| 摘 要： | 通过对免耕覆盖条件下土壤温度的研究,揭示了该条件下土壤温度的变化特点。试验表明,免耕覆盖的土壤温度不利于豌豆的出苗,且土壤热通量明显小于其它耕作方式。但其土壤温度日变化显示,该方式的下层土壤温度不易受太阳有效辐射的影响。同时,免耕覆盖下的土壤温度影响到作物干物质的积累。

| Abstract: | By studying on soil thermal effects under No-Tillage with Sraw mulch(NTS),regulation of soil temperature variation was obtained.The trial test indicated that NTS was unfavorourable for seed emergence and the soil heat flux was lower than the other tillages obviously.Subsoil temperature variation under NTS was insusceptible by solar effective radiation through analysis on diurnal temperature data.Meanwhile,the soil temperature under NTS affected the dry material accumulation of the crop. |
