摘　　要：为探明控释肥、保水剂和壳聚糖的交互效应,以腐熟棉籽壳菇渣+草炭+蛭石(1:1:1,V/V)为基质,采用二次通用旋转设计,研究了控释肥、保水剂和壳聚糖对甜椒穴盘育苗效果的影响。结果表明:适量添加保水剂、控释肥和壳聚糖能有效促进幼苗生长,提高生理活性,增强抗逆能力;保水剂与控释肥之间的互作效应为显著正相关,保水剂与壳聚糖之间的互作效应为正相关,而控释肥与壳聚糖之间的互作效应为负相关,但两者均未达到显著水平。经计算机模拟模型解析,得出该基质条件下甜椒育苗的最佳用量组合为:保水剂4.73~5.22 g·L^(-1),控释肥5.02~5.52g·L^(-1),壳聚糖3.05~3.70 g·L^(-1)。To verify the interaction of controlled release fertilizer, super absorbent polymer and Chitosan, their effects on plug seedlings of sweet pepper were studied by using quadratic general rotary unitized design and applying the three materials in a complex media of mushroom residue compost, peat moss and vermiculite at a ratio of 1：1：1（V/V）. The results showed that： proper application of super absorbent polymer, controlled release fertilizer and Chitosan could promote the growth and physiological activities of seedlings, and strengthen their stress resilience. There was significant positive interaction effect between super absorbent polymers and controlled release fertilizer, Chitosan showed a positive effect with super absorbent polymers, and a negative effect with controlled release fertilizer, both of which being not significant. By using computer simulation and model analysis, the optimum rates for sweet pepper plug seedlings production were super absorbent polymer at 4.73~5.22 g·L^-1, controlled release fertilizer at 5.02~5.52 g·L^-1, and chitosan at 3.05~3.70 g·L^-1.
