Generally, a biogas lamp or a biogas infrared furnace is installed in a greenhouse to increase temperature and increase gas fertilizer. In actual production, a biogas lamp or a biogas infrared furnace is generally installed every 50-70 square meters, that is, if The average width of the vegetable greenhouse is 7 meters. It can be achieved by installing one raft every 10 meters. The height of the installation is generally about 2 meters from the ground.
In the actual application process, we should pay attention to the following four aspects:
1. Ignite biogas lamps or biogas infrared furnaces should generally be carried out at a low temperature between 6 am and 8 am, so that the effect of increasing the temperature and increasing the gas is best. It is not recommended to ignite the biogas and gas-enhanced fertilizer when the temperature is high at noon, and it is not suitable to use biogas to increase the temperature and increase the gas fertilizer when the temperature in the greenhouse exceeds 20 degrees Celsius.
2. The time for using biogas to increase the temperature and increase the gas fertilizer should not be too long. After 2-3 hours of ignition per day, the temperature in the greenhouse of the vegetable greenhouse can be increased by 2-4 degrees Celsius, which can effectively prevent the occurrence of low temperature freezing damage of the crops. The carbon dioxide concentration can also meet crop production requirements. If it is ignited for a long time, the concentration of carbon dioxide will continue to rise. If it exceeds a certain concentration, it will affect the normal growth of the crop. Therefore, it is generally suitable to ignite for about 3 hours every day.
3. After the biogas is warmed and the gas is increased, the concentration of carbon dioxide in the greenhouse of the vegetable greenhouse is increased, which is beneficial to the photosynthesis of the crop. On the one hand, the thermal insulation curtain should be uncovered in time to make the crops have sufficient light; on the other hand, the water and fertilizer management should be strengthened and poured in time. Water fertilization, if it can be combined with the application of biogas slurry, the effect will be better, but the biogas slurry must be diluted according to 1:2 water distribution. Generally, the amount of biogas slurry applied once per mu should be controlled at about 500 kg, not too much.
4, biogas to the greenhouse to increase the temperature and increase the gas fertilizer, must undergo strict desulfurization treatment, because the desulfurization is not complete or not desulfurization, will produce sulfur dioxide after combustion, in the case of water vapor will react to form sulfurous acid or sulfuric acid, falling on the leaf surface of the crop It will cause leaf surface burns, which will affect the normal growth of crops and even cause loss of production.
In addition, in the biogas digesters built in greenhouses of vegetable greenhouses, it is not allowed to directly stack the fermented raw materials in the greenhouses in winter. All the raw materials should be put into the biogas digesters to avoid the growth of crops caused by hydrogen sulfide and other gases generated by stacking outside the ponds.
