Description

Device for increasing oxygen and improving soil fertilizer efficiency of pipeline

Technical Field

The utility model belongs to the technical field of facility crop cultivation, concretely relates to improve pipeline oxygenation of facility crop's soil oxygen content improves soil fertilizer and imitates device.

Background

Water, fertilizer, gas and heat are several important factors influencing the growth of crops, people in facility agriculture pay more attention to the regulation and control management of the water, the fertilizer and the heat, and the factor of the 'gas' is lack of scientific understanding, so the influence of the gas on the growth of the crops is ignored. In fact, during the growth process of crops, the root systems and the blades need to be subjected to aerobic respiration, but the growth environment of the facility agriculture crops is a relatively closed environment, the soil gas content is low, and the root systems cannot fully perform aerobic respiration during growth. Related scholars research the oxygen adding irrigation technology to supplement oxygen content to crop roots so as to solve the problem of lack of oxygen in the roots. The oxygenation irrigation is to provide oxygen to the root system of the crop to ensure the sufficient oxygen content of the rhizosphere of the soil, ensure the optimal growth function of the root, improve the growth environment of microorganisms, facilitate the mineralization and decomposition of organic matters and improve the fertilizer efficiency conversion. It has been reported that an increase in the oxygen content of soil increases the developed biomass of the root system of crops, and the yield increases as the amount of nutrient elements absorbed from the soil increases. The oxygen enrichment of the soil is beneficial to the propagation and growth of aerobic microorganisms, and most of the microorganisms decomposing the organic fertilizer are aerobic or facultative aerobic, so that the oxygen enrichment treatment of the soil can improve the fertilizer efficiency level of the organic fertilizer, reduce the application amount of the fertilizer and promote the good development of the agricultural ecological environment. At present, in facility agriculture, less equipment for carrying out oxygen enrichment treatment on soil is provided, or the oxygen enrichment treatment is carried out by adopting a mode of burying a vent pipe in the soil. For large-scale facility agriculture, the characteristics of oxygen supply insufficiency and the like can be caused by small aeration and air conduction amount of the ventilation pipe.
