草坪缺肥会出现草色发黄、提前休眠、抗逆性减弱、难以返青等现象。草坪施肥是草坪管理的重要环节之一。据研究,草坪草对N、P、K的需求量最高。N是草坪草最为关键的营养元素;P可调节草体内代谢,并能增强草坪草的抗逆性;K可增强草坪草对不良环境的适应性。本试验就NPK肥配比对草地早熟禾生长的影响进行了研究。
Turf lack of fertilizer will appear yellow grass color, early dormancy, reduced resistance, it is difficult to return green and so on. Lawn fertilization is an important part of turf management. According to the research, turfgrass has the highest demand for N, P and K. N is the most important nutrition element of turf grass; P can regulate the metabolism of turfgrass and enhance the resistance of turfgrass; K can enhance the adaptability of turfgrass to the adverse environment. In this experiment, the effect of NPK fertilizer on the growth of Kentucky bluegrass was studied.
