一次性施用缓控释复合肥对春玉米产量及氮素积累转运的影响
The effect of the one-time use of sustained release compound fertilizer on product and the nitrogen accumulation and transport of spring maize
摘要
Abstract
Based on the fiel d experiment, the effect of the one-time use of sustained release compound fertilizer on product and the nitrogen accumulation and transport of spring maize were analysed .The results showed that, compared to conventional fertilization (CK )and one-time use of sustained release compound fertilizer, the product was no significant difference. Dry matters accumulations of flowing period、Nutritive organ DMA transport、Contribution rate to grain was significant difference, Dry matters accumulations of grain was no significant difference.Improving nutrient accumulations at flowering period;NUE、NPFP、NIE have no significant difference, NRE of one-time use of sustained release compound fertilizer significantly higher than CK.,but PPFP、KPFP significantly were lower than CK, between the three dry matters accumulations、nitrogen accumulation and yield do regression equation,there was close correlation.关键词
