美国籽粒苋是苋科苋属一年生优质高产新型饲料、粮食、蔬菜兼用草本植物。本试验采用随机区组排列,重复3次,初步观察和测定了N01、N02、N03、K112和R 104共5个优良品种的9个主要的饲用性状,探讨其饲用潜力。结果表明:饲用性状优良,具有光合作用强、生长迅速、产量和营养价值高、适应性广、抗逆性强、繁殖系数极高的特点。可作为荒地先锋作物,在不挤占耕地的前提下,开发利用低产地、弃耕地、盐碱地、沿海滩涂以及荒坡荒沟,建立巩固的饲料基地,解决目前饲料蛋白质不足,促进畜牧业发展有一定潜力。
American amaranth is amaranth Amarantha annual high-quality new feed, food, vegetables and herbs. In this experiment, randomized block array was used and repeated three times. The main feeding characters of five excellent varieties N01, N02, N03, K112 and R 104 were primarily observed and determined, and their potential for feeding was discussed. The results showed that the forage had the characteristics of good photosynthesis, rapid growth, high yield and nutritional value, wide adaptability, strong resistance and high propagation coefficient. It can be used as a pioneer crop of wasteland, and under the precondition of not occupying arable land, develop and utilize a low-producing area, abandoned farmland, saline-alkali land, coastal tidal flats and barren ditch wasteland to establish a consolidated feed base to solve the current lack of feed protein and promote livestock husbandry development. potential.
