摘　　要：以石羊河下游野生黑果枸杞为研究对象进行平茬处理,经过平茬后3年的连续观测表明平茬后,萌芽时间提前了7天左右,经过3年的生长完全恢复到平茬前的生物量,新萌生的一级分枝平均长度可达70.5 cm,基部直径15.72 mm。同时,分析了平茬黑果枸杞林地土壤水分的变化,表明平茬措施的实施,降低了林地制备对土壤水分的消耗,使平茬区0~80 cm土层3年平均土壤含水率均高于ck。The lower reaches of Shiyang River, the germination time of wild Lycium ruthnicum was advanced about 7 days after the smooth stubble treatment. After three years’ growth, the average length of the new primary branches was 70.5 cm and the diameter of the base was 15.72 mm. At the same time, the change of soil moisture of flat stubble black fruit Chinese wolfberry forest land was analyzed. The results showed that the average soil moisture content of 0~80 cm soil layer in the flat stubble area was higher than that of ck in three years.
