摘　　要：以14年生沙棘(Hippophae rhamnoides)为材料,采用机械和人工方式,对其进行留茬高度为-5、0、5和10 cm的平茬试验,测定平茬后沙棘生长指标、健康状况指标和单株产果量。结果表明:留茬高度以0 cm为最佳;在硬梁地上沙棘留茬高度不应超过5 cm;在沙地上,根据生产实际需要,可以进行-5 cm的平茬。Taking 14-year-old raw Hippophae rhamnoides as test material,adopting mechanical and manual as test methods,stumping tests with stubble heights of-5 cm,0 cm,5 cm&10 cm were conducted.The vegetative growth index,health status index&fruit yield per plant of the stubble of Hippophae rhamnoides on hard beam ground should not exceed 5 cm.On sand,according to the actual needs of production,-5 cm horizontal stubble could be conducted.
