A device for the local subsurface irrigation
The device is intended for use in crop production on individual HOMESTEAD and garden plots. The device is a vessel that is buried in the ground near the root of the plant. The vessel has in its upper part an opening through which to pour the water, and in the lower part of the one or more openings or pores for water outlet. 2 Il.
A device for the local subsurface irrigation is intended for use in crop production at the individual household and garden areas.
A device for watering plants and soil, called lake [1, s 10, and 11]. The disadvantages of this device are the difficulty of implementation watering plants in accordance with the best standards and significant time spent on watering.
In addition, the known device , consisting of a pipe with holes in which are mounted feeding wicks ended needles, which penetrate near the root of the plant.
The disadvantages of this device are relatively high consumption of materials and sub-optimal watering, so as not monitored live the Wu is chosen as the prototype of the next device [3, S. 81]: “...Take four pieces of pipe with a length of 120 cm each, cut from a half inch pipe five nozzles 15 cm long and drill them in three-millimeter holes. Combining these items, receive a five-meter hose with connections to two edges and three in the middle. One end of the pipe choke tube, and the second free - attached to the water hose. Hose with nozzles placed around the tree. Near each pipe is done well at a depth of 20-30 cm, and, if you need to fertilize the plant, it is placed fertilizer. The water supplied into the well, dissolves them and absorbs into the soil...”
The disadvantages of the above devices are not optimal watering plants, so as not controlled amount of water entering the soil, and low reliability due to the destruction of the wells due to erosion of the walls of the borehole water.
The circuit of the invention is the implementation of irrigation in accordance with the best standards, improving the reliability of the irrigation system and increasing the efficiency of the life of plants.
This goal is achieved by the fact that the proposed device is in the form of the vessel, consisting of two parts: top and bottom, which are connected with ramasa above the earth's surface, is removable and has two holes. Through one hole in the upper part of the vessel nabivayut water, and through another hole aligned with a hole in the bottom of the vessel, the water falls from the upper part of the vessel in the lower part and then into the soil through one or more openings or pores in the lower part of the vessel. This design also creates a new property of the watering device, namely the possibility of increasing the number of stored water as plant growth due to the replacement of the upper part of the vessel at large.
The container may be made from two parts: upper and lower, which are interconnected by means of detachable connections. The lower part of the vessel buried in the ground near the root of the plant, and the upper part above the surface of the earth, is removable and has only one hole in place of the split connection, combined with a hole in the bottom of the vessel. With such design, as the upper part of the watering device becomes an independent vessel, there is yet another new property. Detached from the lower part of the upper part is filled with water near the source of the water delivered to the watering place and attached to the bottom. That is verhneuralskogo subsurface irrigation, made in the form of the vessel, consisting of two parts, where 3 and 4 mating holes in the lower and upper parts of the vessel, respectively, 5 - lower part of the vessel 6 to the upper part of the vessel, 7 - water or nutrient mixture, 8 - hole for water filling. The lower part of the vessel is constantly in the earth, and the top part as plant growth can be replaced by a large increase in the number of stored water.
In Fig.2 shows the device of the local subsurface irrigation, made in the form of the vessel, consisting of two parts. The lower part of the vessel is constantly in the earth, and the top part is a separate vessel, which allows removing the top part from the bottom, fill the top part of the water through the hole 4 near a source of water, and then attach the upper part to the lower part.
The vessel can be made of known structural materials, such as polymers, metals, ceramics, glass, composites.
In the specific example the lower part of the vessel is made of a metal tube of internal diameter 8 mm, outer diameter 10 mm and length 250 mm, One end of the flattened tube so that there is a hole diameter of approximately 0.8 mm to exit the water, and TSA household plastic bottles from 0.5 to 2 liters
Comparative analysis of the prototype shows that the proposed device is different from the prototype: tank above the well in which is stored a supply of water or nutrient mixture; the hard walls of the hole; the hole through which water enters the soil.
These differences allow us to obtain the following results: since the vessel has a fixed volume, it becomes possible to dispense pour water or nutrient mixture and thereby to irrigate on optimal standards; protect the vessel wall hole in the ground where the vessel from destruction, thus achieving higher compared to the prototype reliability; the number and size of holes in the bottom of the vessel, as well as the size of the hole in the upper part of the vessel allow you to adjust the rate of flow of water or nutrient mixture from the vessel, that helps balance the rate of consumption of water by plant roots and the rate of introduction of water into the soil by watering device. When the moisture of the earth occurs locally near the plant roots, which means that plants are created more favorable conditions for growth and development in comparison with the conditions for the growth of weeds, which, increased reliability of irrigation and improved livelihoods plants are obtaining stable and high yields of crops.
