美国籽粒苋是苋科饲用作物。它育成于美国,1987年引种到中国草业陕西千阳实验点。连续两年的试验研究及推广利用表明:美国籽粒苋适应范围广、抗逆性强、植株高大、生长迅速、产量高、适口性好、营养价值高、各种家畜均喜食。在麦茬地栽培,60～90天的生长时期内,鲜草产量可达3400～7404.4公斤/亩。美国籽粒苋在我国北方一年一熟制地区的小麦连作体系中很有发展前途。
American amaranth is amaranth forage crops. It was bred in the United States in 1987, introduced to the Chinese grass industry in Shaanxi Qianyang experimental point. Two years of experimental research and promotion show that: the United States amaranth adapts to a wide range of strong resistance, plant tall, rapid growth, high yield, palatability good, high nutritional value, all kinds of livestock are eating. Cultivation in the stubble, 60 to 90 days of growth period, fresh grass yield up to 3400 ~ 7404.4 kg / acre.
