摘要
平茬对恢复更新腾格里沙漠南缘沙生灌木沙拐枣、沙木蓼和花棒,提高其生长量具有明显的效果,对毛条的恢复有效果,但不十分明显。4种沙生植物的平茬时间应安排在4月中上旬植株尚未萌动以前或正在萌动时隔行或隔株进行,沙拐枣和花棒的留茬高度应选择30或40 cm,沙木蓼的留茬高度应选择20或30 cm,毛条的留茬高度为40或40 cm以上。
Stumping of desert shrubs （Calligonum rubicundum,Atraphaxis bracteata and Hedysarum scoparium） in south margin of Tengger Desert has significant effect on their growth and shows little effect on rejuvenation of Caragana korshinskii. The optimum time of stumping is in the middle and last ten days of April. The optimum height of stubble is 20 cm or 40 cm for Calligonum rubicundum and Hedysarum scoparium, 20 cm or 30 cm for Atraphaxis bracteate, 40 cm or note for Caragana korshinskii.
