摘　　要：为探讨油占8号的最佳施肥量,进行本试验。结果表明:在一定范围内,N、P、K的增加对油占8号的产量有正效应,对其影响的敏感性为N>K>P,当超过一定水平,N、P、K对其产量有负效应,这种影响表现为N>P>K。N、P、K配施的比例由土壤养分供应量决定,对本地区的土壤建议施用量分别为N200kg/hm2、P2O5100kg/hm2、K2O190kg/hm2。This Experiment is conducted to seek the best fertilizing amount of Youzhan 8. The result shows that within some amount the increments in N, P and K have positive effects over Youzhan 8 yield, and the sensitivity of effects is N〉K〉P, and beyond the amount, the N, P and K have negative effects over its yield as N〉P〉K. The ratio of N, P and K is determined by the soil nutrient supplies, and the suggestion for local fertilizing amount of N, P and K is 200kg/hm^2, 100kg/hm^2, and 190kg/hm^2 Respectively.
