Inside the greenhouse thermometer should be hung in what place?

Hanging in the production of greenhouse vegetables, vegetable farmers within the greenhouse thermometer to take it easy, there will be a thermometer to hang on the wall or under canopy vents, when some vegetables just engraftment, hang a thermometer in the vegetable growing point more than 1 m distance. Once the thermometer to hang in the air vents, ventilation, outside in the cold air into the barn, vents under rapid temperature, if the temperature adjustment according to its vents, inevitably lead to relative high temperature, affect the normal growth of vegetables. Thermometer hang after the wall in the greenhouse, also cannot accurately reflect the temperature of the heat, can not adjust temperature on this basis. Thermometer is hanged in more than one meter distance vegetables growing point, high temperature on the high side, the temperature near the situation is difficult to accurately reflect the vegetables growing point. Therefore, central temperature object is the hanging position of beautiful PengShi, distance vents, door, wall, far distance vegetables growing point 10 centimeters. In order to more accurately reflect the vegetables grow the temperature of the position. In addition, should be in the tent to hang the thermometer, temperature is measured, take the average value, so as to reduce the error, ensure management measures were wrong.
