摘要：

为筛选出适合晚稻生产的肥料运筹方式,减少肥料成本、增加经济效益,以籼粳杂交晚稻甬优7850为试验材料,研究不同缓释肥料用量及运筹方式对产量、农艺性状及氮素效率的影响。结果表明,等养分处理下,有机无机缓释肥有利于提高有效穗、每穗粒数,667 m2基肥使用30 kg加适量分蘖肥较常规施肥增产4.80%,氮肥农学效率最高;等成本情况下,缓释肥处理氮素减少,产量仍较常规施肥增加1.53%,且氮肥农学效率明显高于常规施肥。双季晚稻有机无机缓释肥以667 m2基肥用量30 kg、总氮量在10.7~12.0 kg为宜。

Abstract:

In order to screen out the fertilizer management methods suitable for late rice production, reduce fertilizer cost and increase economic benefits, the effects of different slow-release fertilizer application rates and management methods on yield, agronomic traits and nitrogen efficiency were studied by using indica-japonica hybrid late rice Yongyou 7850. The results showed that under the same nutrient treatment, organic and inorganic slow-release fertilizer was beneficial to increase the effective panicle and grain number per panicle, and the yield of 667 m2 basal fertilizer with 30 kg and appropriate tillering fertilizer was 4.80% higher than that of conventional fertilization, and the agronomic efficiency of nitrogen fertilizer was the highest. Under the same cost, the yield of slow-release fertilizer was still 1.53% higher than that of conventional fertilization, and the agronomic efficiency of nitrogen fertilizer was significantly higher than that of conventional fertilization. The organic and inorganic slow-release fertilizer of double-cropping late rice should be 667 m2 basal fertilizer with 30 kg and total nitrogen at 10.7-12.0 kg.

Key words: Yongyou 7850, slow-release fertilizer, agronomic traits, agronomic efficiency of nitrogen fertilizer, yield
