Soil Cover With Organic Mulch and Its Influences on Soil Physical Parameters (Ⅲ)——Soil Temperature Regime Under Organic Mulch

Through field experiment the paper analysed the changes of soil temperature under covers with different thickness of organic mulch and the results were compared with control without cover. The experiment results showed that the daily maximum and daily mean value of soil temperature were decreased, the daily minimum of soil temperature was increased in comparison with control.
