摘要
包膜尿素应用于一品红盆栽的试验研究表明,选用适当的包膜材料,如MgO+PR包膜、MgCO3包膜的尿素,利用其养分释放具有控释性,满足一品红生长所需的氮素营养,一品红的长势得到加强,有效提高了植物对肥料的吸收率。
The Euphorbia pulcherrima pot trials showed that application of urea coated with appropriate controlled-release material ,such as MgO+PR,MgCO3,could fulfill the nitrogen nutrition of Euphorbia pulcherrima growth.The controlled-release capability of controlled-release fertilizer strengthened Euphorbia pulcherrima growth and increased the N use efficiency of plant.
