新疆伊犁河谷藜麦适应性研究初报

Preliminary Study on Adaptability of Quinoa in Ili Valley of Xinjiang

为研究藜麦在伊犁河谷的适应性,利用引进的藜麦材料,设置不同种植密度条件下的适应性试验,对其进行农艺性状和产量对比。结果表明,藜麦在伊犁河谷生育期为125 d左右,在不同种植密度条件下,株高、茎粗、有效分枝数等均存在差异,理论产量差异达极显著,LM2(株距15 cm)较LM5(株距30 cm)处理产量增加31.96%。研究初步认为,伊犁河谷地区藜麦种植密度为0.67万~1.33万株/hm^2时容易获得高产。

To study the adaptability of quinoa in Ili valley,the paper used the imported quinoa materials,set the adaptability test of different planting density condition,compared the agronomic traits,leaf area index,dry matter accumulation and yield.The results showed that the growth period of quinoa in Ili valley was 125 days.There were differences in plant height,stem diameter and effective branch number,etc.,under different densities conditions,theoretical yield had very significant difference,LM2(spacing 15 cm)production increased by 31.96%compared with LM5(spacing 30 cm).This paper suggests that the planting density of quinoa in Ili Valley is easy to obtain high yield when the plant density is 6 700-13 300 plants/hm2.
