Plant root system and ventilation sand bag infiltrating irrigation system

Abstract

The invention relates to the technical field of the plant root irrigation and in particular to a plant root system and ventilation sand bag infiltrating irrigation system. The plant root system and ventilation sand bag infiltrating irrigation system comprises a water supply capillary pipe, an annular branch pipe and a ventilation sand bag. A water inlet of an air doping chamber of the ventilationsand bag is communicated with the annular branch pipe. The air doping chamber is internally provided with an air doping blade. The upper end of the air doping chamber is further communicated with a ventilation pipe. A water seepage chamber comprises a coarse sand layer, an intermediate sand layer and a fine sand layer. The coarse sand layer and the intermediate sand layer are separated by a firstsand net. The intermediate sand layer and the fine sand layer are separated by a second sand net. A third sand net is installed outside the fine sand layer. A mesh diameter of the first sand net is less than a sand diameter of the intermediate sand layer. The mesh diameters of the second sand net and the third sand net are less than the sand diameter of the fine sand layer. The plant root system and ventilation sand bag infiltrating irrigation system is capable of carrying oxygen in air into a water flow, increasing dissolved oxygen in water, and according to water content in soil, automatically controlling a water flow rate of the water supply capillary pipe.

Description

technical field [0001] The invention relates to the technical field of plant root irrigation, in particular to a plant root system plus aeration sand bag infiltration irrigation system. Background technique [0002] During the growth of plants, the plant roots also need to breathe. Since the roots are buried in the ground, the oxygen required by the roots is mainly obtained from water (dissolved oxygen). However, the amount of dissolved oxygen in normal irrigation water is limited and will be consumed soon. The exhaustion of dissolved oxygen will cause the roots to undergo anaerobic respiration. The alcohol produced by anaerobic respiration has a strong poisonous effect on young roots. If anaerobic respiration is strong , The alcohol produced leads to the death of root cells, that is, root rot occurs. [0003] In order to avoid root rot, there should be sufficient dissolved oxygen in the water. The current method is mainly to increase the frequency of water changes by incr...

AI Technical Summary

Problems solved by technology

The current method is mainly to increase the frequency of water changes by increasing the water consumption rate in the soil and increasing the frequency of watering, so that the roots can continuously obtain oxygenated water, but this phenomenon will lead to excessive watering and cause root accumulation. Water is also unfavorable to the growth of plants. It is necessary to drain the accumulated water in the root system in time. This requires high drainage of the soil and ventilation of the environment. It is required that the soil drainage should be good so that excess water can be discharged in time and the environment should be well ventilated. , to speed up water consumption
