When the pressure chamber a'nd the thermocouple psychrometer are used to determine water potential of wheat and corn leaves, the values of water potential are basically in agreement, but when they are used to determine water potential of cotton and popular leaves, the values of wheat potential are greatly different, when the dye method is used to deter...

染色法测定玉米叶水势，在高水势时其值比热电偶低，低水势下比热电偶高。虽然三种方法测定值不完全相同，但均随叶片脱水而变化。因此可用它们测定不同条件下叶片水势值的相对变化。

Sanitation detects according to People's Republic of China " public wholesome regulation (GB-9664-85)", guesthouse sanitation standard and public detect operating rules undertakes, testing instrument is: CAnalyzer of O2XH-30112 infrared ray, anemometer of report of form of sound level plan, ventilated psychrometer, hot ball, before the instrument is used all classics calibration.
