Study on the Period Changing Law of Soil Temperature in Peach Land
摘要
Abstract
[Objective]The aim was to explore the changing law of soil temperature so as to provide basis for regulating the ecological environment of fruit trees manually and diagnosing their life and health situations. [Method] The typical position in peach land was selected and the soil sensors were buried at the depths of 5, 15 and 30 cm under the ground surface for monitoring the changing law of soil temperature in peach land. [Result] In dormant period, the first and second growth periods and growth-cessation period, the daily averages of soil temperature at the depths of 5, 15 and 30 cm were 5.1, 5.4 and 6.0 ℃; 24.3, 23.7 and 23.2 ℃; 24.3, 26.7 and 24.1 ℃; 11.6, 13.8 and 12.7 ℃ resp. In growth-cessation period, the daily falling ranges of soil temperature at the depths of 5, 15 and 30 cm were 0.87, 0.59 and 0.36 ℃ resp. The average soil temperatures at the depths of 5, 15 and 30 cm in winter, spring, summer and autumn were 4.7, 4.0 and 4.3 ℃; 18.9, 16.8 and 16.1 ℃; 25.1, 24.8 and 23.7 ℃; 15.6, 20.2 and 15.9 ℃ resp. All the annual changes of soil temperature at different depths were shown to be symmetric parabola and the highest value of soil temperature occurred in the period from the 140th day to the 220th day in a year approximately. [Conclusion] The continuous changing law of soil temperature in peach land under natural condition was explored preliminarily in this experiment and it provided theoretical basis for regulating soil environment.关键词
