云南德宏地区5种狼尾草属高禾饲草品种比较试验
Comparative Trial of Five Tall Pennisetum Forage Varieties in the Dehong Region of Yunnan
摘要
Abstract
To select high-stature Pennisetum forage grasses suitable for cultivation in the Dehong region of Yunnan,a one-year variety comparison trial using a randomized block design was conducted with five varie-ties:Pennisetum purpureum Schum.cv.'Taiwan',Pennisetum purpureum Schum.cv.'Dehong',Pennise-tum glaucum(L.)R.Br.× Pennisetum purpureum Schum.cv.'Reyan No.4',Pennisetum purpureum Schum.f.atro purpureum,and Pennisetum giganteum Z.X.Lin.Plant height,tiller number,leaf/stem ra-tio,fresh/dry ratio,yield,and various nutrient components were measured,and the growth performance and nutritional quality of the five varieties were compared.The results showed that the average plant height was highest for P.purpureum cv.'Dehong'(279.82 cm)and lowest for P.glaucum × P.purpureum cv.'Reyan No.4'(250.42 cm).Before the first cut,the tiller number was highest for P.purpureum cv.'Tai-wan'(32.56)and lowest for'Reyan No.4'(20.06).The leaf/stem ratio was highest for P.purpureum f.atro purpureum(1.40)and lowest for P.purpureum cv.'Dehong'(0.73).No significant difference in fresh/dry ratio was observed among the varieties,ranging from 0.14 to 0.16.The fresh forage yield of P.purpureum cv.'Taiwan'was the highest(542.54 t/hm2),followed by P.purpureum cv.'Dehong'(493.91 t/hm2),and both were significantly higher than those of the other varieties(P≤0.01).Among the nutritional components,no significant differences were found in crude fat,calcium,or phosphorus content among varieties(P＞0.05).The crude protein content was highest for P.purpureum f.atro purpureum(10.36％)and lowest for P.purpureum cv.'Dehong'(6.28％).The relative feed value was higher for P.purpureum f.atro purpureum and P.purpureum cv.'Dehong'(75.72 and 74.61,respectively),followed by P.purpureum cv.'Taiwan'(72.39),while P.giganteum and'Reyan No.4'were lower(69.99 and 68.84,respectively).Based on comprehensive evaluation of yield,quality,and adaptability,the recommended order for extension of the five forage grass varieties in the Dehong region of Yunnan is:Pennisetum purpu-reum Schum.cv.'Dehong',P.purpureum Schum.cv.'Taiwan',P.purpureum Schum.f.atro purpu-reum,Pennisetum giganteum Z.X.Lin,and Pennisetum glaucum(L.)R.Br.× Pennisetum purpureum Schum.cv.'Reyan No.4'.关键词
