对引进草坪草在青海西宁地区的种植品质评价

Quality evaluation of several introduced turfgrass varieties in Xining

通过对巴林、亨特、白宝、首相、百琪、百绿、凌志和维加斯8个引进草坪草品种的品质评价,研究了其在西宁地区的坪用性表现以及适应能力,选择出品质较优良的品种。测定了各品种的密度、盖度、质地、耐磨度、颜色、生育型和生长速度以及越冬力。结果表明,供试8个品种中的巴林、亨特、百琪、凌志和维加斯5个品种有较好的越冬能力(Wh≥3)。而8个品种均表现出良好的坪用性(TPP1或TPP2≥3),其中,巴林(Wh=5,TPP1=3 6,TPP2=3 7)、亨特(Wh=5,TPP1=3 4,TPP2=3 6)、百琪(Wh=4,TPP1=4 1,TPP2=3 5)、凌志(Wh=4,TPP1=3 0,TPP2=3 5)和百绿(Wh=3,TPP1=4 0,TPP2=3 1)5个品种无论是越冬力还是坪用性均表现突出,可以作为当地品质较优良的草坪草。

Quality evaluation of eight introduced turfgrass varieties were conducted in Xining Their adaptability and turf performance (TP) including density, cover, texture, growth speed, color, wear tolerance and winter hardness (Wh) were measured The results indicated that the adaptablity of 5 varieties were better than another three (Wh≥3), all the varieties performed well in terms of turf usage (TTP1 or TPP2≥3) Balin (Wh=5, TTP1=36, TPP2=37), Huntsvilla (Wh=5, TTP1=34, TPP2=36), Bargena (Wh=4, TTP1=41, TPP2=35), Barlexas(Wh=4, TTP1=40, TPP2=31) and Bargreen (Wh=3, TTP1=41, TPP2=35) not only adapted well to the environment but also gave good performance, and can be extended in Xining 
