| 摘 要： | 对二龄苜蓿群落地上部分与根系氮素及总糖含量季节动态进行了测定。结果表明:苜蓿地上部含N量随物候期的推移呈下降趋势,根部含N量动态均呈双峰型,第一个峰值在春季,第二个峰值在秋初;苜蓿地上部分和根系总糖含量均呈双峰型,最大值均出现在生长末期;4种苜蓿相比,农菁1号苜蓿地上部分与根系氮素及总糖含量均最大。 |

| Abstract: | The nitrogen and total sugar content in herbages on four Medicago varia was studied.The results showed that the aboveground nitrogen content of Medicago varia was dearease by degrees along with phenophase's process.The nitrogen content in the roots of Medicago varia was both higher in early growing period,then they dropped down they came into their reproductive growth stage,rised up after mature period;Dynamics of total sugar content in the aboveground and roots of Medicago varia were double apex pattern.The maximum was appeared at end of growth;Compared with four Medicago varia,the nitrogen and total sugar content in root and aboveground of NongJing No.1 alfalfa were the biggest. |
| Keywords: | Medicago varia nitrogen total sugar |
