The Correlation between Canopy Leaf-air Temperature Difference and Soil Moisture Content in Different Growth Stages of Grape
摘要
Abstract
In the experimental area of the Xinjiang Uygur Autonomous Region Institute of grape and melon research in 2015-2017,the canopy temperature data in the main growth stage of grape was observed by automatic weather station observation.The meteorological data obtained by synchronous observation and the soil water content (SW) of 0-100 cm were studied.The variation of canopy leaf-air temperature difference (△ T) of grape and its relationship with environmental factors were analyzed.The results showed that the canopy-air temperature difference (AT)between 14:00 in sunny weather was significantly negatively correlated with the soil moisture content (SW) at the depth of 20-40 cm.The correlation coefficient R of the shoot growth period,fruit enlargement period and mature period were-0.87,-0.86 and-0.85,and verified by the measured data of 2017,the measured value (Y) had a good correlation with the simulated value (X),and R were-0.937,-0.860 and -0.899,respectively.Therefore,it can be determined that the root layer of grape was mainly distributed in 20-40 cm soil layer,and the method of predicting the soil moisture in the vineyard by using the canopy-air temperature difference(△ T)measured at sunny day from 14:00 is feasible.关键词
