| 摘 要： | 通过对蒙古栎播种苗生长规律及养分状况的分析,结果表明,蒙古栎播种苗高生长加速期有2个高峰期,分别为第20~40天和第60~80天。地径生长量高峰期分别为第20~40天和第100~120天。叶片和茎的氮、磷养分积累表现为生长前期较高而后期较低。钾养分积累表现生长前期较低而后期较高。可依据苗期养分状况进行肥水管理以提高苗木质量。

| Abstract: | The growth & nutrient status of Quercus mongolica seedings were analyzed.Result shows that there are two peaks in growth period of Quercus mongolica seeding, which is from 20 to 40 days and from 60 to 80 days respectively.The growth peak of ground diameter is from 20 to 40 days and from 100 to 120 days respectively.The accumulation of nitrogen & phosphorus in leaves and stems is higher in the early growth stage and lower in later stage.Potassium nutrient accumulation shows lower growth and higher late stage.Fertilizer management can be conducted to improve the quality of seedlings based on nutrient status. |
