肥隆是沈阳应用生态研究所和沈阳新型肥料技术研究推广中心研制生产的 ,它可使氮肥的肥效期由原来的 30～ 5 0 d延长到 90～ 110 d,提高氮肥利用率 8%～ 12 %,使作物平均增产 10 %以上 ,在产量相当的情况下 ,应用肥隆可节约肥料 2 0 %。为探讨肥隆在玉米上的应用效果 ,1999年双 Fertilizer is developed and produced by Shenyang Institute of Applied Ecology and Shenyang New Fertilizer Technology Research and Extension Center, which can prolong the fertilizer application period of nitrogen fertilizer from 30 ~ 50 days to 90 ~ 110 days and improve the utilization rate of nitrogen fertilizer by 8% ~ 12 %, So that the average yield of more than 10% of crops, in the case of a considerable yield, the application of fertilizers can save fertilizer 20%. In order to explore the effect of fertilizer on the application of corn, double in 1999
