| 摘 要： | 研究了加强甜、超甜玉米品种在砂土、壤土、粘土3种不同质地土壤以及1~3 cm,3~5 cm和5cm以上3种不同播种深度的条件下,不同品种发芽率的变化。结果表明:相同条件下,砂土中甜玉米的发芽率最高,郑甜X61、郑甜2号、郑甜3号的发芽率分别为93.7%,83.3%和86.3%,明显高于壤土和粘土中的发芽率;3种不同播种深度中,3~5cm的发芽率及幼苗整齐度均优于1~3 cm和5 cm以上播种深度。

| Abstract: | The seedling emergence potential of different types of sweet corn hybrids was studied in three types of soil texture and the soil depth of sowing seed.The results show that the seedling emergence ratio of sweet corn hybrids was the highest in loam soil in the same situation and that of ZhengtianX61,Zhengtian 2,Zhengtian 3 were 93.7%,83.3% and 86.3% respectively.In the three depth of sowing seeds,the seedling emergence was the best,when the seedling depth was 3-5cm. |
