摘要:
为了提高寒地半干旱地区糜子产量及品质，采用随机区组设计，设5个施氮水平（0、45、60、135、180 kg?hm-2），研究了不同施氮量对糜子产量和品质的影响。结果表明：随着施氮量水平的增加，糜子产量先升后降呈单峰曲线变化，有极大值，过量施用氮肥会导致糜子产量下降；糜子粗蛋白含量和脂肪含量随着施氮量的增加而逐渐提高，淀粉含量、直链淀粉含量、支链淀粉含量均随着施氮量的增加而下降，呈负相关。当氮肥水平为45~60 kg?hm-2时，糜子的产量最高、品质较好。
Abstract:
In order to improve the yield and quality of broomcorn millet in semi-arid region,the impact of different nitrogen levels on the yield and quality of broomcorn millet was studied using a randomized block design and five levels for nitrogen(0,45,60,135,180 kg?hm-2）.The results showed that,with increasing of nitrogen level,the yield of broomcorn millet increased firstly and then decreased,the excessive nitrogen could decrease broomcorn millet yield.Crude protein content and fat content increased with the increasing of nitrogen level,starch content,amylose contnt,amylopectin decreased with the increasing of nitrogen level,when nitrogen level was 45~60 kg?hm-2,the yield of broomcorn millet was the highest and the quality was the best.
