在单因子试验的基础上,从各因子的生长适宜区间内分别选取10个盐度梯度、10个光照梯度和10个温度梯度,以及10个NO3-N浓度梯度、10个NH4-N浓度梯度和10个PO4-P梯度,采用均匀设计方法,考察各因子及其交互作用对菊花江蓠N、P吸收速率的影响,通过回归分析得到:温度、光照与NO3-N、NH4-N间存在着很明显的交互作用关系,它们共同作用影响着海藻对NO3-N、NH4-N的吸收速率;对PO4-P的吸收速率,仅受到温度及PO4-P共同作用的影响;而对TIN及PO4-P的吸收却都受到N×P交互作用的影响。
Based on the single-factor test, 10 salinity gradients, 10 light gradients and 10 temperature gradients were selected from the appropriate growth intervals of each factor, and 10 NO3-N concentration gradients, 10 NH4-N concentration gradients And 10 PO4-P gradients. The uniform design method was used to investigate the effect of various factors and their interaction on the absorption rate of N and P of Chrysanthemum morifolium. By regression analysis, the results showed that there was a correlation between temperature, light and NO3-N and NH4-N The interaction between NO3-N and NH4-N was influenced by their interaction. The absorption rate of PO4-P was only affected by the temperature and PO4-P interaction. However, the effect of TIN and The absorption of PO4-P is affected by the N × P interaction.
