【摘要】 研究了氮肥不同底追比例对强筋小麦品种济南17籽粒品质和产量的影响。结果表明,适当增大拔节期追施氮肥的比例能够显著提高亩穗数、穗粒数和千粒重而提高小麦籽粒产量,增大拔节期追施氮肥的比例也能够提高小麦籽粒的品质性状,综合产量和品质认为以总氮量的1/2作基肥1/2作追肥或总氮量的1/3作基肥2/3作追肥为宜。更多还原

【Abstract】 The effects of different proportion of basal nitrogen and topdressing nitrogen on grain quality and yield of strong gluten wheat variety jinan 17 are studied in the article. The results show, properly augmenting the topdressing nitrogen proportion on jointing stage can remarkably increase the number of the spikes per 667m2?the number of the kernels per spike and the weight of thousand kernels to enhance the wheat yield and can improve the qualitative character, integrating the yield and the quality, we think it is proper to make 1/2 of the total nitrogen as basal fertilizer and 1/2 as topdressing fertilizer or 1/3 as basal fertilizer and 2/3 as topdressing fertilizer.更多还原
