Abstract：With the design of the current rotation regression combination,the high yield mathema tical model on watermelon was studied,in which N,P and K were supplying factors,watermelon yield was objective funcation. According to the objective funcation,the most suitable amounts of fertilization for yield were as follows:N 210kg/ha,P 2O 5 80kg/ha,K 2O 175kg/ha,under this circumstance,the yield was 47175.9kg/ha,the profit was 26 910.5 yuan/ha. In addition,the single factor effects of N,P,K and their interact...
