　　为了研究保水剂与尿素互作对氮素的缓释效果，采用盆栽试验，通过分析不同生育期土壤碱解氮的变化，探讨并研制适当配比的保水缓释肥提供理论依据。结果表明：在玉米生育前期，保水剂能够吸持速效态氮，使其不会过快地提供土壤氮素供作物吸收；到生育中后期，土壤碱解氮含量比较平稳，说明保水剂能不断地释放氮养分，使其转化为速效态供玉米吸收；通过方差分析、显著性检验，主处理（保水剂）、副处理（尿素）及主副处理的交互作用，在苗期和收获期碱解氮均达到极显著水平，从而得出保水剂起到缓/控释养分的效果，满足了玉米对氮养分的需求，其中，以处理B3N2的互作效应最好，其次为处理B3N3。

In order to study the interactions of super absorbent polymer (SAP) and urea nitrogen in slow-release effect, using pot experiment, through analysis of the varieties of alkaline nitrogen in different growth period and all these provided the theoretical basis for an appropriate ratio of water-retention sustained-release fertilizer. The results showed that: in the early growth of corn, super absorbent polymer could hold available nitrogen, so that it would not be too fast to provide soil nitrogen for crop absorption; in the later growth period, soil available nitrogen content relatively smooth, description of these that super absorbent polymer could continue release of nitrogen into the available for uptake by maize; through variance analysis and test of significance, the main processing (SAP), secondary processing (urea) and main and auxiliary treatment interaction, in seedling stage and harvest stage alkali hydrolysable nitrogen reached very significant level, thus, super absorbent polymer had the capability of slow/controlled release of nutrient to meet the corn on nitrogen nutrient requirements, wherein, to handle the B3N2 interaction effect best, followed by processing B3N3.
