摘 要:以徐麦29为试验材料,研究了氮肥运筹对中筋小麦品种产量和品质的影响,以期为高产优质高效栽培措施的选择提供依据。结果表明:在磷、钾保持适当用量,施氮量按基追比7:3的条件下,随着施氮量的增加可显著提高籽粒产量、湿面筋含量、干面筋含量和粗蛋白含量。在施氮量为300 kg/hm2时徐麦29产量达到了8403 kg/hm2,比不施氮肥时的产量6660 kg/hm2增长了1743 kg/hm2;湿面筋含量、干面筋含量、面筋指数、粗蛋白含量均得到改善,但形成时间、稳定时间、吸水率、评价值有所降低。Two barley varieties, Supi3 and Dan2 were planted to study the response of yield, 1000 - kernel weights and grain protein content to nitrogen application in malting barley. Four results were concluded : ( 1 ) Gain protein content increased with raised nitrogen levels and application of nitrogen at the later stage of the same nitrogen level. (2) 6833. 68 kg/hm2 and 7055. 91 kg/hm2 grain yield of two varieties was highest at N rate of 225 kg ha -1 and ratio of base to topdressing 7: 3. (3) 1000 -kernel weights was effected greatly by nitrogen applied quantity, diversity of 1000 -kernel weights in different barley varieties was mainly determined by genetic diversity of varieties, and secondary by nitrogen strategy. (4) Supi3 was greatly superior to Dan2 in general comment, so in order to obtain high yield and benefit, Dan2 should be substituted by Supi3 in large area production to improve yield and quality of malting barley.
