Abstract
Using four-year and eight-year alfalfa as experimental materials,effects of two levels of humic acid fertilizations on growth and hay yield of alfalfa were studied.The results showed that: humic acid fertilization improved the plant height,node number,distances between leaves,the number of first branch,stem and leaf and hay yeild,especially for eight-year alfalfa;the plant height of seven-year alfalfa humic acid fertilization were higher than that CK and differences between the two treatments came to significant level;the number of first branch of 2000kg/hm2 humic acid fertilization treatment of eight-year alfalfa were higher than that CK and differences between the two treatments came to significant level;hay yields of the first stubble and the whole year of four-year and eight-year humic acid fertilization were higher than that CK and the first stubble differences between the two treatments came to significant level;hay yields of the second
