为发展农业节水灌溉,利用根据土壤水分湿度进行灌溉的原理,通过土壤湿度传感器控制电流开关对灌水量进行调节,设计了一套自动控水灌溉系统,应用该控水灌溉系统进行田间试验。结果表明,其能够根据田间土壤湿度进行自动灌溉,实现无人值守式灌溉;与常规灌溉相比,自动控水灌溉系统对水稻全生育期每平方米灌水量减少0.191 6 m~3,可增加水稻产量0.170 4 kg/m~2。自动控水灌溉由于无水层淹没土壤,增强了土壤的透气性,同时又能保证土壤水分含量,对水稻分蘖期产生有益的促长作用,使水稻分蘖数增加,进而提高产量。自动控水灌溉是根据作物根系对土壤水分需求进行的高精准灌水,是一种较好的节水灌溉方法,对未...

For the development of agricultural water-saving irrigation, the irrigation aecording to the principle of soil moisture and humidity, the soil moisture sensor to control the current switch to irrigation quantity adjustment, design a set of automatic： control irrigation system, the application of the field experiments were carried out to control irrigation system. The results showed that using this system of water conservation to experiment in field which could do automatic irrigation, thus the unmanned to admit. By the study of experiment to c...
