Effects of fertilization on some physiological traits of Chinese fir seedling and soil nutrient

Abstract: In foreign soil seedbeds , urea (N), calcium superphosphate (P), potassium chloride (K) and decayed cake manure (M)were applicated for 2 weeks before planting Chinese fir year-seedling in March .Application rate was as follows :A plot , check ;B , N 50.0 gm -2 , P 45.0 gm -2 , K 30.0 gm -2 ;C , M 600.0 gm -2 ;D , N 25.0 gm -2 , P 22.5 gm -2 , K 15.0 gm -2 , M 300.0 gm -2 ;E , M 600.0 gm -2 , N 50.0 gm -2 , P 45.0 gm -2 , and K 30.0 gm -2 .The results of analysis in September indicated that fertilization was of great value for improving biomass , root vigor and chlorophyll content of Chinese fir seedling .In comparison with A , biomass , root vigor and chlorophyll content of seedling in B , C and D were 2.05 , 1.60 , 2.11 times , 1.24 , 1.75 , 1.44 times , and 1.35 , 1.40 , 1.52 times, respectively .E was of great effect for improving physiological function of seedling .Fertilization increased not only land capability , but also available nutrient of soil.
