| 摘 要： | 试验探讨了不同遮荫方式对秋季马铃薯播种及苗期土壤温度和浇水后土壤水分蒸发量的影响.结果表明,播种后垄面覆盖玉米秸、麦秸或与玉米套种都能有效地降低土壤温度.其中垄面覆盖玉米秸的降温效果最好.在8月中旬之前下午5 cm地温平均下降5.8℃,最高下降8.1℃;10 cm地温平均下降4.5℃,最高下降9.6℃.9月中旬以后,随...

| Abstract: | The effects of different mulching methods for autumn potato were studied on the potato sowing,soil temperature at seedling stage and soil water evaporation after irrigation.The results indicated that mulching with corn stalk or wheat straw after sowing and interplanting of potato with maize could effectively decrease the soil temperature,in which,mulching with corn stalk was the best.At the afternoon before middle August,the soil temperature at 5 cm depth decreased averagely by 5.8℃ and maximumly by 8.1℃,while that at 10 cm depth decreased averagely by 4.5℃ and maximumly by 9.6℃.After middle September,the differences of 5 cm and 10 cm soil temperature between the different treatments were smaller and smaller with the decrease of air temperature and illumination intensity.Besides,mulching could obviously decrease the soil water evaporation after irrigation. |
