黄土高原沟壑区畜牧业的发展,要求提供高产优质的牧草,建立牧草基地。为此,我们在陕西省长武县进行了优良牧草红豆草和早熟沙打旺的引种工作。观测表明,红豆草和早熟沙打旺的越冬率为100%,生长发育良好。红豆草的抗旱性强,含有丰富的营养物质,粗蛋白含量在各个时期均很高,适口性好,是优良的蛋白质饲料;早熟沙打旺产草量要比红豆草高。这两种牧草,尤其是红豆草是很有推广价值的。
The development of animal husbandry in the gully area of the Loess Plateau demanded the provision of high-yielding and high-quality forage grass and the establishment of forage grass base. For this reason, we conducted the introduction work of good forage grass and precocious sand planting in Changwu County, Shaanxi Province. Observations showed that the overwintering rates of sainfoin and precocious sand were 100% and their growth was good. The drought resistance of sainfoin is rich and it is rich in nutrients. The content of crude protein is high in all periods, and it has good palatability. It is an excellent protein feed. The yield of premature safflower is higher than safflower. Both forages, especially sainfoin, are highly promotional value.
