Carbon dioxide detector can be widely used in agriculture, aquaculture, industrial fields, such as: planting greenhouses, livestock breeding farms, beer, carbonated beverages, energy-saving environmental protection products, production processes and safe production downhole operations. In our daily life environment such as kindergartens, schools, office buildings, shopping malls, supermarkets, stations, hospitals and other public places, the monitoring of carbon dioxide concentration can improve the quality of air, thereby improving learning and work efficiency; preventing the epidemic of infectious diseases, ensuring Public health and safety. Now we introduce the application of CO2 detectors in agriculture and animal husbandry: press fittings produces accorindg to park ,connex ,vigea and nibco,Approved watermark Press Fittings，press fittings，vigea press fittings，Nibco press fittings Taizhou Runde Company , https://www.zjbrassfittings.com
1. The use of carbon dioxide in planting greenhouses is one of the raw materials for photosynthesis of green plants, and 95% of the dry weight of crops comes from photosynthesis. Therefore, carbon dioxide has also become an important factor affecting crop yields. The cultivation of plastic greenhouses keeps the crop in a relatively closed place for a long period of time. The carbon dioxide concentration in the greenhouse varies greatly within a day and reaches a maximum of 1000 to 1200 pp before sunrise, and drops to about 100 ppm after 2.5 to 3 hours after sunrise. About 30% of the concentration (330 ppm), and it has been maintained until 2 hours after noon began to rise, and returned to atmospheric level around 4 pm. The carbon dioxide concentration required for vegetables is generally 1000 to 1500 ppm. Therefore, the shortage of carbon dioxide in plastic greenhouses is quite serious and has become an important factor affecting the output of plastic greenhouse vegetables. The installation of a carbon dioxide monitor in a plastic greenhouse can ensure that the carbon dioxide monitor can promptly alarm when the concentration is insufficient, thus using gas fertilizer. Ensure that vegetables, edible fungi, flowers, Chinese medicine, etc. are available in the morning, with high quality and high yield.
2, the impact of carbon dioxide on vegetable production According to China Agricultural Information Network reported: cucumber, tomato, summer squash is a common three kinds of vegetables, for this actual situation, in these three kinds of vegetables on the carbon dioxide fertilization experiment, the effect of increasing production is very Significant. Three kinds of vegetables were respectively given a carbon dioxide concentration of 1,000 mg/kg, cucumbers increased by 465.5 kg per 667 square meters, an increase of 27.1 %; tomatoes averaged 410.7 kg per 667 square meters, an increase of 23.6%; and zucchini increased by 373.2 kg per 667 square meters. , Increase production by 21.9%.
3. Effect of Carbon Dioxide Application on the Characters of Vegetable Plants After application of carbon dioxide in plastic greenhouse vegetables, the plant traits were significantly better than those without carbon dioxide. After cucumbers were treated with carbon dioxide, the plants grew well. Plants that were applied were 15-20 cm more than those that were not applied. They were 2-3 leaves longer and the leaves were significantly larger and thicker. The leaf area per plant was 0.19-0.3 square meters, which was earlier than 2 plants. Nodes are melon-fruited, and the fruit setting rate is high. The number of single plants is 3 to 5, and the melon strips are dark green, and the top 4 to 5 cm of melon strips are yellow. Moreover, the application of carbon dioxide gas fertilizer can also enhance the plant's ability to resist cold and disease. After applying carbon dioxide to tomatoes, the plants increased significantly, the thick green leaves became thicker, the fruits matured earlier, and the fruit surface became bright. The change of the long phase of the carbon dioxide in the zucchini was significantly greater than that of the non-application of the zucchini. The applied leaves were hypertrophic, the stem was thick, the plants were large and strong, and the non-applied plants were small and weak. And Shi's performance was early.
