摘要
选用强筋小麦克05-917、中筋小麦克02-1331、克03-1223、克03-798、克旱20号、新克旱9号和弱筋小麦克丰9号,在正常栽培措施下,研究孕穗期、花期喷施微量元素肥料对其小麦产量的影响。结果表明,各类型春小麦穗粒数、千粒重和产量均有增加,分别平均增加9.1%、3.7%和6.6%。但不同筋型春小麦产量因素变化不同:穗粒数增加量弱筋>中筋>强筋;千粒重增加量强筋>中筋>弱筋,其中中筋品种克03-798千粒重增加量与强筋品种接近。产量增加量弱筋>中筋>强筋。所以微量元素对小麦产量构成因素及产量均有显著的促进作用。
The strong gluten wheat：Ke 05-917,middle gluten wheat：Ke 02-1331,Ke 03-1223,Ke 03-798,Kehan 20,new Kehan 9,low gluten wheat Kefeng 9 were selected as experimental materials in the experiment,the effect of trace element on wheat yield were studied in booting stage and flowering stage under normal cultivation practices,the results showed that the grain number per ear,1000-grain-weight and yield were increased with an average increase of 9.1%,3.7% and 6.6% in different types of wheat,the yield components changes were different in spring wheat with different gluten types,increased amount order of grain number per ear was：low gluten wheat 〉middle gluten〉 strong gluten wheat,increased amount order of 1000-grain-weight was：strong gluten wheat 〉middle gluten wheat 〉low gluten wheat,and the increased amount of 1000-grain-weight of middle gluten wheat Ke 03-798 was close with that of the strong gluten wheat,the increased amount order of yield was：low gluten wheat 〉middle gluten wheat 〉strong gluten wheat,the trace elements could promote wheat yield and yield components significantly.
