通过“3414”肥料效应试验,建立肥料效应方程,探索番茄最佳施肥配比方案,为在紫色土上种植番茄提供科学依据。结果表明:测土配方施肥对番茄的增产效果明显,研究区番茄纯N、P2O5、K2O的最佳施肥量分别为32.5、12.5、13.5 kg/亩,纯N、P2O5、K2O的最佳配比为1∶0.4∶0.4。平均每生产100 kg番茄需纯N、P2O5、K2O分别为1.38、0.16、0.5kg。番茄对氮、磷、钾肥的利用率分别为33%、13%、21%。
Through “3414” fertilizer effect experiment, the fertilizer effect equation was established to explore the optimal proportioning plan of tomato and provide scientific basis for planting tomato on purple soil. The results showed that the effect of soil testing and fertilization on tomato yield was obvious. The best fertilization rates of pure N, P2O5 and K2O in tomato were 32.5, 12.5, 13.5 kg / mu, pure N, P2O5 and K2O respectively 1: 0.4: 0.4. The average production of 100 kg of tomato pure N, P2O5, K2O were 1.38,0.16,0.5 kg. Tomato nitrogen, phosphorus and potassium fertilizer utilization rates were 33%, 13%, 21%.
