　　为了研究土壤水分对水冬瓜包膜肥料养分释放性的影响，以水冬瓜果油为包膜材料，制备包膜肥料，采用温室盆栽试验方法，研究土壤水分对包膜肥料释放性。在观察养分溶出率期间，保持盆栽土壤温度在25℃。结果表明：温度和土壤含水率对水冬瓜包膜尿素累计溶出率有较大的影响，温度越高，累计溶出率越大；初始含水量越大，水冬瓜包膜尿素养分累计溶出率增加越快，包膜尿素日释放速率也随着越大。得出水冬瓜果油包膜尿素养分释放期(d)与土壤含水率(w)的关系曲线为线性关系，d=287.8-3.53w，r=0.99这一结论。

In order to study on the nutrient released period with the soil moisture on released of nutrient from coated urea, this text studied coated material as the Idesia polycarpa var. vestita oil of the nature resources (to distillation from the fruit of tree) and preparation the coated-released-fertilizer, using the greenhouse experiment method, study on the imitation of dynamics process with the soil moisture and the nutrient released period on released of nutrient from coated urea and the temperature was kept at 25℃ in the pot. The results showed that, there were obvious effect of soil temperature and different soil moisture on the rate of nutrient released from coated urea with Idesia polycarpa var. vestita oil as coating material;the rate of nutrient released increase with increased of temperature and the rate of nutrient released increased with increased of rate of soil moisture and the accumulated nutrient released increased with increased of rate of soil moisture. There was obvious relation of line type with nutrient released period (d) and rate of soil moisture (w):d=287.8-3.53w, r=
