| 摘要: |
| 84年我们对河北千穗谷、云南苋、芬兰苋等拉用苋品种的主要生物学特性和营养品质进行了研究和分析。结果表明:(1)苋籽含有16%左右的蛋白质,又有平衡的氮基酸组成,尤其赖氨酸含量高达1%左右。还含有约6%的脂肪。在收获籽粒后的茎、叶、穗中,其蛋白质和赖氨酸含量均远远高于玉米籽粒,是一种营养价值高的食、饲兼用的作物。(2)粒用苋生长速度快,生长势强。在80多天的整个生长期中,亩产鲜重万斤以上,干物重1500—2000斤/亩,籽粒产量300—600斤/亩,是一种干物质生产量大、光合效率高的作物。(8)粒用苋在28—40℃范围内,不仅发芽势强,而且发芽率也高,具有明显的适合高温发芽的特性。苋籽在0.4%以下的 NaCl 溶液中能正常发芽,具有较强的耐盐性。在土壤瘠薄和水分不足的条件下,粒用苋仍能正常生长,具有明显的耐瘠,耐旱性。因此,粒用苋是一种适应性广,抗逆性强的作物。 |

| Abstract: |
| The biological characteristics of three amaranth varieties,Hebei Qian-Sui-Gu(local variety),Yunnan amaranth and Finland amaranth were studied in 1984.And the nutritive qualities in all parts of the plant at harvest time were also analysed respectively.The main results show that: 1)the amaranth grain contains about 16% protein and 6% of fat,the amino acid composition of protein being balanced.The content of lysine is as high as 1%.At harvest time,the content of protein and lysine in stems,leaves and heads is... |
