| Abstract: | A mathematical model was built by investigating the relation between N, P, K fertilizers and transplant density for improving the yield of Qianyou 16 effectively. The results showed that the comprehensive cultivation technique for 200 kg/667m^2 of Qianyou 16 is including 7000-8000 plants/667m^2 of density, 20 kg of urea, 40 kg of calciums supper phosphate and 10kg of potassium chloride per 667m^2 on the middle fertility soil at an elevation of 800 m more or less. |
