摘要
Abstract
A 3414 fertilizer efficiency experiment on sweet potato was carried out in thin layer of red sandy soil.The results showed that N exerted the greatest effect on sweet potato yield,and the minimal effect was P.Calculated with the established simulation equation,the optimum amount of fertilization per 667 m2 was as follows,N 14.36 kg(215.40 kg/hm2),P2O5 2.64 kg(39.60 kg/hm2),K2O 16.21 kg(243.15 kg/hm2),the ratio of N∶P2O5∶K2O was 1∶0.2∶1.13,and the optimum economic yield was 1 563 kg(23 445 kg/hm2).关键词
