| 摘要：我国新疆地区水资源非常匮缺，传统的灌溉模式导致水肥流失严重以及环境污染，不利于土地的可持续利用，而滴灌技术很好的解决了这个问题。常规的滴灌模式有“一管4，5，6行”（滴灌带毛管间距60，75，90 cm）三种，其中 “一管6行” 相较于“一管4行”，植株生长不均匀、产量较低，但其滴水周期短，各行土壤湿润深度较一致且经济效益高。在该地区筛选适宜采用“一管6行”滴管模式的小麦品种能在文持产量和品质的水平上更好的节约用水量，从而提高经济效益。因此，本试验在“一管6行”的滴灌配置下对10个新疆地区的春小麦品种的产量和品质进行分析，结果表明，新春40和新春44产量较高且行间差异较小，其叶面积和伤流液值较大，并且均与产量呈显著相关性；而新春11和新春22产量较低且行间差异较大，其叶面积和伤流液的值较小，并且均与产量无明显相关性。新春22、新春35、新春44蛋白含量较高，但新春22和新春35行间差异大；新春37和新春40的干湿面筋含量较高，但新春37的干湿面筋行间差异较大。总之，在“一管6行”滴灌模式下，新春40和新春44其产量行间变异小，且产量和品质较高，更符合新疆滴灌小麦品种稳产优质的筛选条件。26613 毕业论文关键词：滴灌；不同基因型；春小麦；产量；品质 Effect of drip irrigation on yield and quality of spring wheat with different genotypes in Xinjiang Abstract: There has a very limit water resources in the northwest China of Xinjiang. Under the traditional irrigation mode, the loss of water and fertilizer is serious, which not only wastes resources, but also causes serious pollution to the environment. This is not conducive to the sustainable use of land, but drip irrigation technology is a good solution to this problem. Conventional drip irrigation mode has "one tube for 4, 5, 6 rows" (drip irrigation with capillary spacing of 60, 75, 90 cm), One tube for 6 rows compared to one tube for 4 rows, the plant growth is not uniform, the yield is low, but its water cycle is short, the soil moisture depth is consistent and the economic benefits are high. In this area, the suitable " one tube for six rows " dropper model can save water in maintaining the yield and quality, so as to improve the economic benefit. In this experiment, the yield and quality of Spring Wheat Varieties in 10 areas of Xinjiang were analyzed under one tube for six rows. The results showed that the difference of yield between rows were smaller, and the yield was higher in spring wheat 40 and 44. Meanwhile, the leaf area and xylem sap were larger, which have a significant relationship with the yield. The difference of yield between rows were larger and the yield was lower in spring wheat 11 and 22. The leaf area and xylem sap were smaller, but there were no significant relationship with the yield. The content of protein is higher in spring wheat 22、35 and 44, but the difference of content between rows were larger in spring wheat 22 and 35. The wet and dry gluten content was higher in spring wheat 37 and 40, but there was a great difference between the wet and dry gluten in spring wheat 37. In a word, under the drip irrigation model of " one tube for six rows ", the variation of the yield between the spring wheat 40 and 44 is small, and the yield and quality are higher, which are more suitable for the screening of the stable and high quality wheat varieties under drip irrigation in Xinjiang.
