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.
