摘要
为促进玉米高产优质栽培,以德美亚3号为材料,设置3个播期,研究播期对玉米产量和籽粒品质的影响。结果表明:随着播期的推迟,德美亚3号生育期缩短,产量逐渐降低,穗长、穗粗、穗行数、秃尖长、行粒数、鲜重和穗粒数差异显著,百粒重差异不显著,品质中的可溶性蛋白、可溶性糖、油分和粗淀粉含量先升高后降低,粗蛋白含量降低。因此,试验播期范围内,适宜早播有利于粗蛋白含量的积累,提高玉米籽粒品质和产量。
In order to promote high yield and quality cultivation of maize,Demeiya 3 was planted in three sowing dates to determine the effects of different sowing date on yield and quality of maize.The growth period of Demeiya 3 shortened with the delay of sowing data.The results showed that with the delay of sowing date,thegrowth period of Demeiya 3 was shortened and the yield decreased gradually.There were significant differences in ear length,ear diameter,ear row number,bald tip length,grain number per row,fresh weight and grain number per ear,but no significant difference in 100-grain.The content of soluble sugar,soluble protein,oil and crude starch increased gradually first and then decreased,protein content was reduced.In this study,suitable early sowing was favorable for the accumulation of protein content,and it was beneficial to improving seed quality and yield.
