摘要
为了给不同类型专用小麦大面积生产提供科学的施肥依据,利用不同氮素水平进行处理,分析了氮素施用量对强筋、中筋和弱筋三种类型品种品质性状的影响。结果表明,施氮量在0～300kg/hm2范围内,氮素与强筋和中筋品种的蛋白质含量呈显著正相关,与弱筋品种呈二次曲线关系;增施氮素能显著提高沉降值,降低弱化度,延长面团的形成时间和稳定时间,对增加面筋含量也具有一定的作用;粉质评价值随施氮量的增加而逐渐提高,公顷施氮量达到225kg后,氮素的调节效应减弱,中强筋品种出现负效应。
The effects of different nitrogen applied amounts on quality characters of different types of wheat (varieties) (strong, middle and weak gluten type) were studied. The result showed that the (correlation) (between) the application rate of N-fertilizer and protein content of strong (or middle) gluten (variety) was (significantly) (positive) whereas it was in a relation of quadric curve with protein content of weak gluten (variety). With the (increase) of nitrogen applied, the sedimentation value was significantly (increased), the degree of softening was (reduced), the development time and (stability) time was prolonged, and the wet gluten content could (also) be (increased). With the (increase) of nitrogen fertilizer applied, the development time and (stability) from farinograph gradually rose. When the amount of N application was more than 225 kg/hm^2, the regulation (effect) of nitrogen was weakened, and showed a negative effect of nitrogen on strong (or middle) gluten variety.
