Two wheat cultivars, strong-gluten Yumai66 and medium-strong-gluten Yumai49, were usedto test the effects of irrigation and nitrogen application regimes on cooking quality ofChinese noodle in 2001-2002. The results showed that both in Yumai49 and Yumai66, valueof total organic matter (TOM) of noodle and noodle cooking loss rate ranked the firstwhile noodle score (NS) ranked the lowest in treatments without any nitrogen application.As nitrogen application rate increased, TOM value decreased but NS increased. The lowestTOM and the highest NS existed for treatments with 225 and 150 kg N ha-1 in Yumai49 andYumai66, respectively. Increasing irrigation resulted in greater TOM and NS, but lessbroken noodles. However, no significant difference was found in NS among differentirrigation treatments. Significant difference was found in TOM, NS, breaking rate andwater absorption rate of noodle between these two cultivars. Yumai49, with an average TOMvalue of 1.19 g and NS of 88.5, was better than Yumai66, with an average TOM value of1.55 and NS of 85.7. Interaction in TOM value was found between irrigation and nitrogenapplication. Effects of nitrogen fertilization were greater than that of irrigation inYumai49, while in Yumai66 the other way round. It is suggested, therefore, thosedifferent irrigation and nitrogen application regimes be chosen in production practicebased upon cultivar quality traits. 展开更多

With increasing water shortage resources and extravagant nitrogen application, there is an urgent need to optimize irrigation regimes and nitrogen management for winter wheat(Triticum aestivum L.) in the North China Plain(NCP). A 4-year field experiment was conducted to evaluate the effect of three irrigation levels(W1, irrigation once at jointing stage; W2, irrigation once at jointing and once at heading stage; W3, irrigation once at jointing, once at heading, and once at filling stage; 60 mm each irrigation) and four N fertilizer rates(N0, 0; N1, 100 kg N ha-(-1); N2, 200 kg N ha-(-1); N3, 300 kg N ha-(-1)) on wheat yield, water use efficiency, fertilizer agronomic efficiency, and economic benefits. The results showed that wheat yield under W2 condition was similar to that under W3, and greater than that under W1 at the same nitrogen level. Yield with the N1 treatment was higher than that with the N0 treatment, but not significantly different from that obtained with the N2 and N3 treatments. The W2 N1 treatment resulted in the highest water use and fertilizer agronomic efficiencies. Compared with local traditional practice(W3 N3), the net income and output-input ratio of W2 N1 were greater by 12.3 and 19.5%, respectively. These findings suggest that two irrigation events of 60 mm each coupled with application of 100 kg N ha-(–1) is sufficient to provide a high wheat yield during drought growing seasons in the NCP. 展开更多
