西藏隆子黑青稞“3414”肥料效应试验

Experiment on ‘3414’ Fertilizer Effect of Black Barley in Longzi,Tibet

青稞是西藏的重要粮食作物,2017年西藏自治区政府做出了提高青稞单产的重要指示,而在提升青稞产量过程中,肥料发挥了有效作用。通过在隆子县进行青稞3414试验,发现氮肥对青稞的增产有显著作用,经分析该地区合理施肥量为纯氮12.4kg/667m^2、纯磷3.054 kg/667m^2,纯钾1.61 kg/667m^2时,青稞最大产量为240.4～278 kg/667m^2。推荐施肥结果能为青稞栽培提供合理方案和土壤培肥提供科学依据。

Highland barley is an important food crop in Tibet. In 2017,the Tibet Autonomous Region government made an important direction to increase barley yield,and fertilizers have played an effective role in raising barley production. Through the trial of‘3414’in Longzi county,it was found that nitrogen fertilizer had a significant effect on the yield increase of barley. After analysis,the reasonable fertilizing amount in the area was pure nitrogen 12. 4 kg/mu,pure phosphorus 3. 054 kg/mu and pure potassium 1. 61 kg/mu. The maximum output is 240. 4-278 kg/mu. It is suggested that the results of fertilization can provide scientific basis for the reasonable plan for cultivation of barley and soil fertilization.
