紫花苜蓿粗蛋白质含量影响因素的研究

分析了紫花苜蓿品种的遗传特性、生育期、施肥、田间管理、地老虎虫害等因素对紫花苜蓿粗蛋白质含量的影响。结果表明:紫花苜蓿粗蛋白质含量在不同品种上存在差异。从营养生长期到结荚期,粗蛋白质CP含量呈逐步下降的超势;施肥能够显著增加苜蓿产量,但对CP含量影响不明显;田间杂草、地老虎等既影响苜蓿生长又降低苜蓿CP含量。

The Research of What affects the CP content of Medicago Sativa

It elaborates such factors as genetic character,growing perild,fertilizer applying,field management and cutworm pets affect the CP content of Medicago sativa.The results make it clear that different breeds of Medicago sativa have different amount of CP,which comes down gradually from the growing period to the period of bearing pods;fertilizer applying can raise the yield of Medicago sativa,which can't affect the content of CP obviously;the factors such as the weeds in the field and cutworm pets,etc.can affect the growing of Medicago sativa,but descend the CP content.
