摘要
以陇藜1号藜麦品种为试验材料,研究了不同种植密度对藜麦生育期、生长及产量的影响.结果表明:合理的种植密度可帮助藜麦植株充分利用水、光照、肥料等资源,达到增产增收的目的.随着种植密度的减小,藜麦生育期呈现缩短趋势,株高、倒折率呈减小趋势,千粒质量、单株产量呈增长趋势,单位面积产量呈现出先升高、后降低的趋势,得出甘肃省平川区藜麦适宜的种植密度为69 000～85 500株/hm2.
Abstract
The effects of different planting densities on the growth period,growth and yield of Chenopodium quinoa Longli No.1 were studied.The results showed that reasonable planting density could helpChenopodium quinoaplants make full use of water,light,fertilizer and other resources to increase yield and income.With the decrease of planting density,the growth period ofChenopodium quinoadecreased,plant height and inversion rate decreased,thousand grain weight and yield per plant increased,and the yield per unit area increased first and then decreased.It was concluded that the appropriate planting density ofChenopodium quinoain Pingch-uan District of Gansu Province was 69 000～85 500 plants/hm2.
