摘要
以河北省秦皇岛市青龙满族自治县为试验区域,以强硕68玉米品种为供试材料,系统探讨了常规旋耕(CK)、深松35 cm+免耕(T_(1))、深松35 cm+旋耕25 cm(T_(2))、灭茬耙(T_(3))及免耕(T_(4))5种耕作方式对玉米籽粒品质及产量的影响。结果表明,深松处理(T_(1)和T_(2))显著提高了玉米产量和籽粒蛋白质含量;免耕因播种密度不足导致产量最低,产量排序为T_(1)>T_(2)>T_(3)>CK>T_(4),其中T1处理产量达5384.52 kg/hm^(2),较CK增产13.59%;籽粒品质方面,T1处理蛋白质含量最高(15.49%),CK处理的淀粉含量(34.20%)显著优于其他处理。研究结论为青龙满族自治县玉米高产优质栽培提供了理论依据。
Took Qinglong Manchu Autonomous County as the experimental area and Qiangshuo 68 maize variety as the test material,the effects of five tillage methods on the quality and yield of maize kernels were systematically explored.The results showed that deep loosening treatment significantly increased maize yield and grain protein content,while no-till treatment had the lowest yield due to insufficient sowing density.In terms of grain quality,the protein content of T1 treatment was the highest,and the starch content of CK treatment was significantly better than that of other treatments.The research conclusion provided a theoretical basis for the high yield and high quality cultivation of maize in Qinglong Manchu Autonomous County.
