中文摘要：

为了探明甜瓜在不同栽培介质下（土壤和基质）对2种包膜材料尿素的适应性,通过盆栽试验利用接触施肥的方式研究了硫包衣尿素（SCU）和树脂包膜尿素（ESN）在不同介质栽培下的释放特性及对甜瓜营养期生长的影响。结果表明：在2种栽培介质下施用同等养分含量的2种包膜尿素可以明显促进甜瓜植株生长,提高甜瓜叶绿素含量、可溶性蛋白质含量及根系活力,且作用效果明显高于普通尿素处理;对比2种包膜尿素,ESN因为前期氮素释放效率大于SCU,故对甜瓜营养期的生长及生理指标的促进作用好于SCU;对比2种栽培介质,2种包膜尿素分别与基质配施下甜瓜的株高、叶面积、叶绿素含量、可溶性蛋白质含量及根系活力均大于与土壤配施。

英文摘要：

In order to explore the adaptability of melon to two kinds of coated urea in different culture media（soil and substrate）, using the method of contact fertilization, a pot experiment was conducted to study therelease characteristics of sulfur coated urea（SCU） and resin coated urea（ESN） in different media and theireffects on the nutritional growth of melon. The results showed that the application of the two kinds of coatedurea with the same nutrient level in two kinds of culture media could significantly promote the growth of melon,increase the chlorophyll content, soluble protein content and root activity, and their effects were significantly higher than that of common urea. Comparing the two kinds of coated urea, the nitrogen release rate of ESN atearly stage was higher than that of SCU, therefore, the effects of ESN on the growth and physiological index ofmelon were better than that of SCU. Comparing the two kinds of culture media, the plant height, leaf area,chlorophyll content, soluble protein content and root activity in substrate with two kinds of coated urea were higher than those in soil with two kinds of coated urea.
