昭苏地区紫花苜蓿引种品比试验

Experiment of Introduced Alfalfa in Stud Farm of Zhaosu County

2002年和2005年对WL232、苜蓿王、全能苜蓿、费纳尔、阿尔冈金、苜蓿王、新牧1号进行引种试验,并做了品种比较,筛选适合该地生产的优质、高产的苜蓿品种。结果表明:两年平均产量最高的是阿尔冈金,鲜草产量为27033.13 kg/hm2(干:7009.08 kg/hm2),最低的是WL232,为23770.4 kg/hm2(6004.99 kg/hm2)。鲜干比最小的是全能苜蓿3.83∶1,最高的是霍普兰德4.05∶1。陇东苜蓿、霍普兰德、新牧1号、宁夏苜蓿易感病;综合考虑产草量、鲜干比、茎叶比,阿尔冈金、新牧1号、全能苜蓿较好,但新牧1号抗病性较差。

In order to supply forage in cold season, compare to local variety Sc704, the experiment was carried out on 9 introduced species（ WL232, Muxuwang, Quannengmuxu, Feinaer, Aergangjin, Muxuwang, Xinmu No. 1 ） of alfalfa in 2002 - 2005, to select excellent and high yield variety adapted for local area. The results show that the average yield of Aergangjin was the highest in two years, reached 27 033.13 kg/hm^2, And WL232 was the lowest, reached 23 770.4 kg/hm^2. It was the lowest of the ratio of fresh and dry that Quannengmuxu, 3.83 ： 1. and the highest was Huopulande, 4.05： 1. The Longdongmuxu, Huopulande, Xinmu No. 1, Ningxia muxu was easy to be infected with disease. It was synthetically considered that Aergangiin, Xinmu No. 1, Quannengrnuxu was better in the biomass, the ratio of fresh and dry and the ratio of caudex and leaf. But Xinmu No. 1 was easy to be infected with disease.
