There are many ways to supplement carbon dioxide in greenhouses and greenhouses, such as liquefied petroleum gas, limestone hydrochloric acid, and limestone limestone. Currently, the most common method is carbon hinges and sulfuric acid to produce carbon dioxide. Operation process:
1. Industrial sulfuric acid content of 93% a 980lc, the concentration is too large should not be used directly, before use, concentrated sulfuric acid and water prepared by the volume ratio of 1:3 dilution. Put 3 parts of water into an open plastic bucket (disabled metal container), then slowly pour 1 part of concentrated sulfuric acid into the water along the barrel wall and stir it up with it. It is forbidden to pour water into concentrated sulfuric acid and allow it to cool naturally before use.
2. Weigh a certain amount of carbon hinge into a large plastic container, and add dilute sulfuric acid in divided portions to complete the addition of åœ Bu. The carbon dioxide produced by the reaction is directly diffused into the shed. Observe whether or not bubbles are generated. If bubbles are generated, carbon should be added until no bubbles are generated. Use the waste liquid after completion to dilute water more than 50 times directly for top dressing.
Calculated according to 100 cubic meters of space, to make carbon dioxide concentration to 1000 mg / kg, use 350 grams of carbon, concentrated sulfuric acid 110 grams. A simple device is usually set up at 50 square meters per 40 square meters. The optimum fertilization time for carbon dioxide in the greenhouse should be carried out shortly after sunrise. The specific time is from 9:00 am in November to January, 8 am in February, and 7 am in March to April. When the greenhouse temperature is higher and ventilation is required to cool down, it is stopped for more than one hour before ventilation, and it is cold, cloudy and rainy. Due to low temperature, weak light and low photosynthetic efficiency, it is generally not used. The vegetables can be used in the early and middle stages of growth, but the effect is best when the fruits are rapidly inflated. The fertilization lasts for one month and cannot be stopped halfway, so as to avoid causing premature plant failure, apply more organic fertilizer, deep cultivator, and improve the root environment. Wide distribution of roots improves carbon dioxide fertilization.
After the determination of carbon dioxide content in the greenhouse by using a carbon dioxide recorder, the determination of the amount of carbon dioxide in the greenhouse, as well as the determination of the application time and period is very accurate, so as to ensure the rational use of gas and fertilizer.
An increase in carbon dioxide levels causes a greenhouse effect, and carbon dioxide is the main raw material for photosynthesis during crop growth. The application of greenhouse greenhouses in agriculture is very common nowadays. In order to promote the growth of crops in greenhouses, increase crop yields and growth rates, it is necessary to control the carbon dioxide content in greenhouses. Only the effective monitoring of the gas content in the greenhouse by means of a carbon dioxide recorder can enable timely and appropriate gas and fertilizer applications.
