Effect of Different Water-soluble Fertilizers on the Yield and Quality of Tasty Tomato
In order to screen for suitable water-soluble fertilizers that promote fruit growth and development of high-quality tomato after fruiting in Miyun area,this experiment selected three different water-soluble fertilizer varieties with different nitrogen phosphorus potassium ratios for analysis by measuring indicators such as tomato plant growth,fruit quality,and yield.The results showed that in terms of fruit quality,treatment 2(with nitrogen,phosphorus,and potassium content of 15-5-35)had the best water-soluble fertilizer effect,the plant height was the highest,and the plant growth rate was 2.33 cm/d.The mass of a single fruit was 75.95 g,the yield was 4 145.39 kg/667 m2,the fruit sugar acid ratio and vitamin C were 6.66 mg/100 g and 22 mg/100 g,respectively.In terms of economic benefits,treatment 3(15-5-30)had the highest production to investment ratio,while treatment 1(CK)had the lowest production to investment ratio.Based on comprehensive analysis,it was recommended to apply water-soluble fertilizers with nitrogen,phosphorus,and potassium contents of 15-5-35 after high-quality tomato yields in Miyun area.
