| 摘 要： | 测定了不同播种深度对4种牧草种子萌发时营养物质消耗量的影响。结果表明:播种深度与种子萌发过程中营养物质消耗量具有显著正相关关系(P<0.01);不同牧草种子所适应的播种深度不同,莞根与无芒雀麦以1.5cm左右为宜,中华羊茅适于0.5～1.5cm,燕麦播深以3～4cm为佳。

| Abstract: | The effect of sowing depth on nutritional consumption of4germinating herbage seeds was determined.The re-sult showed that the sowing depth had a significant positive correlation(p<0.01)with the amount of nutritional consump-tion of germinating seeds.Different seeds suited different sowing depth.Bressica rapa L.,Bromus inermis Leyss,Festuca sinensis Keng and Avena sativa L.should take the sowing depth of1.5cm,0.5～1.5cm,3～4cm respectively as the best. |

| Keywords: | Herbage seed Sowing depth Amount of the nutritional consumption |
