盆栽试验结果表明 ,喷施植物动力 2 0 0 3(简称PP2 0 0 3)能改善植物生长状况 ,促进对氮肥的利用 ,氮肥利用率 (示踪法 )从对照的 2 6%提高到 4 2 % ,效果明显
The results of pot experiment showed that spraying plant dynamics of 20000 (referred to as PP2 0 0 3) could improve the plant growth status and promote the use of nitrogen fertilizer. The nitrogen use efficiency (tracer method) increased from 26% to 42 %, The effect is obvious
