摘要
本文根据1990～1991两年5个试点,不同氮、磷组合,二因素五水平回归设计田间试验测得的参数,建立了夏花生优化配方施肥模型为y=141.1461+5.0989x_N+5.4628x_P-0.1410x_N^2-0.2352x_P^2-0.071x_Nx_P,进而求得,最大施肥量为纯氮15.86kg/亩,P_2O_59.27kg/亩,并对氮、磷互作及单因素的增产效应进行了剖析。
According to the parameters obtained fron the field experiment basecd on 2elements and 5 levels regression design in 5 spots from 1990to 1991,the opimum mixed fertilixer model of summer peanut has been establlished. That was y = 141. 1461 + 5. 0989xN + 5. 4628xP -0. 1410 x2N-0. 2352x2P-0. 071xNPN. According to this equation,the highest fertilizer amount of nitrogen was 15. 86 kg per mu,P2O59. 27kgper mu . At the same time ,the interaction of N and P and single element effect were analysised.
