Embodiment 1

[0019] Select CO 2 The concentration is 450mg / L to test, CO 2 The color of the concentration test solution is wine red.

[0020] 0.0001mol / L NaHCO containing 0.05 grams of phenol red indicator per liter 3 Pour 50ml of the solution into a wide-mouth container and place it in the facility environment. After 30 minutes of reaction, observe the color of the test solution. If it is wine red, it means that the CO in the facility environment 2 The concentration is 400-500mg / L. At the same time, according to the effect of the crops grown in the facility on CO 2 Concentration requirements to determine if CO should be administered in a timely manner 2 Gas fertilizer and application concentration.

Embodiment 2

[0022] Select CO 2 The concentration is 570mg / L to test, CO 2 The color of the concentration test solution is red.

[0023] Add 0.002 mol / L NaHCO containing 0.1 gram of phenol red indicator per liter 3 Pour 50ml of the solution into a wide-mouth container and place it in the facility environment. After 20 minutes of reaction, observe the color of the test solution. If it is red, it means that the CO2 in the facility environment 2 The concentration is 500~600mg / L. At the same time, according to the effect of the crops grown in the facility on CO 2 Concentration requirements to determine if CO should be administered in a timely manner 2 Gas fertilizer and application concentration.

Embodiment 3

[0025] Select CO 2 The concentration was 670mg / L for testing, CO 2 The color of the concentration test solution is orange.

[0026] 0.005mol / L NaHCO containing 0.5g of phenol red indicator per liter 3 Pour 50ml of the solution into a wide-mouth container and place it in the facility environment. After 60 minutes of reaction, observe the color of the test solution. If it is orange, it means that the CO in the facility environment 2 The concentration is 600-700mg / L. At the same time, according to the effect of the crops grown in the facility on CO 2 Concentration requirements to determine if CO should be administered in a timely manner 2 Gas fertilizer and application concentration.

Abstract

A method for quickly detecting CO2 concentration in agricultural device includes preparing CO2 test liquid and colorimetric card, filling prepared test liquid in said device for reaction of 20 ¿C 60 min. then comparing it with prepared colorimetric card for obtaining current CO2 concentration in said device.

Description

technical field [0001] The present invention relates to a CO 2 The invention discloses a method for quickly measuring concentration, which belongs to the field of agriculture. Background technique [0002] Facility agriculture is an agriculture that has certain facilities, can improve or create environmental meteorological factors in a local area, and provide good environmental conditions for the growth and development of animals and plants for effective production. It includes facility cultivation and facility breeding, which is one of the most dynamic industries in the world today, and has become one of the important technical means used by countries all over the world to provide fresh agricultural products. At present, facility agriculture in developed countries has formed a complete set of technologies, complete facilities, production specifications, output and quality assurance systems, and is developing towards high-level, high-tech, automation, and intelligence.
