Humic acid fertilizer refers to the use of peat soil, coal slime and weathered seam coal to produce products with a lot of humic acid and nitrogen, phosphorus, potassium and some nutrients needed for crop growth and development by using different lean production methods. The effect in agriculture is mainly to stimulate the growth and development of crops, improve the soil layer, enhance nutrients, and enhance the theme of soil microorganisms, etc. So what is the role of humic acid fertilizer? What is the use method of humic acid fertilizer?

How to use humic acid fertilizer:

1. Seed soaking: Seed soaking can improve the seedling emergence rate, germinate in advance, and improve the working ability of the hair of the seedlings. The general seed soaking concentration is 0.005-0.05 percent, the general seed soaking time is 5-10 hours, and the husk seeds such as rice and cotton wool are 2 Ten 4 hours.

2. Root soaking: rice, sweet potato, etc. can be soaked with sodium humate or potassium humate aqueous solution before planting, with a concentration of 0.01-0.05 percent. After soaking, it mainly shows that the hair is fast and the survival rate is high.

3. Spraying: The general concentration is 0.01-0.05 percent aqueous solution, spray 2-3 times during the flowering period of crops, and the spray volume is 50 liters of solution per 1 mu. The spraying time should be taken at 2-4 o'clock in the afternoon. it is good.

4. Base fertilizer: solid humic acid fertilizer (such as ammonium humate, etc.), generally 100-150Kg per 6 mu. When humic acid aqueous solution is used as base fertilizer, the concentration is 0.05-0.1%, and the amount used per 6 mu is 250-400 liters Solution, can be mixed with farmyard fertilizers, can be applied in furrows or holes.

5. Fertilization: Before the seedling stage and heading stage of crops, use 250 liters of solution with a concentration of 0.01-0.1 percent per 6 mu, and irrigate around the rhizomes of the crops. The paddy field can be used with water injection or sprinkled on the river surface, which can improve the seedlings. , Prosperous seedlings, promote growth and development and other effects.
