本试验对7种优良牧草的生长物候期、抗逆性、生产性能以及对后作土壤肥力的影响观察测定,结果认为,新疆大叶苜蓿表现最好,适于在南疆地区种植推广,其次是新牧一号苜蓿品种。其它与种牧草品种每公顷产鲜草均高于61500公斤,因而也具有一定的栽培价值。 近年来国内报道了不少优良牧草品种,为了避免象七十年代末全国形成聚合草热那样盲目地引进推广种植,造成不必要的损失,我们于1990年4月至1991年11月在本校牧草试验地进行了牧草引种品比试验,筛选出适合本地栽培推广的优良牧草品种。现将 In this experiment, the growth phenophase, stress resistance, production performance and soil fertility of seven elite forages were observed and determined. The results showed that Xinjiang alfalfa was the best, suitable for popularization in southern Xinjiang, and secondly Is a new animal husbandry, alfalfa varieties. Other and species of forage grasses per hectare are higher than 61,500 kilograms, which also has some cultivated value. In recent years, many excellent domestic forage varieties have been reported in China. In order to avoid blindly introducing and popularizing cultivation like the formation of polymerized grass in the country in the late seventies, causing unnecessary losses, we foraged in our school from April 1990 to November 1991 Experiments were carried out forage introduction ratio test, screening suitable for local cultivation and promotion of fine forage varieties.
