在粮食主产区湖北省监利县,以杂交水稻丰优22为试验品种,将中化新型缓释复合肥和袁氏新型缓释复合肥与农民习惯施肥和无氮进行对比,探讨2种缓释复合肥的节肥效果。结果表明,2种新型缓释复合肥在比农民习惯施肥节氮20%前提下,其产量与农民习惯施肥无显著差异,比无氮对照显著增产。
In Jianli County, Hubei Province, the main grain producing region, hybrid rice Fengyou 22 was used as experimental varieties, and compared with the conventional fertilization and nitrogen-free of peasants by using Sinochem new slow release compound fertilizer and Yuan’s new slow release compound fertilizer, Fertilizer release fertilizer effect. The results showed that under the precondition that the two new slow-release compound fertilizers were 20% nitrogenous than the peasants’ fertilization, the yield of the two kinds of new slow-release compound fertilizers did not differ significantly from that of the peasants, and increased significantly compared with the no-nitrogen control.
