摘要
采用不完全试验设计,在温室对花盆种植的苜蓿施用氮、磷、钾肥料,研究其对牧草干物质产量的影响.结果表明:用种子播种所建植的苜蓿,在播种当年追施氮、磷、钾肥可以显著(p<0.05)提高苜蓿干草产量和植株高度,且随着氮肥施入量的增加,干草产量呈上升趋势;磷、钾、肥以中等施入量(120 kgP2O5/hm2,200 kg K2O/hm2)增产效果较好.
An experiment was study the effect of Nitrogen （N）, （DM） yield and height of alfalfa, carried out in a greenhouse of China Agricultural University in 2001 to Phosphorus （P）, Potassium （K） fertilizsers applied on the dry matter establishing the first year with seed of ＂Queen＂ alfalfa in flowerpot with a incomplete randomized design. The result showed that the DM yield and height of alfalfa increased significantly （p〈0.05） compared with control groups in all treatments, and the DM yield was gained more with N fertilizers maximal application, and P, K fertilizers moderate application.
