甘蔗测土配方施肥经济效益的研究

Study on Economic Benefit of Soil Testing and Fertilizer Recommendation of Sugarcane

通过测土配方施肥3414肥效小区田间完整试验,研究金光农场友谊分场采用配方施肥对甘蔗产量的影响。结果表明,适量施用氮、磷、钾肥对甘蔗有明显的增产增收效果。处理N2P3K2产量最高,为5967 kg/667 m2,处理N1P2K1增收最高,为544.620元/667 m2。根据氮、磷、钾肥料效应建立施肥模型,氮、磷、钾最适施肥量分别为34 kg/667 m2、10 kg/667 m2和19 kg/667 m2。

The effect of soil testing and fertilizer recommendation on sugarcane yield was studied by the field plot experiment of fertilizer efficiency of 3414 fertilizer recommendation in Youyi Branch of Jinguang Farm. The results showed that appropriate application rate of N, P, and K has obvious yield and benefit ef- fect on sugarcane. The highest yield was 5967 kg/667 m2 in treatment N2PsK2. The optimum profit was 544.620 yuan/667 m2 in treatment N1P2KI, and the best fertilizer treatment was N2P3K2. The optimum fertilization pattern was established according to the fertilizer efficiency of N, P, K. The optimum fertilizer rate of N, P, K was： 34 kg/667 m2, 10 kg/667 m2, 19 kg/667 m2 respectively.
