Photosynthesis is a guarantee of crop yield. That is, plants use sunlight to synthesize carbon dioxide and water into carbohydrates, but the content of carbon dioxide in the air is relatively low, which is not conducive to the increase of crop yields. Therefore, carbon dioxide is added in greenhouses or rate greenhouses. Can greatly increase the output of vegetables. Different plants have different requirements for co2 under different climatic conditions. If the CO2 concentration exceeds the limit, crops will be reduced. Therefore, CO2 detectors should be used to monitor and control the CO2 concentration in the air so as to reach the optimum value.
At present, the existing carbon dioxide detectors at home and abroad are expensive and are not suitable for use by Chinese farmers. To this end, the director of the State Science and Technology Commission Song Jian proposed that as soon as possible to develop a cheap carbon dioxide detector to solve the urgent needs of vegetable production.
The stronger the sunlight, the higher the temperature, the stronger the photosynthesis of the plant, so the more CO2 gas is needed. Therefore, when the sun is strong at noon on a sunny day, the plastic rods have a high degree of overheating. CO2 gas fertilizer should be applied more frequently, and the concentration should be controlled at 1000. Ie between pm. In the morning or in the afternoon, when the sun is weak and the temperature is low in the big urn, CO2 gas fertilizer should be less applied, and the concentration should be between 500 and 500 ppm. On cloudy or rainy days, there is no sunlight. CO2 gas fertilizer should not be added.
According to the demonstration results of CO2 detectors across the country in the past two years, the yield increase of vegetables is significant. Compared with the control amnesty, the average increase of 20% per mu. After using the CO2 detector to monitor the control of CO2 gas fertilizer, the cucumber yield increased by more than 1,500 kilograms. Each year, the plastic scorpion receives at least two dishes, and the room receives at least four dishes. It can increase income by several thousand dollars. In the country, there are at least 10 million rooms and plastic scorpions, and a total of several hundred billion kilograms of vegetables will be produced each year, which will have significant social benefits.
