| 摘 要： | 该文阐述了土壤含水量对玉米种子发芽及苗期生长的影响试验。结果表明,当土壤含水量在10%以下时,玉米种子发芽势、发芽率和活力指数均显著降低,种子萌发受到抑制;当土壤含水量在15%～20%范围内,玉米种子,发芽势、发芽率和活力指数较高,适宜培育壮苗。5%的土壤含水量为玉米种子萌发和苗期生长的最低预警水分。

| Abstract: | This paper described effect of soilmoisture content on germination and seedling grouth of maize .The results showed that the germination energy, germination rate and vigor index of maize decreased remarkablely under 10% of soil moisture content. Every germination index of maize became higher ,the seedlings come out quickly and aere suitable for cultivating healthy seedingswhen soil moisture content was in range of 15% - 20%.5% of soil moisture content was the mininum early-warning moisture content of germination and seedling stage growth of maize. |
