch shows signs of shrinkage. The antennae can immediately translate it into a signal to the computer, and the computer starts the irrigation device for irrigation . 2 Negative pressure difference irrigation Porous pipe buried in the orchard underground, rely on water pipe and the soil around the negative pressure difference generated by automatic irrigation. The entire system can be based on the soil around the tube dry-wet process
