摘要: 为了确定冀东地区冬小麦的最佳追氮时期和追氮量,实现氮肥资源高效利用。采用田间试验方法,研究了总氮肥量240 kg/hm2条件下,分期施用氮肥对冬小麦干物质积累和产量的影响。试验采用京冬8号和京冬11号2个冬小麦品种。设4个处理:全部底肥(NⅠ);1/2底肥、1/2起身(NⅡ);1/2底肥、1/2拔节(NⅢ);1/3底肥、1/3起身、1/3挑旗(NⅣ)。NⅢ处理有利于小麦建立合理的群体结构,穗粒数和千粒重分别比其他处理平均提高4.41%~13.00%和3.04%~14.97%,从而提高了小麦产量。在小麦施氮总量一定的情况下,氮肥分期施用,即氮总量的1/2作底肥,1/2做拔节期追肥有利于小麦产量的提高。

关键词: 冬小麦, 氮肥, 分期施用, 产量

Abstract: The objectives of this study were to determine the best nitrogen topdressing stage and nitrogen rate for profitable yield and high efficient nitrogen utilization in winter wheat in eastern of Hebei province.Field experiments were conducted to investigate the effects of nitrogen fertilizer timing on the dry matter accumulation and grain yield of winter wheat with the total pure N 240 kg/ha.The urea was used with different fractions being applied at planting,reviving,stem elongation and flag leaf.Four nitrogen treatments were applied among planting,reviving,stem elongation,and flag leaf:240-0-0-0(NⅠ),120-120-0-0(NⅡ),120-0-120-0(NⅢ) and 80-80-0-80(NⅣ) kg/ha.The results showed that the nitrogen fertilizer applied at planting and stem elongation not only established a reasonable of the group structure but also improved kernels per spike from 4.41% to 13.00% and thousand kernel weight from 3.04% to 14.97%.Thus the wheat yield was improved.The research has a conclusion that,on wheat nitrogen of a certain circumstance,half of the all nitrogen fertilizer using in sowing and half of the nitrogen fertilizer using in stem elongation is in favour of increasing the yield of wheat.
