| 摘 要： | 为了更好地提高灌木饲料林的经营管理水平,提高其利用率,在过去研究的基础上(李生宝等,1993,王 北等,1992),对饲料灌木树种的特性进行了研究。1 研究地区自然及社会经济概况研究地位于北纬37°47′～38°40′,东径106°42′～107°45′,为宁夏盐池县北部毛乌素沙地西南边缘。干旱少雨,风多沙大,光热资源丰富,年均气温77℃,1月平均气温-89℃,7月平均气温223℃,年温差312℃,≥10℃的积温29449℃,年日照时数28679ｈ,无霜期145ｄ,年降水量250～300ｍｍ,且主要集中在7、8、9几个月,约占全年降水量的60%以上,年变率大于30%,蒸发量是降水量的72倍…

| Abstract: | In order to raise the utilization ratio of forage shrub forest, the characteristics of the shrub species(?ragana intermidia, C.korshinkii,Hedysarum scroparium, H.fruticosum, H.fruticosum Pau. var. Laeve, Atraphaxisbracterate, Tamarix chinensis, Artemisia ordosica%) were studied. the results showed that 8 shrubs can resist the cold or extremely hot weather. Their lateral roots were abundant. Their branches and leaves contained many coarse fat, coarse protein, all kinds of nutrient elements and 19 amino acids. The change law of their yield and the relation between yield and site, density, age, size, cutting were also studied. |
