Automatic oxygen therapy crop waterlogging reduction device based on farmland water level

Abstract

The invention discloses an oxygen therapy device for agriculture, in particular to an automatic oxygen therapy crop waterlogging reduction device based on farmland water level. The automatic oxygen therapy crop waterlogging reduction device based on the farmland water level comprises an oxygen bottle, a water level monitoring device, a first automatic controlling valve and an underground pipeline device. The water level monitoring device is arranged underground, the first automatic controlling valve is arranged at the outlet end of the underground pipeline device, the water level monitoring device is connected with the automatic controlling valve, and the oxygen bottle is connected with the underground pipeline device. The water level sensing portion of the water level monitoring device is arranged near the upper portion of the underground critical depth of water, when a preset oxygen supplying condition is met, redundant water inside the pipeline is discharged, oxygen is transmitted to the root zones of crops automatically, the whole discharge pipeline is aerated, and the oxygen is dispersed to around root zones of the crops through holes on the discharge pipe. The automatic oxygen therapy crop waterlogging reduction device is capable of supplementing oxygen at the root zones of the crops to reduce the stress of waterlogging of crops, recovering vitality of the root zone of the crops, fully-automatic during the whole process of working, and beneficial for popularization.

Description

technical field [0001] The invention discloses an agricultural oxygen delivery device, in particular to a device for delivering oxygen to crops to reduce waterlogging damage under the condition of shallow water level. Background technique [0002] Crop yield loss due to soil waterlogging is a global problem. According to estimates by FAO and the International Soil Research Association, soil with excessive moisture accounts for about 12%, and short-term waterlogging damage due to uneven distribution of precipitation and improper irrigation and drainage is quite common. Waterlogging in some areas has seriously affected the quality, high and stable yield of crops. [0003] The traditional methods of waterlogging and waterlogging reduction mainly use surface or underground ditches, pipeline drainage, or use crop growth regulators, apply organic fertilizers, etc. to reduce crop waterlogging. plant metabolism. The change of oxygen in the rhizosphere profoundly affects the growt...

[0003] The traditional methods of waterlogging and waterlogging reduction mainly use surface or underground ditches, pipeline drainage, or use of crop growth regulators, application of organic fertilizers and other methods to reduce crop waterlogging. plant metabolism

The change of oxygen in the rhizosphere profoundly affects the growth state of plants. How to replenish oxygen in the root zone in time to reduce crop waterlogging stress and restore root vitality after drainage engineering is used to reduce waterlogging has not yet been found in relevant research and its automatic oxygenation supporting devices. to report
