| 摘 要： | 采用二因素五水平正交组合设计方案,建立回归模型并进行效应解析后表明,肥对新麦草种子产量的效应大于水;水对新麦草种子产量作用为负效应;但是水肥耦合对新麦草种子产量的效应为协同效应.按照新麦草种子生产水肥因子的等效点方程可调整水肥因子.新麦草种子最高产量的施肥量为179.93 kg/hm2 (其中N:105.84 kg/hm2;P2O5:74.09 kg/hm2)～195.89 kg/hm2 (其中N:115.23 kg/hm2;P2O5:80.66 kg/hm2), 灌溉量为60.52～131.81 mm. |

| Abstract: | This paper presents an analysis on the model that was established based on a bin-factor orthogonal contract block field experiment design of P.juncea seed yield.The results showed that the effect of fertilizer on yield is higher than that of irrigation,with irrigation shown to have a negative-effect.However,the coupling effect of irrigation and fertilizer was shown to have a synergistic effect on the yield.The assigned value of the factors according to the equilibrium equation,and the optimum range for the factors is given: the range for fertilizer is 179.93 kg/hm~2(N:105.84;P_2O_5:74.09)-195.89 kg/hm~2(N:115.23;P_2O_5:80.66),the range for irrigation is 60.52-131.81 mm. |
