摘要
进行花生氮磷钾3414田间试验,结果表明:磷肥增产效应居首位,增产率为30.77%。三要素的增产效果与土壤养分含量有关;在试验条件下,坑北村花生每667 m2最佳经济效益施肥量分别为N 7.50 kg、P2O53.67 kg、K2O 8.57 kg。
A field trial on N, P and K efficiency of ＂3414＂ fertilizer to peanut was carried out. The results showed that the yield-increasing effects of three fertilizers were related to soil nutrient content, among them P ranked the first and the yield increased 30. 77%. Under the condition of this experiment, the fertilizer rate of the optimum economic benefit per 667m^2 of N, P2O5 and K2O were given as 7.50, 3.67 and 8.57 kg（ 112. 5, 55.05 and 128. 55 kg/hm^2） respectively.
