摘要
采用田间试验法,研究了磷肥对不同产田夏玉米性状、产量及产量构成因素的影响,旨为夏玉米合理施用磷肥提供科学依据。结果表明:高、中、低产夏玉米田最佳经济施磷量分别为50 kg/hm2、52 kg/hm2和47 kg/hm2。
The effects of phosphorus fertilizer on the characters,yield and yield components of summer corn with different yield were studied.The results showed that the optimum fertilization rate of high-yielding,medium-yielding and low-yielding field was 50 kg/hm2,52 kg/hm2 and 47 kg/hm2,respectively.
