Application of Ground Temperature Thermometer in Management of Ground Temperature in Greenhouse
For greenhouse crop growth, in addition to the obvious influence of atmospheric temperature on its growth, the ground temperature is also a very important factor in determining the quality of greenhouse cultivation. Therefore, in addition to professional temperature sensors, modern greenhouse greenhouse management will be used to detect the atmosphere. In addition to the temperature, geothermal thermometers are also used to strengthen the greenhouse temperature management, and as a basis for effective regulation of the greenhouse environment, to ensure the growth of greenhouse crops meet the standard, increase greenhouse production and quality, improve the economic production facilities of agriculture benefit.
A suitable ground temperature environment is conducive to the growth of greenhouse crops, and promotes the absorption of soil moisture and nutrients by crops to achieve the goal of increasing production and increasing quality. However, if the ground temperature is too low, the growth of greenhouse crops will be inhibited, even if the temperature in the greenhouse is met. The growth of crops will not be too good, which will affect the benefits of greenhouse planting. Therefore, if a ground temperature thermometer is used to manage greenhouse temperature, it is found that the greenhouse temperature is too low, then the following measures can be taken to control it.
1. In winter, keep cold grass, reduce the thickness of permafrost, 2, increase the temperature of warm soil, quicken the land 3, lay the cold grass under the plow layer 4, cover the plastic film on the ground 5, increase the temperature of the nursery bed soil 6, increase the irrigation water temperature, and improve Irrigation technology 7, multi-storage sheds in greenhouses, ridge cultivation 9, maintenance of shed film cleaning 10, biogas emission 11, other methods such as building sheds on leeward sunny slopes, ploughing ploughing, heating of geothermal white dragon pipes, underground Ventilation heating, heap fire, etc.
In general, the low temperature of greenhouses is mostly low in winter. Therefore, in order to ensure the quality of greenhouses in winter greenhouse management, we must use good ground temperature thermometers to strengthen the management of greenhouse temperature, and adopt timely and effective measures to control the ground temperature. The impact of greenhouse crops has been minimized, helping the crops in the greenhouses to survive winters and increasing the overall economic benefits of planting greenhouses in winter.
