在中等肥力条件下试验结果表明 :在总施氮量相同的条件下 ,增加底肥的比例对促进小麦幼苗生长有利。增加追肥的比例对中后期小麦营养生长、生殖生长和成产因素有促进作用 ,最终表现为增产。增加追肥比例可以显著提高籽粒蛋白质含量 ,改善小麦品质 Under medium fertility condition, the results showed that under the same total nitrogen application, increasing the proportion of base fertilizer was beneficial to the growth of wheat seedlings. Increase the proportion of topdressing wheat nutrition growth, reproductive growth and production factors have a catalytic role, the final performance for the increase. Increasing the proportion of top dressing can significantly increase grain protein content and improve wheat quality
