在内陆盐碱条件下进行了NyPa草的引种试验。结果表明:NyPa宽叶品种济南绿期长达10个月,NyPa窄叶近9个月;两品种分蘖繁殖成活率分别达到89.2%~93.3%和97.3%~98.8%,繁殖系数为6.7~31.8;自然生长条件下年生长高度分别达到53.8~67cm;NyPa宽叶品种的年干草产量达到500kg以上。上述结果说明,两种草种具有较强的适应抗逆特性,为内陆水涝和盐碱地优良的生态和经济草种,其中NyPa宽叶绿期长、生物量大,可作为草坪和饲料兼用型草种利用,NyPa窄叶片柔软、叶色鲜绿、分蘖分散性好,可作为草坪草利用。
The introduction experiment of NyPa grass was carried out in inland salinity. The results showed that the broad-leaved NyPa species had a green duration of 10 months and NyPa narrow-leaf species nearly 9 months. The tillering survival rates of the two varieties reached 89.2% -93.3% and 97.3% -98.8%, respectively, and the reproductive coefficients ranged from 6.7 to 31.8 ; The annual growth height under natural growth conditions reached 53.8 ~ 67cm respectively; and the annual hay yield of broad-leaf NyPa varieties reached more than 500kg. The above results show that the two species of grass have strong adaptability to anti-retrogradation characteristics, and are excellent ecological and economic grass species for inland waterlogging and saline-alkali soil. Nypa has a wide green leaf period and a large biomass, and can be used as both lawn and feed Type grass use, NyPa narrow leaves soft, bright green leaves, tiller dispersion is good, can be used as lawn grass.
