Abstract: The effects of different planting dengsity, N and K fertilizer appling amounts on rice Kendao 12 yields and its components were studied by rotation composite design of quadratic regression in Suihua, Helongjiang Province. The results showed that the highest yield(9 266.8 kg/hm2) is gained with planting density 277 000 hills/hm2, nitrogen 92.36 kg/hm2, phosphorus 37.5 kg/hm2, potassium 75.8 kg/hm2; the highest points eating quality is gained with planting density 305 000 hills/hm2, nitrogen 70.0 kg/hm2, phosphorus 50.3 kg/hm2, and potassium 90.9 kg/hm2.
