The water-saving micro-irrigation system has the advantages that a low-pressure pipeline system is used for making drop irrigation water wet the most developed area of a crop root system dropwise, slowly, uniformly and quantitatively so that soil in a main root system movement area of a crop can be kept in an optimal water containing state all the time. Drop irrigation is different from traditional surface irrigation which wets the soil in an all-area mode, and therefore drop irrigation can achieve the effects of lowering irrigation water capacity, promoting crop growth and increasing yield.

A method of determining the surface level of an area subject to flood, furrow or surface irrigation. The method includes the steps of providing at least one measuring cup positioned below the surface level but within the area and providing a water level sensor within or integrated with the at least one measuring cup. The levels provided by the water level sensor are used to calculate the surface level by determining the inflection point between the rapid increase of the monitored levels when the front of irrigation water passes the water level sensor. A further aspect of the disclosure is the provision of a soil moisture sensor, said sensor comprising an auger adapted to be inserted into the ground with minimum soil disturbance, said auger having means for measuring soil moisture.

Most mushroom farmhouses employ surface irrigation for watering, which causes brown spot on mushroom, making the mushroom die or get brown, so cultivated mycelia become broken, preventing continued mushroom farming. In a drip irrigation system, water is flowed through any or both ends of the rubber outer tube (7a), 11a doubly inserted into blade scar of the dripping nozzle (11) or hose (7) only during water dripping, and the rubber outer tube (7a), 11a prevents direct exposure of blade scar to the culture medium layer, not contacting water with external oxygen, thereby preventing mycelia from being coated in the blade scar to clog water hole. Various alien substances are not introduced through the blade scars 6 formed in the flexible soft rubber, and insect control liquid and water is ejected without any clogging by water pressure to ensure effective dripping of water, nutrition liquid and insect control liquid to the culture medium layer of a mushroom cultivating plate.
