摘要 为了选出适宜贵州石漠化地区栽培养羊的饲用木本植物,采集和引进10种植物进行鉴选。经生长性能和适口性等观测,株高、可食产量和冬季移栽成活率的比较,结果为:木豆长势优于其他植物(P<0.05),白刺花和紫穗槐第一年长势差于其他植物(P<0.05);金合欢和木豆的适口性优等,多花木兰和猪屎豆良好,其他植物为中等或中下等;对黑山羊,木豆可食产量居高,多花木兰、金合欢、紫穗槐、山毛豆、猪屎豆和木豆之间无差异(P>0.05)。对白山羊,紫穗槐可食产量居高,猪屎豆、多花木兰、银合欢、木豆、山毛豆、金合欢和紫穗槐之间无差异(P>0.05);紫穗槐移栽成活率最高,但与多花木兰无差异(P>0.05),白刺花低于另两者(P<0.05)。结论:多花木兰、紫穗槐和白刺花可作为贵州石漠化地区栽培养羊的多年生饲用木本植物用种;木豆、猪屎豆、山毛豆和金合欢只能作为一年生用种。 In order to select suitable woody forage plants for cultivation and breeding goats in in rocky desertification area of Guizhou, a series of introduction and collection were carried out and 9 kinds of woody forage plants were selected as samples. The height, edible yield and winter survival rate of transplanting of plants were compared respectively by observing the growth performance and palatability of samples. The results showed as follows: Cajanus cajan (Linn.) MiUsp. (referred to: CCM) was better than other plants in growth period (P〈0.05) , Sophcra viciifolia Benth. (referred to: SVB) and Amorphafruticosa Linn. (referred to: AFL) grew slower than other plants in first year (P〈0.05) ; Palatability of Acaciafarnesiana (Linn.) Willd. (referred to: AFW) and CCM was superior; palatability of Indigofera amblyatha Craib. (referred to: IA C) and Crotalaria mucronata Desv. (referred to: CMD) was good, other plants were middle or inferior; For black goats, the edible yield of CCM was highest, IAC, AFW, AFL, Tephrosia candida DC. (referred to: TCD) , CMD and CCM had no difference (P〉0.05) . For white goat, the edible yield of A FL was highest, CMD, IA C, Leucaena leucocephala (Lain.) de Wit. (referred to: LID) , CCM, TCD, A FW and AFL had no difference (P〉0.05) ; AFL transplanting survival rate was the highest, but no differences for IAC (P〉0.05) , SVB. was lower than the other two (P〈0.05) . Conclusions: IAC, AFL and SVB can be used to cultivate and breed goats in Guizhou rocky desertification area as perennial forage woody plant species; CCM, CMD, TCD. and A FW can be utilized as annual species only.
