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 m^2最高产量为1690.6 kg,N、P_2O_5、K_2O施用量分别为12.2 kg、3.4 kg、16.6 kg;最佳经济效益的N、P_2O_5、K_2O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。
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 / hm^2） when applying dosages of N,P2O5 and K2O were 12. 2 kg /667 m^2（ 183 kg/hm^2）,3. 4 kg/667 m^2（ 51 kg/hm^2） and 16. 6 kg/667 m2（ 249 kg/hm^2） respectively,and the best economic benefit was 1688. 85 RMByuan /667 m^2（ 25 332. 75 RMByuan/667 m^2） when applying dosages of N,P2O5 and K2O were 11. 9 kg /667 m^2（ 178. 5 kg/hm^2）,3. 4 kg/667 m2（ 51 kg/hm^2） and 16. 0 kg/667 m^2（ 240 kg/hm^2） respectively.
