【Abstract】 In the experiment the design of the quadratic rotation-regression-orthogona ambination was applied to study the effect of different fertihzer ratios and plant densities on kenaf yield.Thus,the quadrie-quadratic equations of all the indexes and their optimum scheme were obtained by means of simulation and sieving by computer And the main, interactive effects were analysed.These results are of theoretical and practical significance for kenaf production.更多还原
