摘要
在崆峒区旱地条件下,通过胡麻"3414"肥料肥效试验,建立胡麻产量(Y)与N、P、K肥之间的回归方程,得出适合崆峒区旱地胡麻生产的最佳施肥模式,即崆峒区旱作条件下胡麻生产最佳施肥量为N 131.3 kg/hm2、P2O550.0 kg/hm2、K2O 83.1 kg/hm2,此时的胡麻预计产量为1 035.4 kg/hm2。
By using ＂3414＂ fertilizer experiment method in arid land of Kongtong district,regression equation between Linum usitatissimum yield and nitrogen,phosphorus,potassium was established.The best economic fertilization dosage,the appropriate ratio among the three essential fertilizer on the Linum usitatissimum were gained.The best economic fertilization dosage in arid land of Kongtong district was N 131.3 kg/hm2,P2O5 50.0 kg/hm2,K2O 83.1 kg/hm2,the best economic Linum usitatissimum output was 1 035.4 kg/hm2.
