80年代以来，我国果树生产发展迅猛，新垦幼龄果园面积占很大比例，而新垦幼龄果园土层浅而瘠、水土流失严重、杂草滋生、管理用工大，严重妨碍果树生产的持续发展。为此，我所经多年研究，培育出匍伏性强、生物量大（单株鲜重500s．以上）、不攀缘、覆盖期长（鲜草期8个月）而 Since the 1980s, the production of fruit trees in our country has witnessed a rapid development. The area of ​​newly reclaimed young orchards accounts for a large proportion. However, the soil layers of newly reclaimed young orchards are shallow and infertile, with serious soil erosion, weeds breeding and large management workers, seriously hinder fruit tree production Continuous development. For this reason, after many years of research, I have cultivated plants with strong creeping nature and large biomass (500 s per plant fresh weight), no climbing, long covering period (fresh grass period of 8 months)
