Wheat

1. Resistance (activity of various enzymes, phenotype of various organs)

Treatment: Two treatments were set up in the experiment: CK (0 g/L) and FA-K (1.5 g/L), with 2~3 applications during the wheat heading to filling stage. Other measures followed conventional practices.

Figure5. Disease (Fusarium head blight) condition under various treatments.

2. Biomass (increase in biomass of various organs)

Treatment: Two treatment setups were used in the experiment, namely CK (0 g/L) and FA-K (1.5 g/L). They were sprayed once before the tillering stage of wheat, and other operations followed standard procedures.

Figure6. Growth condition of plants and root systems under various treatments.

Result: Compared with the control, spraying fulvic acid significantly increased the root length, leaf length, and width of wheat plants. The growth was more vigorous.

3. Fruit (yield, coloring, internal quality （nutritional components)）

Treatment: Two treatments were set up in the experiment: CK (0 g/L) and FA-K (1.5 g/L), with 2~3 applications during the wheat heading to filling stage. Other measures followed conventional practices.

Figure7. Growth condition of ears and grains under various treatments.

Result: Compared with the control, foliar application of fulvic acid significantly increased fresh weight, plant height, total grain weight, stem length and thickness, harvest index, and yield of wheat.
