为了研究在高寒地区不同行距、播种量及施肥量对青稞种子产量的影响,试验测定了巴青1号青稞的生育期、株高、考种、种子产量等。结果表明:行距和播种量对青稞生育期影响不大;株高随播种量的增加而减少,随行距的增加而增加;种子产量在行距为15 cm、播种量为220 kg/hm2时达到最大值(242.5 kg/667 m2),故在生产上推荐采用中等播量、中等行距的栽培方式;当施肥量为60 kg/hm2时种子产量最高,达到3 856.5 kg/hm2。
In order to study the effect of different row spacing, seeding rate and fertilizer on the seed yield of barley in alpine region, the growth period, plant height, test variety and seed yield of barley No. 1 were determined. The results showed that row spacing and seeding rate had little effect on the growth of barley. The plant height decreased with the increase of seeding rate and increased with the increase of row spacing. The seed yield reached the maximum at a row spacing of 15 cm and a seeding rate of 220 kg / hm2 (242.5 kg / 667 m2). Therefore, medium-sowing and medium-sowing cultivation is recommended for production. When the fertilizer is 60 kg / hm2, the seed yield is the highest, reaching 3 856.5 kg / hm2.
