本实验采用两种播期,对两个优良甜玉米杂交种,进行3种施肥方式的田间试验。结果表明:适当延迟播种期,有利于改善甜玉米的生理功能和产量的提高;两个优良品种当中吉甜5号的表现优于吉甜3号;第二种施肥方式对甜玉米各主要数量性状的影响较好。因此,适当延迟播种期,采用吉甜5号,按第二种施肥方式进行施肥,是改善甜玉米品质增加产量的最优处理组合。
In this experiment, two kinds of sowing dates were used to test two good sweet corn hybrids in three field experiments. The results showed that proper sowing time could improve the physiological function and yield of sweet corn. Jitian 5 was better than Jitian 3 in the two fine varieties. The second fertilization method could improve the quality of sweet corn. The effect is better. Therefore, the appropriate delay in sowing, using Ji Tian 5, according to the second fertilization mode of fertilization, is to improve the quality of sweet corn yield the best combination of processing.
