Hydrogen nanobubble water irrigation device and method

Abstract

The invention relates to the technical field of agricultural irrigation, in particular to a hydrogen nanobubble water irrigation device and method. The hydrogen nanobubble water irrigation device comprises a hydrogen supply system, a hydrogen nanobubble water generation system and a conveying system. According to the device, free gas molecules in irrigation water are promoted to diffuse into hydrogen bubbles through a low-pressure gas-liquid mixing process, then the concentration of hydrogen molecules between water molecule clusters is increased through a high-pressure gas-liquid mixing process, and finally a large number of hydrogen molecules between clusters and hydrogen nano bubbles are reserved in the irrigation water through a pressure reducing device, and the total concentration of hydrogen molecules in the irrigation water is effectively improved; meanwhile, the hydrogen water irrigation effect is further improved by utilizing the characteristic that the hydrogen nanobubbles can penetrate through cell membranes, so that the yield and the quality of crops or commercial crops are improved, the use of pesticides and chemical fertilizers is reduced, and the development of intelligent agriculture and scientific and technological agriculture is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a hydrogen nano-bubble water irrigation device and method. Background technique [0002] In 1964, Renwick et al. discovered the botanical effect of hydrogen molecules early. They found that the germination rate of winter rye seeds was faster after hydrogen molecules were treated. In recent years, the botany effect of hydrogen molecules has become a research hotspot. A large number of research results have confirmed that hydrogen molecules have important regulatory effects on plant physiology: for example, hydrogen molecules have an important impact on the seed germination of various crops, and can effectively reduce the salt stress resistance of crops. , affecting plant flowering time, inducing the expression of antioxidant enzyme gene and heme oxygenase 1 gene, increasing enzyme activity and improving the salt tolerance of rice and Arabidopsis, etc. [0003] In ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, technologies such as hydrogen aeration under normal pressure are often used to prepare hydrogen-rich water for agricultural irrigation. However, due to the presence of a large number of free gas molecules in irrigation water, such as nitrogen molecules and oxygen molecules, they diffuse toward hydrogen bubbles during the aeration process. As a result, the probability of hydrogen molecules entering the water molecules to form intercluster free molecules is reduced, and the hydrogen concentration in the hydrogen bubbles decreases, the aeration effect decreases, and the hydrogen utilization rate is low; at the same time, hydrogen exists in the form of large bubbles, and the residence time in water is short, resulting in Subsequent irrigation lines with low concentration of hydrogen molecules
