| 摘 要： | 探明红壤旱地花生进行稻草覆盖的最佳时期。通过设定播种后1 d（T1）、出苗后10 d（T2）、始花期（T3）、盛花期（T4）、结荚期（T5）开始覆盖稻草5个处理，以全程无覆盖（CK）为对照，研究覆盖时期对花生产量形成及旱地生态的影响。花生出苗前稻草覆盖会显著降低花生的出苗率，降低产量，而出苗后10 d到结荚期进行稻草覆盖均可以有效的抑制杂草发生，保持土壤水分、降低土壤温度，并有利于减缓花生叶片的衰老，增加后期绿叶数，延长花生叶片的功能，促进根瘤生长，有效的提高花生产量。江西红壤旱地花生稻草覆盖可减少杂草的发生、改善土壤温湿条件，有利于产量形成，适宜的覆盖始期为齐苗后10 d左右，过早或过迟进行覆盖，效果均受影响，甚至会减产。
