Double-air-pressure balance pipe type soil-moistening water-saving irrigator for plant cultivation

Abstract

The invention discloses a double-air-pressure balance pipe type soil-moistening water-saving irrigator for plant cultivation. The double-air-pressure balance pipe type soil-moistening water-saving irrigator is provided with a water storage device, a water soaking conical head, a soil moistening device, a built-in air pressure balance pipe, a dustproof cover, a sealing plug, a soil moistening device side opening, an external air pressure balance pipe and a soil moistening device exhaust hole; and the external air pressure balance pipe is inlaid in a pipe inlaying groove. The built-in air pressure balance pipe penetrates through the sealing plug, an upper end opening g of the built-in air pressure balance pipe is exposed out of the sealing plug, a lower end opening o of the built-in air pressure balance pipe extends to the bottom end of the water storage device, when water seeps out of the water soaking conical head, vacuum is formed at the top of an inner cavity of the water storage device, and the water seepage speed and the water seepage amount are controlled under the external atmospheric pressure. The soil moistening device exhaust hole is formed in the side wall of the soil moistening device and connected with the external air pressure balance pipe, and gas generated in the soil moistening device is exhausted in time. When the irrigator is inserted into soil for hilling, the soil moistening device can be filled with soil, and water can be slowly released into the soil moistening device, is conserved in the soil moistening device, is uniformly infiltrated in the surrounding soil space and is fully absorbed by plants.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a soil-moistening and water-saving irrigator with dual air pressure balance tubes for plant cultivation. Background technique [0002] Large-scale plant cultivation is carried out every year all over the world. Irrigation is a necessary measure to ensure the survival of cultivated plants. At present, the traditional methods of watering and irrigation for plant cultivation are carried out in an open environment, and repeated watering and multiple watering are required. Water, plenty of water. Due to the serious transpiration and leakage in the open environment, and the compacted soil is not easy to irrigate, a large amount of water resources evaporate, leak and lose, and the utilization rate of water resources is extremely low, resulting in a large amount of waste of water resources. In order to improve the utilization rate of water resources, people adopt measures such...

Problems solved by technology

Due to the serious transpiration and leakage in the open environment, and the hard soil is not easy to irrigate, a large amount of water resources evaporate, leak and lose, and the utilization rate of water resources is extremely low, resulting in a large amount of waste of water resources

In order to improve the utilization rate of water resources, people adopt measures such as hydroponics, water pits, high soil cultivation, and even drip irrigation and micro-spraying. However, since the production is carried out in an open environment, the evaporation and leakage of water resources cannot be controlled. , loss, water resource utilization effect is very unsatisfactory
