Abstract:
In this paper,six treatments with different kinds of urea and fertilizer rates were used to clarify the effect of controlled-release urea(CRU)blended with common urea(CU)on agronomic characteristics,yield and quality of soybean(Glycine max).The results showed that CRU blended with CU could promote soybean plant height and soybean dried biomass in different growth stages and the promotion of T6 treatment(CRU 100%)was the highest among all treatments.From R2 to R6 stage,the chlorophyll content increased gradually and LAI increased firstly and then decreased and reached peak at the R4 stage.The chlorophyll content,LAI and yield of fertilizer treatments were significantly higher than control and T4 treatment(CRU50%+CU50%)was the highest among all fertilizer treatments.Meanwhile the blended fertilizer could improve total content of protein and fat.Through comprehensive analysis,CRU50%+CU50% was the best blending ratio.
