缓释肥在夏季豇豆上最佳施肥模式初探

摘要

通过对夏季种植豇豆基肥比较试验的研究，探讨缓释肥在海南夏季种植豇豆的最佳施肥模式，以提高豇豆夏季生产的产量，补充海南夏季蔬菜的供应，满足海南对夏季渡淡蔬菜的需求。试验结果表明，处理2和处理3分别较对照（普通三元复合肥）增产24.8%和38.5%，增产效果显著。%　　In this article, we studied the optimum application method of slow release fertilizer for cowpea planting in Hainan province by setting different base fertilizer treatments, in order to increase the yield of summer-planting cowpea, supplement the supply of summer fresh vegetable in Hainan and meet the need of Hainan vegetable market. The results showed that, treatment 3 (slow release fertilizer 80 kg/667 m2+organic fertilizer 300 kg/667 m2 ) was the best fertilization model, and the cowpea yield was significantly increased by 38.5% compared with that of the control treatment (ternary compound fertilizer).
