Abstract:: The effects of seven types of substrates, three fertilizer level on ryegrass chlorophyll content and root growth situation with the Lolium perenne to find its suitable substrates and fertilizer levels were examined. The results showed that:impact of substrates on the chlorophyll content of ryegrass was significant;with the increase of fertilizer, chlorophyll content of ryegrass increased firstly and then decreased, impact of fertilization on chlorophyll content of ryegrass was not significant;impact of substrates on root length of ryegrass was significant;fertilization level had little effect on ryegrass root length;substrates effected ryegrass root activity significantly;impact of fertilization on ryegrass root activity was not significant. In the A3 fertilization application, the ryegrass root activity in substrates of NO. Ⅴ, Ⅵ, Ⅶ was much higher than in other substrates. The best combination of substrates and fertilizer levels for the Lolium perenne is combining substrates of NO. Ⅶ with fertilizer levels of A3.
