| 摘 要： | 在温室大棚条件下对不同苜蓿(Medicago L.)品种的再生速度、产草量与环境因子进行了灰色关联度分析。结果表明:影响苜蓿再生速度和产草量的主要环境因子是温度,室温与所有苜蓿品种产草量的关联度都是第1位的。刈割留茬高度为5cm时苜蓿品种的再生速度与室温的关联度较高;留茬8cm和10cm时与环境因子的关联度没有明显的规律。

| Abstract: | The correlation degree of plant yield and regeneration speed with environmental factors in different Alfalfa cultivars under greenhouse condition were studied by Grey correlation degree analysis.Results indicated that temperature was the main environmental factor affecting regeneration speed and plant yield of Alfalfa.The correlation degree between room temperature and yield was the highest for all tested cultivars compared to other factors.The correlation degree between the regeneration speed of Alfalfa and room temperature was higher than other tested correlation when the stubble height was 5 cm.However,there was no obvious correlation between the two factors when the stubble height was 8 cm and 10 cm. |
