The special compound fertilizer for the earth emperor has seven remarkable characteristics by adding chelating humic acid by using the nano-technology of space macromolecule of Chinese Academy of Sciences.
First, stimulate physiological metabolism.
Humic acid contains a variety of active functional genes, which can enhance the activities of catalase and polyphenol oxidase in crops, stimulate physiological metabolism, promote growth and development, and supply adequate nutrients. The stem of the crop is fast and vigorous, the branches and leaves are lush, the photosynthesis is enhanced, the nutrient transfer to the fruiting body is accelerated, and the fruit is colored and ripened ahead of time.
Two, changing the characteristics of fertilizers
Humic acid contains functional groups such as carboxyl group and phenolic hydroxyl group. It has strong ion exchange and adsorption capacity. It can reduce the loss of ammonium nitrogen by ammonium carbonate. Improve the utilization rate of nitrogen fertilizer and reduce the volatilization of urea. Inhibiting soil immobilization of water-soluble phosphorus, transforming available phosphorus into delayed phosphorus, and promoting root uptake of phosphorus.
Humic acid can chelate with insoluble trace elements to form humic acid chelate with good solubility and can be absorbed by crops.
Three. Improved soil structure.
Humic acid can promote the formation of soil mass structure, regulate soil pH, regulate soil water, fertilizer, gas, heat and other conditions, improve soil exchange capacity, achieve acid-base balance. Improve the ability of soil water and fertilizer conservation, promote the activities of soil microorganisms, accelerate the decomposition and transformation of organic matter, promote the release of nutrient elements, facilitate the absorption of nutrients by crops.
Four, enhance the characteristics of stress resistance.
Humic acid can reduce stomatal opening intensity and leaf transpiration of plant leaves, thus reducing water consumption, improving water status in plants, ensuring normal growth and development of crops under drought conditions, and enhancing drought resistance.
Humic acid is mostly amphoteric colloid with high surface activity, which can inhibit fungi, enhance cold resistance of crops, be easily absorbed by cell membranes, change the permeability of cell membranes, and promote the absorption of inorganic nutrients. Control rot, root rot, reduce diseases and insect pests.
Five, improve the quality of seeds
Humic acid can form complex or chelate with trace elements, increase the amount of trace elements from root to leaf or other parts, and regulate the proportion and balance of major elements and trace elements. Strengthen the synthesis of enzymes, such as sugar, starch, protein, fat and vitamins. It can promote the activity of enzymes, transform polysaccharides into soluble monosaccharides, increase the synthesis and accumulation of starch, protein and fat substances, accelerate the primary metabolites from stems, leaves or roots to fruits and seeds, and make fruits plump and thick.
Six, improve nutrient utilization.
The use of humic acid in combination with chemical fertilizer and inorganic water-soluble fertilizer can reduce the amount of chemical fertilizer. The conventional dosage of inorganic water-soluble fertilizer can be reduced by 10%~20%. Thus the effective utilization rate of compound fertilizer can be increased to 3~5 percentage points and the effective nutrient utilization rate can be increased by 18%~31%.
Seven. No additional fertilizer at one time.
Applying soil emperor fertilizer, the crops are not fertile at the beginning, but not in the middle stage. Improve the effective utilization rate of fertilizers, truly reflect the three major effects of quick, medium and long-term, and truly realize one-time fertilization without topdressing.
Soil emperor fertilizer usage amount corn
First, it can be applied to base fertilizer or top dressing:
According to the condition of soil fertility, when making base fertilizer, it is directly applied to the soil, 6-10 cm away from the nest, and 5-7 yuan per nest of fertilizer (two plants).
Base fertilizer is 40-50 kilograms per mu; topdressing is 30-40 kilograms per mu; it can be harvested, ditched, sprayed and sprayed; after use, cover the soil to prevent nutrient loss.
Two, corn seedlings transplanted with a small amount of planting fertilizer:
(a bucket of dung water is supplied with 82 products or a small amount of ammonium carbonate and phosphate fertilizer).
When the maize seedlings grow to about one foot high, 6 - 10 centimeters away from the nest, each nest should be fertilized (two plants) for 5 - 7 yuan. After use, please cover the soil to prevent loss of nutrients.
Soil emperor's fertilizer usage and dosage
Fertilizer for paddy soil:
20 to 25 kg / mu per 3 to 5 days before transplanting. According to soil fertility, 7 to 10 days later, seedlings were applied for topdressing.
Soil fertilizer for rape and wheat:
It can be used as fertilizer for base fertilizer, 3 to 5 yuan / nest, 25 - 30 kg / mu.
Fertilizer for fruit and vegetable dishes:
Used as base fertilizer 50 - 150 kg / mu, if topdressing 50 - 100 kg / mu
