The invention relates to agricultural irrigation and can be used in the framework of soil moisture directly to the root area of the plants to ensure cost optimization of water resources, maintenance of the required temperature regime moisture to the root zone, improving the efficiency of delivery of the required spectrum soluble fertilizer, as well as eliminate the possibility of water losses due to evaporation, which in turn prevents the formation of salt crusts on the surface of the earth and creates a favorable air in the soil.
Known dropper, including mounted in the hole of the humidifier housing and mounted therein regulatory element made in the form of a float valve with one upper locking needle in the form of a pyramid on the top surface of the valve and oriented opposite to him a shut-off needle at the bottom part thereof, mating in the initial position of the float valve with outlet openings in the housing of the humidifier and the humidifier has the form of a U-shaped knees, the inner surface each provided with a labyrinth of channels in the form of alternating non-intersecting ridges and troughs, with U-shaped knee is formed by combining parts of the core of permeable material placed in the cavity injector (EN, paten the No. 2214087, IPC A01G 25/02. 2003)
The lack of a dropper is a low degree of operational reliability due to clogging of the holes of the permeable material and the complexity of the design.
The closest technical solution is a device for sub-surface irrigation, including perforated humidifier, characterized in that the humidifier use plastic tube with holes in the bottom, covered with a filter, and a hollow conical tip at the end, with plastic tube installed vertically in place of root mass of plants and serves as a base to which is attached the stem of the plant, the water in it comes from the droppings, which are mounted on a flexible water supply hose (RU, patent No. 2384049, IPC A01G 25/00, 2010).
The disadvantage of this device for sub-surface irrigation is the inability of the temperature control fluid flowing in the root area of the plants, and the low degree of mobility, certain that the water in the device can only come directly from IV, fixed on the distribution pipeline.
The technical result achieved by the present invention is the optimization of costs of water resources, maintaining the desired temperature of the moisture regime of root words is, improving the efficiency of delivery of the required spectrum soluble fertilizer, eliminating water losses due to evaporation, the prevention of the formation of salt crusts on the surface of the earth and the creation of favorable air in the soil. This technical result is achieved by the fact that mobile subsurface humidifier local irrigation (hereinafter "Humidifier") made of removable vodopada capacity, soil injectors with mesh filters and flexible water supply hoses.
