为探讨小麦新品种周麦27号的高产优质配套栽培技术,采用4因子2次正交旋转组合设计,研究了播期、播量、追施氮肥期和喷施多效唑对周麦27号主要农艺性状和品质特性的影响。结果表明,周麦27号属矮秆大穗品种,产量主要受播期影响,回归方程为Y=10347.3-516.3X1,预测产量最大值可达到11 215.5kg/hm2,并且产量三要素较协调,适合高产要求。子粒蛋白质含量等多数与蛋白质数量相关的指标均与播期呈显著负向线性关系,面筋指数等与蛋白质质量相关的指标受栽培措施影响较大。建议周麦27号在高肥水地块于10月13号左右播种,基本苗在234万/hm2左右,于3月中上旬追施尿素225kg/hm2,喷施多效唑1 195.5g/hm2,若预测播期温度较高,播种期可适当推迟,增加播量。
In order to explore the high-yield and good-quality cultivation techniques for a new wheat variety Zhoumai 27, orthogonal design of 4 factors and 2 orthogonal rotations was used to study the effects of sowing date, sowing date, topdressing nitrogen fertilizer period and spraying paclobutrazol on the main agronomic characters of Zhoumai 27 Effects of traits and quality characteristics. The results showed that Zhoumai 27 was a dwarf big-spike cultivar whose yield was mainly affected by sowing date. The regression equation was Y = 10347.3-516.3X1, the predicted yield could reach 11 215.5kg / hm2, and the three factors of yield were more coordinated. Suitable for high yield requirements. Grain protein content and most of the indicators related to the number of proteins were significantly negatively correlated with the sowing date, gluten index and other indicators of protein quality are greatly affected by the cultivation measures. It is suggested that Zhoumai 27 should sow in high-fertility land at around October 13 with basic seedlings at about 234 million / hm2. In the middle of March, urea 225kg / hm2 should be topdressed and paclobutrazol 1 195.5g / hm2 should be sprayed. Sowing temperature is higher, the sowing period may be postponed, increase the sowing.
