通过田间试验,探讨了不同包膜形式的缓控释肥与普通复合肥对夏玉米生长指标及产量指标的影响。结果表明,缓控释肥较普通复合肥对夏玉米生长效果更好,而且不同包膜形式肥料对夏玉米产量影响程度不同,特别是全降解缓释肥26-8-8复合肥料增产效果最明显,较普通复合肥处理产量提高了14.18%。为缓控释肥在夏玉米上合理施用提供了依据和技术指导。
Field experiments were conducted to investigate the effects of different controlled release fertilizers and conventional compound fertilizers on the growth and yield of summer maize. The results showed that the controlled-release fertilizer had a better effect on the growth of summer maize than ordinary compound fertilizer, and the effect of different forms of coated fertilizer on the yield of summer maize was different. Especially, the effect of 26-8-8 compound fertilizer with full- Obviously, compared with the normal compound fertilizer output increased by 14.18%. In order to control the release of fertilizer in the summer corn on the rational application provided the basis and technical guidance.
