摘要
用不同配方缓释复合肥在玉米播种时一次性基施,比较不同缓释肥对玉米生长发育及产量的影响。结果表明:缓释肥可明显改善糯玉米的营养品质和经济性状,用2号缓释肥玉米产量比常规施肥提高5.95%,氮素利用率提高近10个百分点。
Different kinds of slow-realease fertilezers were used as basal fertilizer and field experi- ments with waxy corn were conducted to compare effects of the fertilizers on growth and yield of waxy corn. The results demonstrated that the slow-realease fertilizers could significantly improve the table quality and economic yield of waxy corn. Compared with the conventional application the application of Slow-Release Fertilizer 2 could increase the corn yield by 5.95% and nitrogen use percent nearly by 10 percentage points. In addition to the advantage of one-time application, application of slow-release fertilizers reached environment-friendly, resource-efficient and production-high multiple objectives.
