Analysis of Ground Temperature in Zhuxi County in 2016 and Suggestions for Transplanting Period of Flue-cured Tobacco
[Objective] To explore the soil temperature changes at different altitudes of tobacco growing areas in Zhuxi County during the transplanting period,and to make suggestions for the best transplanting period of flue-cured tobacco.[Method] A total of 1 281 geothermal data in 9 elevations of 5 towns in Zhuxi County were selected and analyzed.[Result] The temperatures of altitudes at 700 and 800 m reached 16-18 ℃ on April 22nd,the temperatures of altitudes at 900,1 000,1 100,1 200,1 300,1 400,1 500 m reached 16-18 ℃ on April 28th.[Conclusion] Tobacco transplanting could be carried out at the altitudes of 700 and 800 m on April 22nd,and the wastes of heat resources lasted for 13 d;tobacco transplanting could be carried out at the altitudes of 900,1 000,1 100,1 200,1 300,1 400,1 500 m on April 28th,and the wastes of heat resources lasted for 17 d.
