Abstract: In order to exploring cultivation model of high yield of Longdao5, plot trail of different level of density, nitrogen and potassium fertilizers by using orthology regression rotating method. The results were as follows: the sequence of factor which restraining yield of Longdao5 was nitrogen fertilizer >density of cultivation >potassium fertilizer, and cultivation model above 10500 kg/h㎡ were as follow: cultivation density was 19.34 to 24.15 hills/㎡, fertilizing nitrogen was 172.65~180.00 kg/h㎡ and fertilizing potassium was 34.05~67.2 kg/h㎡.
