Problems solved by technology

The above-mentioned ways of increasing carbon dioxide all have the problems of unsustainable supply of carbon dioxide and difficulty in controlling the concentration
Using pure carbon dioxide as the gas source and using a gas control valve to regulate the gas supply can ensure controllable and stable carbon dioxide concentration, but its high cost restricts the promotion of this mature industrial technology in the agricultural field

example 1

[0061] Example 1: At 25°C, pure carbon dioxide gas is used to replenish carbon, and the additional application rate is required to be 5g / m 2 .hr, the amount of water entering the photosynthetic zone is V 水 = (5 / 1.5 ) / 0.965 = 3.45 L / m 2 .hr.

example 2

[0062] Example 2: At 25°C, the additional application rate is required to be 5g / m 2 .hr, using power plant flue gas (contains about 13% carbon dioxide) gas source, the required amount of carried water is V 水 = [5 / (0.13×1.5 )] / 0.965 = 26.6 L / m 2 .hr.

Abstract

The invention discloses a method and device for increasing carbon dioxide via agricultural water and belongs to the technical field of agricultural science. The method and device for increasing carbon dioxide employs a law (Henry's law) where carbon dioxide has changes in solubility under different gaseous differential pressures. Carbon dioxide is dissolved in agricultural water first; the carbon dioxide escapes from the solution in gaseous form and is released to the atmospheric environment; therefore, the concentration of carbon dioxide in a plant photosynthetic action region is increased, and synchronous integrated transporting and supplementing of water, gas and fertilizer can be achieved.

Description

technical field [0001] The invention belongs to the field of agricultural science and technology, and relates to a method for increasing carbon dioxide application by using agricultural water for the purpose of improving plant photosynthesis efficiency and a device used. Background technique [0002] Carbon dioxide is the basic raw material for plant photosynthesis to synthesize organic matter, and the carbon dioxide (350-450ppm) contained in the atmosphere supplies the growth of plants in the natural environment. Studies have shown that under suitable conditions such as light, temperature, water and fertilizer, for most plants, the concentration is lower than the saturation point of carbon dioxide, and the photosynthetic efficiency cannot reach the maximum value. Agricultural facilities such as greenhouses create obstacles to the natural supply of carbon dioxide in the environment. In a relatively closed plant growth environment, the lack of carbon dioxide usually becomes t...
