Citric acid chelation of single elements

1.Spray on leaves: Iron and manganese are diluted by 1500-2000 times, zinc and magnesium by 1000- 1500 times, copper by 2000-3000 times and titanium by 2500-3500 times, and sprayed continuously for 2-3 times with an interval of 7- 10 days each time.

2.Drip irrigation/irrigation：500- 1000 grams/acre(titanium is 50- 100 grams/acre, copper is 200-300 grams/acre)

It can reduce the loss of fertilizer, improve the utilization rate of fertilizer, thereby reducing the amount of fertilizer and reducing the cost of fertilization. Its absorption and utilization rate is high, which can effectively promote the growth of crops, make the roots of crops developed and the stems and leaves stout and hypertrophy. It can also increase crop yield and improve crop quality.

(1) As a fertilizer synergist: when compounded with compound fertilizer, water-soluble fertilizer and foliar fertilizer, it can significantly improve the utilization rate of fertilizer and promote the faster and better absorption and utilization of nutrients by crops.

(2) As a plant nutrition additive: Citric acid chelation is more conducive to the absorption of trace elements by crops, and can also release free ammonia for rapid absorption by crops.

(3) As a soil improver: Citric acid, as a strong organic acid, can promote the dissolution and release of solidified nutrients in soil, which has a certain promoting effect on improving soil hardening.

(4) As a plant growth regulator: Moderate chelated strength, with good slow and controlled release effect, citric acid and free ammonia are slowly released in crops and directly absorbed by crops, and quick-acting and long-acting coexist.

Strong chelated agent series products have strong chelated ability. After being absorbed by crops, the product morphology always exists in molecular state, and the release of metal ions is slow, so the absorption and utilization rate of crops is low. Citric acid chelate salt series products belong to moderate chelated strength, exist in molecular state under normal conditions, and have all the characteristics of chelated trace elements. After absorption, metal ions and citric acid are slowly released in crops, which can not only greatly improve the absorption and utilization rate of trace elements, but also promote the effective growth and quality improvement of crops.

(1) Green: It is a food-grade raw material, which contains no impurities harmful to crops, and has good solubility, complete water solubility and no precipitation.

(2) Organic: Citric acid is an organic acid, which can be secreted and utilized by plants themselves. Medium chelated strength has high content of trace elements, easy absorption and high utilization rate of nutrients.

(3) Ecology: Decomposition of free citric acid into soil can not only improve the availability of soil phosphorus; The chelated principle can also be used to repair soil heavy metal pollution, which has obvious promotion effect on the improvement of soil ecological environment.

(4) Wide applicability: Not only can it be applied to compound fertilizer, water-soluble fertilizer and foliar fertilizer, but it can also be mixed with pesticides and regulators.
