2013年赤峰市玉米“3414”肥料效应田间试验报告
“3414”fertilizer response experiment on corn in 2013 in Chifeng city
摘要
Abstract
This paper introduced the field experimental results of “3414” fertilizer response to corn in 2013 at chifeng city. The theoretical optimal fertilization amount of N,P and K were N 18.59 kg/667m2、P2O5 12.23 kg/667m2﹑K2O 6.72 kg/667m2. The optimal yield was 954.66 kg/m2 under the ratio of pure N∶P2O5∶K2O (1.00∶0.66∶0.36).The recommendation fertilization amounts were urea (N,460 g/kg) 40.41 kg/667m2,calcium superphosphate (P2O5,120 g/kg) 101.92 kg/m2 and potassium sulfate (K2O, 500 g/kg) 13.44 kg/667m2.关键词
