Tomato

Treatments: The experiment was set up with seven treatments, namely CK (0g/L), T1 (0.5g/L), T2 (1.0g/L), T3 (1.5g/L), T4 (2.0g/L), T5 (2.5g/L), and T6 (3.0g/L). Fertilizer application was conducted when 80% of the tomato seedlings had grown 6 true leaves, with an application frequency of once every 7 days until maturity. Soil moisture content was controlled at 7% (wilting moisture content) throughout the experiment, with other operations conducted in accordance with standard procedures.

2、Biomass (Growth Quantities of Various Organs).

Treatment: Two treatments were set up in the experiment. One was CK(0g/L), FA-K(1.5g/L), and fertilizer treatment was carried out every 7 days until maturity when 80% of tomato seedlings had 6 true leaves. The other was treated with conventional operation.

Figure2. Growth dynamics of tomato seedlings and early fruiting stages under treatment

Result:Compared to the control, the application of fulvic acid accelerates the growth phases of tomatoes, exhibiting enhanced vigor, characterized by an earlier emergence, earlier flowering, and fruiting.

3、Fruit 

Treatment: Two treatments were set up in the experiment. One was CK(0g/L), FA-K(1.5g/L), and fertilizer treatment was carried out every 7 days until maturity when 80% of tomato seedlings had 6 true leaves. The other was treated with conventional operation.

Figure3. Development and fruiting scenarios of tomatoes under various treatments

Result：In comparison to the control, the utilization of fulvic acid results in a higher number of blooms, larger fruits, and superior coloration in tomatoes.

Result: Compared to the control, the treatment with fulvic acid resulted in higher fruit number per plant, single fruit weight, fruit number per 5 nodes, and sugar content in tomato plants.
