Abstract:With the design of combination quadratic recursive with obverse cross circumrotate,the experiment in the optimum mathematics model of potato production with high grade and high yield was conducted. Based on analysis of the model,two models of high yield and high efficiency were worked out through the simulated test by computer. The model of the ratio of output to cost being more than 1.69 and the pure proceeds being more than 4 000 yuan/hm2 was that the planting density range was from 40 312.5 to 42 975 per hm2,the dosage range of pure N was from 45.045 to 52.537 5 kg/hm2,the dosage range of P2O5 was from 126.495 to 143.505 kg/hm2 and the dosage range of K2O was from 147.015 to 160.99 kg/hm2. The model of the ratio of output to cost being more than 2 and the pure proceeds being more than 4 500 yuan/hm2 was that the planting density range was from 39 697.5 to 43 807.5 per hm2,the dosage range of pure N was from 42.323 to 51.57 kg/hm2,the dosage range of P2O5 was from 124.695 to 145.305 kg/hm2 and the dosage range of K2O was from 133.515 to 165.848 kg/hm2.
Keywords:High yield  High efficiency  Mathematics model  Manure scheme
