Analysis on Fertilizer Efficiency of Soil Available Phosphorus of Summer Corn with Different Yield

Jinran Wang

Abstract

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.
