    摘要:

    藜麦因其丰富的遗传多样性和广泛的适应性而被世界各地引进种植,为探讨藜麦秋季种植及将其作为观赏植物开发 利用的可行性,试验选取了 Q1~Q13 共 13 个材料进行秋播,通过对各材料生育进程、性状表现和单株产量的观察测定,研究 秋播藜麦的生长发育规律和观赏特性。 结果表明:秋播藜麦生育期较长,或不能成熟,各生育阶段中,灌浆至成熟所需时间最 长ꎻ秋播藜麦植株较矮,茎细、分枝少,穗较短,单株产量较低,不同材料之间差异较大ꎻ藜麦观赏性则主要体现在株型、穗型和 叶片、茎秆、穗的颜色上,多数材料在显穗至成熟期观赏特征明显,不同材料叶色、茎色、穗色差异较大。 试验初步筛选出 Q2、 Q4 和 Q6 具有较好的综合性状,可进一步扩大田间试验,为丰富藜麦种植模式及发展生态旅游观光农业提供一些参考。

    Abstract:

    Quinoa has been introduced to the whole world for its rich genetic diversity and strong adaptability. To explore the feasibility of growing quinoa in autumn and to develop it as an ornamental plantꎬ 13 materials were selected for autumn sowing in this experiment. The growth and development patterns and ornamental characteristics of autumn-sown quinoa were studied through the fertility processꎬ trait performance and single plant yield of each material. The results showed that autumn-sown quinoa had a long or immature fertility period. Among the fertility stagesꎬ quinoa took the longest time from filling to maturity. Autumn-sown quinoa plants were characterized with shorter heightsꎬ thin stemsꎬ fewer branchesꎬ shor ̄ ter spikesꎬ and lower yield per plantꎬ with distinctions among different materials. The ornamental properties of quinoa are mainly embodied in the shapes of the plants and spikes and the colors of leavesꎬ stalks and spikes. Most of the materials showed distinct ornamental characteristics during the period from the spike budding to maturity. Leafꎬ stem and spike col ̄ ors varied greatly among the materials. The trial selected Q2ꎬ Q4 and Q6 with better performanceꎬ which can be further experimented in field trials. This study provides some references for enriching quinoa planting patterns and developing eco -tourism and touristic agriculture.
