施氮量和播种密度对苏啤6号产量、产量构成因素及其蛋白质含量的影响

摘要

以苏啤6号为材料,研究了不同施氮量和播种密度对其产量、产量构成因素及籽粒蛋白质含量的影响.结果表明:施氮量和播种密度对苏啤6号产量、产量构成因素、籽粒蛋白质含量有显著影响.本试验条件下,苏啤6号的适宜施氮量为210 kg/hm2,播种基本苗为300万/hm2.%With the barley variety Supi 6 as material, the effects of nitrogen rate and planting density on yield and yield components and protein content of barley were studied. The results showed that nitrogen appli cation rate and planting density could significantly influent the yield and its components and the protein content in grain of Supi 6. Under the experiment conditions and the optimal nitrogen rate was 210 kg/hm2 and the bas ic seedling number was 3 000 thousand per hectare.
