氮肥对黑麦草生长及其内部组分的影响

The Effect of Nitrogen on Ryegrass Growth and Its Internal Components

研究了氮对黑麦草生长及内部组分的影响。结果表明 ,氮对黑麦草的生长有明显的影响 ,在一定氮素范围内随氮用量的增加而增加 ,而过多则反而降低 ;黑麦草体内氮的量及硝态氮的量随施氮量增加而增加 ,而磷、钾的量则随施氮量增加而降低。还初步研究了

The effects of nitrogen on ryegrass growth and its internal components were studied.Nitrogen was found to have significant effects on ryegrass growth.The growth of ryegrass increased with the nitrogen increase and decreased after certain level.The internal nitrogen and nitrate of ryegrass also increased,while the phosphorous and potassium decreased, with the nitrogen applied.The influence of ionic strength on nitrogen effects was also studied in this experiment.
