摘要: 为了探求鄂尔多斯高原紫花苜蓿土壤温度变化规律,采用HOBOU30小型气象站监测的田间小气候数据,研究紫花苜蓿在第1茬返青末期、第1茬开花期和第2茬开花期的土壤温度的变化规律。结果表明:紫花苜蓿在第1茬返青末期晴朗日的土壤温度呈现正弦曲线的变化规律,土层越深保温效果越好;在第1茬开花期阴雨天的土壤温度呈现自浅向深逐渐稳定的变化规律;在第2茬开花期出现暴雨后5cm处土壤温度的下降斜率与气温接近,但时间滞后约2h;15,25cm处的土壤温度下降斜率相对较低。

Abstract: In order to investigate variation in soil temperature in alfalfa growing in the Ordos Plateau region of northern China,field microclimate data were monitored using an HOBO U30 small meteorological station in alfalfa at the first stage of re-greening,and the first and second stages of flowering.At the first stage of re-greening,on sunny days the soil temperature under alfalfa showed a sinusoidal curve with soil depth;At the first flowering period,on rainy days the soil temperature showed a steady decline with soil depth;The slope of the soil temperature at 5 cm after the rainstorm in the second alfalfa flowering period is close to the temperature,but the time lag is about 2 h;the slope of soil temperature drop at 15 cm and 25 cm is relatively low.

Key words: Ordos Plateau;Alfalfa;Soil temperature
