摘要
进行了海南早稻"3414"肥效试验,结果表明:三元二次方程差异达到极显著水平,预测最佳施肥量的农艺方案为:施纯N147.90 kg/hm2、P2O5 127.95 kg/hm2、K2O 138.75 kg/hm2;一元二次回归方程只有氮肥回归方程差异达到显著水平,预测最佳施肥量的农艺方案为:施纯N 211.6 kg/hm2、P2O5 108 kg/hm2、K2O 136.4 kg/hm2。
In this paper,the field experimental of ＂3414＂fertilizer response to rice was introduced.It indicated extre-remarkable level in ternary quadratic equation,but significant level in N equation of single quadratic equation.The results showed that and the best economic application of fertilizer was obtained by ternary quadratic equation,which was N 147.90 kg/hm2,P2O5 127.95 kg/hm2,K2O 138.75 kg/hm2,and single quadratic equation of fertilizer effect was N 211.6 kg/hm2,P2O5 108 kg/hm2,K2O 136.4 kg/hm2.
