In order to estimate the evapotranspiration during the day from the canopy temperature, wheat (winter) and mungbean (summer) were tested during the growth period, and the canopy temperature was measured at any time between noon and 2 pm. n Day observations show that crop evapotranspiration during the day can be estimated using canopy temperature alone, which is 27% (lower) than the wave-to-temperature ratio method. The regression equation between the daytime crop evapotranspiration and the estimated daytime crop evapotranspiration estimated by the wavewise ratio method is ET. Suitable for good irrigation of wheat and mung bean in New Delhi. The crop canopy temperature gauge can determine the canopy of a crop and effectively analyze its transpiration.
Secondly, crop evapotranspiration (ET) needs to be estimated in planned irrigation, production forecasting, and water resources management for better crop yields. Although energy balance-wind ratio method, aerodynamic method, and combination method can better estimate crop evapotranspiration, some field observations are needed. Rapidly-developed remote sensing technology makes regional ET estimation easier. Just the canopy temperature. The temperature, canopy temperature, and leaf temperature difference at noon during the observation period are listed in Table 1. Eight observations of wheat included the main growth stages: seedling stage, flowering stage, early waxing stage, late wax stage, and three-day observation period in summer. They are in the flowering, binding, and maturation stages of mung bean. During the observation period, the leaf area index of wheat and mung bean were within the range of 5.2~6.1 and 2.3~5.7, respectively. The percentage of net thermal radiation accounted for net radiation is listed in the table. The cumulative soil heat flux of the two crops is 1 to 6% of the net radiation during the day, and 8 to 10% of the net radiation in the initial stage of crop growth, and the soil at noon. The percentage of heat flux to net radiation is also within this range.
The results of the crop canopy temperature measurement instrument compared daylight evapotranspiration (ET;) estimated using the canopy temperature and daytime evapotranspiration (ET.) estimated by the wave-temperature ratio method. Although the soil heat flux in the equation was omitted, it did not seriously affect the accuracy of the ET estimate because the measured canopy was intact and the soil heat flux was less than 10% of the net radiation.
