Pipeline irrigation oxygenation controller

Abstract

The invention relates to a pipeline irrigation oxygenation controller which is designed by utilizing a venturi tube principle. The pipeline irrigation oxygenation controller is provided with a water pipe, wherein a venturi tube section is arranged at the middle part of the water pipe, a one-way air inlet pipe is connected to the lateral wall at the neck mouth of the venturi tube section, a filtering membrane is arranged at an air inlet of the air inlet pipe, and an air regulating valve is arranged at the tail end of the air inlet of the air inlet pipe. The controller can automatically add oxygen (gas) into the water pipe according to the velocity of water flow in the pipeline, enables the oxygen to enter the root part of crops along with water flow, effectively prevents the generation of root oxygen deficiency of crops and increases soil respiration. The invention has low manufacturing cost, scientific and reasonable structure, and convenient operation and use, is suitable for crops in greenhouses, vinyl houses and land fields which adopt different pipe diameters of subsurface drip irrigation devices, membrane drip irrigation devices, infiltrating irrigation devices, and the like and also suitable for fishpond oxygenation, and can implement accurate irrigation and improve energy-saving and water-saving effects as well as the yield and the quality of crops.

Description

technical field [0001] The content of the present invention belongs to the technical field of agricultural irrigation equipment, and relates to a pressurized pipeline irrigation or pressurized pipeline water delivery equipment, especially a pipeline irrigation oxygenation control equipment, and its products are suitable for film drip irrigation, underground drip irrigation, seepage irrigation and fish Pond oxygenation and other operations have the effects of energy saving, water saving, increasing air and oxygen, improving soil respiration, increasing air and oxygen in fish ponds, and increasing crop yields. Background technique [0002] my country is a country that is relatively short of water resources in the world. The per capita possession of water resources is only equivalent to 1 / 4 of the world's per capita possession. In many areas in northern my country, the phenomenon of water shortage is even more serious. The development and application of technology is very import...

Problems solved by technology

Because irrigation is to inject water into the soil to increase the soil moisture content, so that the soil moisture reaches the field water holding capacity or even reaches the saturated water content, so that the moisture will discharge the air in the soil, so that the oxygen content in the soil is reduced or even zero, resulting in Hypoxia in the roots of crops, which in turn causes root death, reduces crop biomass and yield, and reduces crop quality

Mulch-film drip irrigation, subsurface drip irrigation and infiltration irrigation are currently the most water-saving and energy-saving fine irrigation new technologies. They are very suitable for growing economic crops such as fruit trees, vegetables, and cotton in greenhouses, greenhouses, or open fields. They have been applied in many areas of China, but There are still some defects, which can be summarized as follows: ①. Drip irrigation, infiltration irrigation and subterranean drip irrigation are small-quantity and high-frequency irrigation technologies, which are also easy to cause the roots of crops to be in a state of hypoxia, and then cause crops to die. Root hypoxia is even more serious; ②, drip irrigation, infiltration irrigation and underground drip irrigation technology are limited in many areas, and the cost is high, farmers are unwilling to accept
