摘要:以饲草高粱品种晋牧1号和皖草2号为对照, 在全膜穴播栽培方式下,对6个外引和自育的饲草高粱新品系进行了比较试验。结果表明,各参试饲草高粱新品系在当地均能正常生长及成熟,田间均未发现病害。全年鲜草平均折合产量以JC16-3最高,为118.27 t/hm2,较对照品种晋牧1号和皖草2号分别增产-4.30%、12.37%;全年干草平均折合产量以LC-2最高,为22.60 t/hm2,较对照品种晋牧1号和皖草2号分别增产3.48%、29.14%;LC-1次之,为21.97 t/hm2,较晋牧1号和皖草2号分别增产0.60%、25.54%。综合各参试饲草高粱新品系全年鲜草平均折合产量、全年干草平均折合产量及其农艺性状考虑,认为JC16-1和JC16-3这2个新品系表现较好,全年鲜草平均折合产量分别为115.12 t/hm2和118.27 t/hm2,全年干草平均折合分别为20.73 t/hm2和21.09 t/hm2。虽然这2个品系的全年鲜草平均折合产量和全年干草平均折合产量均低于晋牧1号,但均显著高于皖草2号,在甘肃平凉半湿润偏旱地区种植更具潜力。

Abstract:Taking the wild Lycium ruthenicum from Minqin of Gansu Province as the material, the nutrient contents of water, ash, fat, protein, total axunge, total flavonoids, polyphenol, total anthocyanins and amino acid were determined. The results showed that the cotent of wate was 795 g/kg, ash was 57.254 g/g, was fat 0.490 g/kg, protein was 0.084 83 g/kg, total flavonoids was 25.90 mg/g, total polyphenol was 27.51 mg/g, total anthocyanin was 1.27 mg/g. The total amino acids were 21.33 mg/g, among which seven kinds of essential amino acids accounted for 27.1% of the total amino acids. There were 9 kinds of pharmacodynamic amino acids, accounting for 65.8% of the total amino acids. The content of glutamic acid, aspartic acid and arginine in the pharmacodynamic amino acid is higher, which has higher medicinal value.

饲用高粱(forage sorghum)是禾本科高粱属一年生草本植物, 为普通高粱的一个变种, 具有光合效率高、生物产量高、抗旱、耐盐碱等特点[1 - 4 ],其作为反刍动物的粗饲料在国外已得到广泛应用,但国内研究应用起步较晚。由于干旱地区草食畜产业发展很快,饲用高粱具有抗旱节水、可刈割多茬、收获期灵活、产草量高、特别适宜于青饲、可减少精料、降低成本等特性的品种更受到养殖户的青睐,不仅具有较好的市场开发前景,对草食畜牧业也有较强的支撑作用。……
