Controlled-release fertilizer combined with nutrient synergist significantly increased tomato yield and quality
The effects of controlled-release fertilizer combined with nutrient synergist on the growth,yield and quality of the tomato were studied by field experiments with the tomato(Lycopersicon esculentum Mill.)variety Ruifei as the experimental material.The re-sults showed that the combination of controlled-release fertilizer and nutrient synergist could significantly increase stem diameter(P<0.05).Compared with conventional fertilization,controlled-release fertilizer and controlled-release fertilizer combined with nutrient synergist could significantly improve tomato quality,the soluble solids content of tomato fruit had an increasing trend,the soluble sugar content and vitamin C content were significantly increased(P<0.05),and the color and hardness of tomato fruit were also improved.Compared with conventional fertilization,controlled-release fertilizer and controlled-release fertilizer combined with nutrient synergist could effectively improve tomato yield and economic benefits,the yield increased by 12.7％and 29.2％,respectively,and the net profit increased by 36 500 yuan/hm2 and 77 200 yuan/hm2,respectively.In conclusion,controlled-release fertilizer combined with nutrient synergists could increase tomato yield and efficiency,and had important practical value in achieving light and simplified production.
