摘要
1999年1月和12月分别从哈萨克斯坦和俄罗斯引入东方山羊豆种质,1999~2004年的试验研究结果表明:新引1号东方山羊豆干草产量达15525.8kg/hm2,初花期粗蛋白质含量23.88%,氨基酸含量14.17%,种子产量225.1kg/hm2;鲜、干草各类家畜均喜食,分枝期和初花期单宁含量分别为0.02%和0.93%,反刍家畜青饲不会发生臌胀病;种子粒径10~12目,批量种子如混杂菟丝子种子(粒径14~16目)易清选;在积雪覆盖地区-25^-45℃低温下可安全越冬,抗病虫害能力强,适宜在我国干旱、半干旱地区推广种植。
In January and December 1999, the high quality leguminous forage -- Galega orientalis Lain. were introduced from Kazakstan and Russia separately, and the research results （1999-2004） showed that hay yield of Galega orientalis Lam. cv. Xinyin No. 1 can reach 15525.8kg/hm2 , crude protein content was 23.88% at the first-flowering stage, and the content of amino acid was 14.17%. Seed yield was 225.1 kg/hm2, both the fresh and hay are favorite by all kinds of livestock. Tannin content was 0.02% and 0.93% at branching stage and first-flowering stage. No bloating occurred when ruminants were fed. The seed size was 10-12 mu, which is easy to clear up if the hatched seed were mixed with Cuscuta chinensis seed. It can overwinter in the areas covered with snow at --25-45℃. Disease and insect resistance was strong, suitable to cultivate and extend in arid and semi-arid area.
