| 中文摘要: |
| 在控制自然降雨条件下,分析灌水时期与次数对强筋小麦产量和品质的影响,结果表明:越冬水可促进小麦群体形成,但后期缺水,产量不高;拔节水能提高成穗率,增加穗粒数;灌浆水处理单位面积穗数、穗粒数都低,产量偏低。拔节水处理产量与水分利用效率最高,分别比越冬水处理和灌浆水处理提高了13.78%、72.26%和10.29%、47.06%。随着灌水次数增加,产量水平有所提高,但水分利用效率则降低。小麦生育后期灌水和灌水次数的增加对强筋麦的品质不利,特别是灌浆水大大降低了强筋麦的品质。综合产量、水分利用效率,品质三方面因素,优质强筋麦生产上要浇好越冬水和拔节水。 |
| 英文摘要: |
| The yield and quality of high-gluten wheat under the condition of controlling irrigation in different phase and with different times were studied.The results showed that the winter water can improve formation of wheat colony,but water is deficient in late period,yield will be low;irrigation in jointing phase can improve forming spike and increasing grains;with irrigation in grouting phase the yield will be low.In term of different irrigation stages,irrigation in jointing has the highest yield and the highest water use efficiency(WUE) Compared to irrigations in winter and grouting,the yield increases by 13.78% and 72.26%,respectively,and WUE increases by 10.29% and 47.06%,respectively.As the irrigation times increases,the yield will be higher,but the WUE will be lower.Watering in Grouting reduces the quality of high-gluten wheat.In view of yield,WUE and quality,irrigations in winter and in jointing are the best way for high-gluten wheat production. |
