为找出鲁西地区强筋小麦的最佳耕作方式与施氮量,为强筋小麦优质高产栽培理论提供依据,以强筋小麦品种洲元9369为材料,在免耕、深耕、旋耕三种耕作方式下研究了四种施氮量(165、225、300、360kg/hm2)对强筋小麦的影响。结果表明:在三种耕作方式下,各时期小麦群体都随着施氮量的增加而增加,但施氮量达到一定水平后群体增加缓慢,相同施氮量时深耕处理的小麦群体最大;施氮虽然增加群体,但并没有增加叶面积指数,越冬期以后叶面积指数与施氮量成反比,相同施氮量时深耕处理的小麦籽粒蛋白质含量最高;在三种耕作方式下,蛋白质含量、湿面筋含量、沉淀值、形成时间和稳定时间等品质指标均随施氮量的增加而增加;深耕且300 kg/hm2施氮量处理的强筋小麦产量最高。
In order to find out the best tillage mode and nitrogen application rate of strong gluten wheat in Luxi area, this study provided the basis for the high yield and high yielding cultivation of strong gluten wheat. Using the strong gluten wheat variety Zhouyuan 9369 as material, The effects of four nitrogen rates (165, 225, 300, 360 kg / hm2) on strong gluten wheat were studied under tillage. The results showed that under the three tillage modes, the population of wheat increased with the increase of N application rate at each period, but the population increased slowly when the N application rate reached a certain level. Although nitrogen increased the population, it did not increase the leaf area index. After the winter, the leaf area index was inversely proportional to the amount of nitrogen application. The grain protein content of wheat under deep-tillage treatment under the same nitrogen application rate was the highest. Under the three tillage modes, the protein content, The wet gluten content, sedimentation value, formation time and stability time all increased with the increase of nitrogen application rate. The yield of strong gluten wheat under deep plowing and nitrogen application of 300 kg / hm2 was the highest.
