美国籽粒苋是一种高蛋白多用途饲料作物,根据我们的栽培试验表明,美国籽粒觅植株高达3.4m,亩产鲜草0.74万公斤。亩产籽种588公斤。美国籽粒觅花期营养价值最高,粗蛋白含量17.5%。粗纤维16.71%,比其它牧草都低。通过奶牛饲喂试验,试验组比对照组,奶牛日均增奶无显著差异。由于美国籽粒觅生长期短,在水肥条件好的情况下,能获得高产,因此适宜在甘肃河西三地区武威、张掖、酒泉和一些灌溉条件较好的川水地带大面积推广种植,特别是在小麦收割前后,进行套种、复种,效益更好。
American amaranth is a high-protein multi-purpose forage crop. According to our cultivation tests, the U.S. grain seeks plants up to 3.4 m and the yield of fresh grass is 0.74 million kg. 588 kilograms per mu of seed. The highest nutritional value of the United States at the floriculture of the United States, the crude protein content of 17.5%. Crude fiber 16.71%, lower than other pastures. Through the dairy cow feeding test, the experimental group than the control group, no significant difference in the average daily milk of dairy cows. Due to the short growth period of the United States, the high yield can be obtained under the condition of good water and fertilizer, so it is suitable for large-scale popularization in Wuwei, Zhangye, Jiuquan and some well-irrigated areas in Hexi, Gansu Province, especially in the Wheat before and after harvest, intercropping, multiple cropping, better efficiency.
