Filtration irrigation method of underground circular artesian spring suitable for trees

Abstract

The invention discloses an underground circular estavel penetration-irrigation method used for trees, which is characterized in that a circular ditch is arranged inside the soil 30cm-100cm in radius range away from the root of the tree trunk; one end of the circular ditch is provided with an estavel protection conversion chamber having the length of 10cm-20cm; an air penetration chamber is arranged above the estavel protection conversion chamber; during the period of installation, the upper end of the estavel protection conversion chamber is 5cm away from the ground surface and an air penetration pipe is higher than the ground surface by 1cm-2cm; the height of the estavel protection conversion chamber is 10cm-20cm and the internal diameter thereof is 5cm-7cm; the water inlet end of the estavel protection device is communicated with the estavel pipe which is connected with a water supply pipe by the micro-pipe; the water outlet end of the estavel protection conversion chamber is connected with the circular water penetration pipe. The method of the invention has the advantages of simple fabrication, convenient construction, low price and high fertilizer utilization ratio. The methodof the invention can prolong the service life of the product from current 6 years to more than 20 years after being used, reduce the irrigation loss by 17%, and improve the fertilization efficiency by 30%.

Description

technical field [0001] The invention belongs to the technical field of orchard irrigation, woodland irrigation and underground liquid fertilization, and in particular relates to an underground annular spring infiltration irrigation method suitable for trees. Background technique [0002] my country is a country with serious water shortage. Arid and semi-arid areas account for 2 / 3 of the total area. Drought and water shortage have not only seriously affected my country's agricultural development but also affected the development of the ecological environment and forestry. Water saving has become an inevitable choice for my country's sustainable development. Therefore, a conservation-oriented society Construction has become China's current and even long-term goal in the future. my country has been exploring water-saving irrigation technology in the history of agricultural development for thousands of years. In the past ten years, my country has developed rapidly in modern wate...

Problems solved by technology

[0003] 1. The drip irrigation pipe (also known as the spring pipe) is buried deep in the ground, and negative pressure forms a backflow after each irrigation. This phenomenon will cause the outlet on the drip irrigation pipe to be blocked, reducing the drip irrigation effect and the service life of the drip irrigation pipe. , replacing the drip irrigation pipe will increase the production cost;

[0004] 2. Buried the drip irrigation pipes in the ground, it can only irrigate one side of the tree root system, and cannot evenly form moist around the tree root system.

At present, the cost of advanced irrigation products has been greatly reduced from foreign imports to introduction, digestion and absorption, and localized production. However, with the increase in the price of petroleum raw materials, it is more difficult to further reduce the price of advanced drip irrigation products. At present, it has begun to show price increases. Therefore, how to find another way to reduce the cost of advanced drip irrigation technology in field application is also a new focus of attention of technicians in the field of irrigation technology
