陕西引种加拿大杂交高粱、珍珠稷试验研究

Introduction Experiment of Hybrid Sorghum and Pearl Oyster in Shaanxi

[目的]试验旨在研究适宜于陕西地区种植的优质高产的饲草。[方法]于2017—2018年在陕西秦川牛业有限公司杨凌养殖基地牧草种植田进行加拿大杂交高粱、珍珠稷的引种试验。[结果]杂交高粱和珍珠稷生育期分别为83 d、84 d,成熟期分别为114 d、123 d;杂交高粱的干物质、粗蛋白、粗脂肪、中性洗涤纤维和酸性洗涤纤维分别为:16.72%、9.83%、1.25%、61.89%、35.52%;珍珠稷的干物质、粗蛋白、粗脂肪、中性洗涤纤维和酸性洗涤纤维分别为:15.64%、7.63%、0.58%、69.20%、44.07%;杂交高粱青贮的粗蛋白、粗灰分、中性洗涤纤维和酸性洗涤纤维分别为:7.25%、7.69%、67.43%、34.28%。[结论]从播种到收获的整个过程中2种饲草长势良好,均能适应本地区的气候条件,可作为反刍动物优质粗饲料,青贮加工或晒制干草均可。

This experiment aims to study high quality and yield forages which are suitable for planting in Shaanxi. From 2017 to 2018, the introduction test of hybrid sorghum and pearl carp was carried out in the pasture planting field of Yangling Wuquan Town, Shaanxi province, Qinchuan cattle Co., Ltd. The growth period of hybrid sorghum and pearl carp was 83 d and 84 d, respectively;and the maturity was 114 d and 123 d respectively. The dry matter, crude protein, crude fat, neutral detergent fiber and acid detergent fiber of hybrid sorghum were 16. 72%, 9. 83%, 1.25%, 61. 89%, 35. 52% respectively;the dry matter, crude protein, crude fat, neutral detergent fiber and acid detergent fiber of pearl m让es were 15. 64%, 7.63%, 0. 58%, 69. 20%, 44. 07% respectively. The crude protein, crude ash, neutral detergent fiber and acid detergent fiber of the hybrid sorghum silage were 7. 25%, 7. 69%, 67. 43 % and 34. 28%, respectively. The two forages grew well from the sowing to the harvest, and were able to adapt to the climatic conditions of the region. These two forages produced as silage processing or drying hay can be used as a kind of high quality roughage for ruminants (cattle and sheep).
