中文摘要:
      为了给冀南地区的小麦高产优质栽培提供科学依据,以当地主推小麦品种邯7086为试验材料,研究了不同追氮时期和追氮数量对邯7086产量和品质的影响。结果显示,在一定氮肥总量水平下,分次追施氮肥较一次性追施氮肥可以提高产量,并且可以提高籽粒品质,尤其对籽粒粗蛋白含量的影响较大。研究表明,在中上等地力条件下底施纯N 108 kg·hm-2时,拔节期追施纯N 60~90 kg·hm-2和孕穗期追施纯N 60 kg·hm-2为冀南地区优化的氮肥运筹模式。
英文摘要:
      Han7086, a main wheat cultivar in Hebei, was used in this experiment in order to provide scientific basis for its high yield and quality production in the southern Hebei. The fertilizing was applied at jointing stage and the booting stage, which included four fertilizing levels of 0 kg·hm-2, 60 kg·hm-2, 90 kg·hm-2 and 120 kg·hm-2 at jointing stage, and three fertilizing levels of 0 kg·hm-2, 30 kg·hm-2 and 60 kg·hm-2 at the booting stage, respectively. The result showed that the nitrogen fertilization applied at more times increased the yield and quality than that at one stage, especially for the grain protein concentration. In this experiment, the yield and quality were higher at the nitrogen fertilizer usage of 60~90 kg·hm-2 at jointing stage, 60 kg·hm-2 at booting stage and 108 kg·hm-2 before seeding.
