| Abstract: | The mathematical model of fertilization for earlier cucumber was studied in lower altitude areas in Guizhou Province, by taking the N,P.K as factors and the yield of cucumber as objective function in the quadratic regression design of 341g. The results showed that the optimal proportion of fertilizer was N 201.75 kg/hm^2, 17205 121.05 kg/hm^2 and K2O 321.15kg/hm^2, the yield could reach 79 435.05 kg/hm^2. |
