    Experiment of “3414” fertilizer efficiency of sweet potato

      摘要
    • 摘要: 应用"3414"试验设计方案进行甘薯田间肥效试验,结果表明:每667 m2最高产量为1690.6 kg,N、P2O5、K2O施用量分别为12.2 kg、3.4 kg、16.6 kg;最佳经济效益的N、P2O5、K2O施用量分别为11.9 kg、3.4 kg、16.0 kg,最佳经济效益为1688.85 元。

       

      Abstract: A fertilizer efficiency test was carried out in sweet potato field by using "3414" experimental design. The results showed that the maximum yield of sweet potato was 1690.6 (25 359 kg/hm2) when applying dosages of N, P2O5 and K2O were 12.2 kg/667 m2 (183 kg/hm2), 3.4 kg/667 m2(51 kg/hm2) and 16.6 kg/667 m2(249 kg/hm2) respectively, and the best economic benefit was 1688.85 RMByuan/667 m2 (25 332.75 RMByuan/667 m2) when applying dosages of N, P2O5 and K2O were 11.9 kg/667 m2(178.5 kg/hm2), 3.4 kg/667 m2(51 kg/hm2) and 16.0 kg/667 m2(240 kg/hm2) respectively.
