| 为研究冬小麦不同品种植株性状和氮效率的差异袁于2008要2009年在河北农业大学标本园对中国春-Synthetic 6xA 组7 个染色体代换系及其亲本进行研究袁采用裂区设计袁设置正常施氮渊CK冤和低氮渊N-冤两个处理袁在不同施氮条件下对7 个染色体代换系及中国春植株单株干重尧全氮含量尧氮累积量进行分析袁结果表明袁施氮水平对小麦产量和单株氮累积量的影响是直接而显著的袁其中4A 在正常供氮或者高氮条件下才会有较高的氮素利用率袁对低氮环境很敏感遥 |
| 英文摘要: |
| In order to study the differences of plant growth traits and nitrogen production efficiency in different winter wheat varieties, the experiment about Chinese Spring-Substitution lines in wheat and the materials was carried out at the experimental station of Hebei Agricultural University in 2008要2009. The experiment containing nitrogen supplication and non supply nitrogen supplication in spring was conducted by split-plot design. Under different N-condition, the study analyzed the plant growth traits including the dry mass per plant, the accumulative N amount per plant and nitrogen content. The resutts showed that the effect of N level was directly and significant on yield performance as well as the accumulative N amount per plant. 4A could be the high N-efficiency variety under nitrogen supplication or high nitrogen level and was more sensitive to the low-N condition. |
