籽粒苋是一种适应性广的粮、菜、饲料兼用作物。种植籽粒苋对于增加粮食总产、发展畜牧业均有重要意义。为鉴别我省当前示范推广的几个主要品种的经济性状,发挥良种的作用,于1990年在海拔1877米的姚安县农职中学试验地进行了品种比较试验。参试品种有姚安白苋和云南省农科院园艺所提供的美国二号、K_(112)、R_(104)、昆明红苋及蒙自苋。试验用地为褐色土壤,前作小麦,小区面积12米~2,重复三次,随机区组排列,分别考察刈割与否情况下各品种的经济性状,数据处理用新复极差法。
Grain amaranth is a wide adaptability of food, vegetables, feed and crops. Planting grain amaranth is of great significance for increasing total grain output and developing livestock husbandry. In order to identify the economic performance of several major varieties of the demonstration and promotion in our province and to play a role of good seed, a variety comparison experiment was carried out in 1990 in Yao’an County High Vocational School of Agriculture at an altitude of 1877 meters. The varieties tested include Yao’an amaranth and Yunnan Academy of Agricultural Sciences horticultural provided by the United States on the 2nd, K_ (112), R_ (104), Kunming amaranth and Mongolia from amaranth. The test site was brown soil. Before the operation, the area of wheat was 12m ~ 2. The plots were repeated three times and randomly arranged in groups. The economic traits of the cultivars under the condition of cutting or not were respectively examined.
