氮肥对两个品种多花黑麦草生长和生理的影响
Effect of Different Nitrogen Fertilization Levels on Growth and Physiology of Two Annual Ryegrass Cultivars
摘要
Abstract
Under the field experiment conditions,through the determination of main growth and physiological indexes,the effect of different nitrogen fertilization levels on the growth and physiology of 2 annual ryegrass cultivars was discussed.It shows that if the application of nitrogen fertilizer is in an appropriate range,the tiller number,plant height and yield of annual Ryegrass will increase with nitrogen level increasing,and the highest yield of 2 varieties of nitrogenous fertilizer quantity is the same 300 kg/hm2 ; the chlorophyll content of 2 varieties increase along with nitrogen fertilizer; at the same time,nitrogen fertilizer applied will ignite the resistance defense system of the ryegrass,and the tolerance of different varieties for nitrogen fertilizer is different,Maximus being stronger than Hercules.关键词
