摘要: 为探索不同施肥措施对土壤温度变化的影响,利用肥料长期定位试验,对10 cm土层的土壤温度进行连续监测,结果表明:10 cm地温的日变化规律呈正弦曲线,不同施肥条件下地温在15:00—17:00达到最大值,7:00—9:00最低。施肥对土壤地温的影响主要是通过影响土壤水分和作物生长产生的间接作用,与对照相比,施肥处理下的地温日平均值及≥10℃的积温均较低,不同处理间的地温日平均值差异在马铃薯块茎增长期最大,NPKM、NPK和M的地温平均值分别比CK低1.7℃、1.3℃和1.1℃;整个生育期内的积温,NPKM、NPK和M分别比CK低86℃、83℃和68℃。

Abstract: To explore the influence of different fertilization measur es on soil temperature change, the 10 cm soil layer soil temperature was continuous monitored in the treatments of NPKM, NPK, M and CK of a long-term fertilization experiment.The results showed that the 10 cm daily variation of soil temperature was sine curve and the soil temperature under different fertilization conditions reached maximum at 15:00—17:00, lowest 7:00—9:00. Compared with the control, the average temperature and accumulated temperature in different fertilization treatments were lower and the differences among them were biggest in the tuber growth period. The average temperature in NPKM, NPK and M were lower than CK respectively by 1.7℃, 1.3 ℃ and 1.1 ℃. The accumulated temperature in NPKM, NPK and M were lower than CK respectively by 86.0 ℃,83.0 ℃ and 68.0 ℃.
