肥隆是中国科学院沈阳应用生态研究所研制生产的一种新型广谱氮肥长效增效剂。可变氮肥多次施用为一次基施,作物整个生长期不再追肥,提高氮素利用率。本试验研究了该产品对玉米的增产效果,为其合理利用提供了依据。1 材料和方法试验设在海城市农业技术推广中心试验地,地势平坦
Fertilizer is a new type of broad-spectrum nitrogen fertilizer long-acting synergist developed and produced by Shenyang Institute of Applied Ecology, Chinese Academy of Sciences. Variable nitrogen multiple application as a base facilities, the crop is no longer topdressing fertilizer throughout the growth period, improve nitrogen utilization. The experiment studied the product of maize yield increase effect, provided the basis for its rational use. 1 Materials and Methods The experiment was set up in the experimental site of HaiCheng Agricultural Technology Extension Center and the landform was flat
