摘　　要：研制了一种低成本缓释化肥,并对其养分缓释性能及养分释放规律进行了研究。实验结果表明:蒸馏水的作用无法使该缓释肥料中的大分子物质水解而释放出养分,而土壤则能使其养分基本释放,这说明该缓释肥料中的高分子物质能够在土壤中降解,作为化肥施入土壤后在一段时间内能够降解成能被植物吸收的小分子营养物质。A lower cost slow-release fertilizer is prepared, and its slow-release capability and release characteristics of nutrient content are studied. The results show that big molecules in this slow-release fertilizer can＇t release nutrient content under hydrolysis of water, but can release mostly in soil, which indicates that big molecules in this slow-release fertilizer can be degraded to additive content absorbed by plants after fertilization into soil.

关 键 词：缓释化肥 低成本 缓释性 养分释放规律
