Determination of Carbon Dioxide Increase in Greenhouse
The photosynthesis process of plants is the conversion process of water and carbon dioxide. In order to increase the photosynthesis of plants in greenhouse cultivation, CO2 content is often appropriately increased, and the CO2 content in the air is measured to accurately add or reduce the carbon dioxide content. In this way, the organic matter synthesis of plants is promoted.
Carbon dioxide can be measured with the aid of a carbon dioxide meter or a CO2 recorder. Carbon dioxide is not unlimited in a greenhouse. The main reason is:
1. The photosynthesis of plants is conditional. -----The healthy leaves of plants only use chlorophyll for photosynthesis to absorb carbon dioxide and exhale oxygen when there is a certain sunlight intensity and suitable temperature. Others do not perform photosynthesis. The time of action is to absorb oxygen exhaled carbon dioxide.
2. If excessive carbon dioxide gas is applied within the greenhouse, it will cause plant respiration to be killed by the plant carbon dioxide poisoning.
3, the proportion of carbon dioxide gas is greater than the proportion of air, so carbon dioxide gas will generally be deposited near the ground. The root of the plant absorbs oxygen and exhales carbon dioxide no matter what time it is used. Overdosing will cause the lack of oxygen in the root and death.
It can be seen from the above that increasing the carbon dioxide content is appropriate for plant growth, and vice versa can lead to plant death. Therefore, measuring the carbon dioxide content in a greenhouse with a carbon dioxide meter or a CO2 recorder is necessary to perform an appropriate increase in carbon dioxide.
A Lawn Mower (Mower) is a machine utilizing one or more revolving blades to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine's wheels. Riding mowers, which sometimes resemble Small Tractors, are larger than push mowers and are suitable for large lawns, although commercial riding lawn mowers (such as zero-turn mowers) can be "stand-on" types, and often bear little resemblance to residential lawn tractors, being designed to mow large areas at high speed in the shortest time possible. The largest multi-gang (multi-blade) mowers are mounted on tractors and are designed for large expanses of grass such as golf courses and municipal parks, although they are ill-suited for complex terrain.
