不同品种玉米施用液体配方肥产量差异分析

为深入探究不同品种玉米产量的差异,本试验以MC670、农华101、农华5号和农华106为试验材料,对其产量及产量构成因素进行分析。结果表明:农华5号表现最好,亩穗数最多出苗率最高,分别为5188个和98.5 %,较其他均增加1.3 % ~ 2.67 %；籽粒含水量最低,为24.33 %,较其他减少1.14 % ~ 3.07 %；穗籽粒干重为199 g,较其他增加3.1 % ~ 12.6 %；穗粒数为563粒,较农华101增加9.7 %；百粒重为35.3 g,较其他增加2.4 % ~ 17.4 %；亩产量最高,为1031.5 kg,较其他增加5.8 % ~ 14.6 %。因此,农华5号可作为高产品种在当地推广种植。

In order to explore the yield difference of different varieties of maize, MC670, Nonghua 101, Nonghua 5 and Nonghua 106 were used as experimental materials to analyze their yield and yield components. The results showed that Nonghua 5 had the best performance, and the highest seedling emergence rate was 5188 ears per mu and 98. 9 ears per mu. 5 the grain water content was the lowest (24.33%) and decreased (1.14% ~ 3.07%). The dry weight of panicle grain was 199 g, the number of grains per ear was 563, which was 9.7% higher than that of Nonghua 101. The 100-grain weight was 35.3 g, increased by 2.4% ~ 17.4%, and the yield per mu was 1031.5 kg, increased by 5.8% ~ 14.6%. Therefore, Nonghua 5 can be used as a high yield variety in the local area.
