摘要
以弱筋小麦品种扬麦9号为试验材料,采用部分重复法进行播期、群体密度、肥料(氮肥、磷肥和钾肥)施用量以及追肥时期对产量和品质的影响效应研究。结果表明:所有试验因子都不同程度地影响弱筋小麦的蛋白质含量;氮肥施用量对产量和蛋白质含量影响最大,随氮肥施用量增加,蛋白质含量显著提高;返青期以后追施氮肥能显著提高蛋白质含量,8.8叶龄期追施氮肥对产量形成影响最大,10.1叶龄期施用,籽粒蛋白质含量最高,但增加磷肥施用量又能显著抑制蛋白质含量的提高;播期对籽粒产量和蛋白质含量起负向作用;群体密度大,钾肥施用水平高,能显著提高弱筋小麦蛋白质含量。
Grain yield and proteirt contents of weak gluten wheat variety Yangmai 9 were studied by partial repeat design for sowing date, population density, fertilizer （ nitrogen, potassium and phosphorus） rate and fertilization topdressing stage. Experimental factors affected the protein contents and grain yield of Yangmai 9 variously. Among those factors, nitrogen rate was the most effective. Protein contents of Yangmai 9 were raised significantly as the nitrogen rates went up. Regreening stage was the best time for protein contents increasing when topdressing nitrogen fertilizer at the same rates. 8. 8- leaf age was the most critical time for yield formation and protein contents reached the highest at 10. 1-leaf age. Sowing date affected grain yield and protein contents negatively. High population density and potassium rates could significantly promoted protein contents of weak gluten wheat Yangmai 9.
