摘要
对在氮、钾充足供应条件下,不同磷肥用量对冬瓜产量的影响进行了研究。研究结果表明,冬瓜产量随着施磷量的增加而上升,当磷肥用量到一定量时产量又下降,最大施磷量为139.86 kg/hm2,最佳效益施磷量为133.6 kg/hm2。
The research studied the yields of white gourd applied with different amounts of phosphate fertilizer under the condition of providing with enough nitrogen and potassium. The results show that, the yield of white gourd increased as the phosphate fertilizer application amount increased, but the yield was declined when the application amount of phosphate fertilizer was 139.86 kg/hm2, and the optimal benefit application amount of phosphorus fertilizer was 133.6 kg/hm2.
