| Abstract: | Effects on grass yield and height of Guicao 1 annual rye grass on different density and fertilization were studied. The results showed: in different density and fertilization, grass yield and height of Guicao 1 annual rye grass had marked difference. When fertilization was organic fertilizer 1000kg/667m2 + urea 10kg/667m2 and row pitch 20cm, the Guicao 1 annual rye grass growth speed was fastest, average height was 64.2cm. the grass yield reached highest 3164 kg/667m2 . |
