【摘要】 试验结果表明,沙壤土碱草地上,施氮肥比施氮磷肥混施或施复合肥增产效果显著。而氮肥中又以施硝酸铵效果最好。667m2施硝酸铵10 kg时增产甘草50.0 kg,比对照增产76.8%,施肥时期以6月5日和6月20日效果较好,分别增产0.8%和72.3%。草地施肥不仅要考虑土壤、植被、产草量、肥料种类、施肥时期及牧草的生长发育阶段,还要注意水分条件,一般在降雨后或施肥后灌水最好。更多还原

【Abstract】 The results show that the sand loam base on the grass,nitrogen fertilizer than mixed phosphate compound fertilizer production facilities or significant.Shi again in nitrogen and ammonium nitrate was the most effective.667 ㎡ at 10kg ammonium nitrate production facilities licorice 50.0kg,increasing 76.8 percent over the control,fertilizer application period to June 5 and June 20 effective,respectively,increasing 72.3 percent and 0.8 percent.Lawn fertilizer not only to consider the soil,vegetation,yield,the type of fertilizer,fertilizer and grass period of growth and development stage,we should also pay attention to water conditions,the general in the rain after fertilization or irrigation best.更多还原
