摘要
氮是提供最佳草生长反应的养分，适当的氮肥施用可以使草皮在更短的时间内形成，并且足够坚固，以便在收获后处理。以结缕草(Zoysia japonica Steud.)为原料，对其生产工艺及营养成分提取进行了研究。处理包括五剂(0,150,300,450和600公斤公顷-1)，分为四次施用，条件是在前一次草皮收获后六个月形成翠绿结缕草草皮。绿宝石结缕草提取养分的顺序为em kg ha -1: N (207) > K (57) > (Ca) > S (27) > P (14) = Mg(14)。
SOD PRODUCTION AND NUTRIENT EXTRACTION BY EMERALD ZOYSIAGRASS WITH SPLIT NITROGEN APPLICATIONS
Nitrogen is the nutrient that provides the best grass growth responses, and proper nitrogen fertilization can enable the formation of sod in less time and firm enough to be handled after harvest. The aim of this study was to evaluate production and nutrient extraction of Emerald zoysiagrass ( Zoysia japonica Steud.) according to the splitting of nitrogen doses. Treatments consisted of five doses (0, 150, 300, 450 and 600 kg ha -1 ) divided in to four applications, provided the formation of Emerald zoysiagrass sods six months after the previous sod harvest. Nutrient extraction by Emerald zoysiagrass occurs in the descending order, em kg ha -1 : N (207) > K (57) > (Ca) > S (27) > P (14) = Mg (14).
