The functions of the components and elements of the water soluble fertilizer are explained in principle as follows:
humic Acid (HA) is a group of natural hydroxy aromatic carboxylic acids, and is mainly composed of carbon (C), hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), and is a macromolecular organic substance formed and accumulated by animal and plant remains through decomposition and conversion of microorganisms and a series of processes of geochemistry. The chemical structure of the humic acid is not clear up to now, the basic unit of the molecular structure of the humic acid is generally considered to be aromatic ring and aliphatic ring with side chains and small condensation degree, and also has heterocyclic ring, and active groups such as carboxyl, hydroxyl, carbonyl, quinonyl, amino, sulfonic group, methoxyl group and the like are connected around the basic unit.
Physiological role of nitrogen (N): nitrogen is a component of nucleic acids, coenzymes, phospholipids, chlorophyll, cytochromes, phytohormones (CTK), vitamins, and the like. Is a constituent element of protein and nucleotide, participates in the formation of chlorophyll, and improves photosynthesis.
Physiological role of phosphorus (P): phosphorus plays an important role in cell division and flowering and fruiting. Has good effect on improving stress resistance (disease resistance, cold resistance and drought resistance). Promote the development of root system, especially the growth of lateral root and fine root. Accelerate flower bud differentiation, and promote flowering and maturation.
Physiological effects of potassium (K): the content of the plant in the plant exceeds phosphorus, the high-yield crops also exceed nitrogen, the plant is mainly in an ionic state, the plant is an activator of a plurality of enzymes (more than 60 enzymes) in organisms, and the enzyme is an important component for forming the osmotic potential of cells, regulating the opening and closing of stomata, promoting photosynthetic phosphorylation and promoting the transportation of assimilates.
Physiological effects of boron (B): boron influences the development of reproductive organs and the elongation and division of cells in crops, and plays an important role in flowering and fruiting.
Physiological role of zinc (Zn): is a component and an activator of various enzymes, and more than 80 zinc-containing enzymes are found to participate in the synthesis of auxin.
The humic acid of the water-soluble fertilizer is combined with various nutrient elements, so that the water-soluble fertilizer not only provides nutrients for crops in time, but also has obvious effects on improving soil, stimulating the growth of the crops, enhancing the efficiency of fertilizers, enhancing the stress resistance of plants, improving the quality of agricultural products and the like; after the fatty alcohol-polyoxyethylene ether is added, the spreading performance of the fertilizer on the leaf surfaces is improved, the absorption rate of nutrients is improved, and in addition, when the humic acid is sprayed on the leaf surfaces, the stomata of the leaf surfaces of plants can be closed, and the drought resistance effect is achieved.
Humic acid has higher salt base exchange capacity, can reduce the volatilization loss of nitrogen and improve the effective nitrogen content of soil. Generally, nitrogen fertilizer has strong volatility and low utilization rate, and can improve the absorption utilization rate by 20-40 percent when mixed with humic acid; humic acid can stimulate the activity of soil microorganisms to be increased, and the mineralization speed of organic nitrogen is improved, so that the content of quick-acting nitrogen in soil is improved; research shows that humic acid has obvious decomposition effect on phosphorite and has protective effect on available phosphorus, thus reducing fixation of soil on available phosphorus and promoting phosphorus absorption at crop roots, thereby improving the utilization rate of phosphate fertilizer; the functional group of humic acid can absorb and store potassium ions, prevent the potassium ions from losing along with water in sandy soil and soil with strong leaching property, prevent cohesive soil from fixing potassium, has a corrosion effect on minerals such as potassium-containing silicate and potassium feldspar, and slowly decomposes the minerals to facilitate the release of the potassium, so that the humic acid with the content of the soil quick-acting potassium can perform a chelation reaction with slightly soluble trace elements to generate a humic acid trace element chelate which has good solubility and is easy to be absorbed by crops, is favorable for the absorption of roots or leaf surfaces, and can promote the transfer of the absorbed trace elements from the roots to overground parts, and the function is not possessed by inorganic trace element fertilizers.
Moreover, as humic acid contains various functional groups, after being activated, the humic acid becomes a high-efficiency bioactive substance which has stimulation effect on the growth and development of crops and the physiological metabolism in vivo, and the characteristic is not possessed by common fertilizers. The activated humic acid in the water soluble fertilizer has obvious effect of promoting the growth of various crops by adopting the modes of seed soaking, root dipping, spraying and irrigating, base fertilizer making and the like according to certain concentration. If the germination of seeds can be accelerated, the emergence rate is improved, the germination is particularly remarkable in early spring and low temperature, the seeds can germinate 1 to 3 days in advance, and the emergence rate can be improved by 10 to 30 percent; promote the development of root system, and greatly enhance the capability of crops for absorbing water and nutrients. On the basis of sufficient nutrient supply, humic acid can ensure that overground part of the plant can grow vigorously, and has the effects of increasing effective fraction, spike grain number, thousand grain weight and void fraction, thereby improving the yield; the fruit is colored and ripened in advance, and the product quality is improved. Particularly, humic acid has a remarkable promotion effect on plant respiration, and is called as a 'respiration fertilizer' in the literature, and is more remarkable in an anoxic environment.
After the fatty alcohol-polyoxyethylene ether is added, the opening degree of the air holes of the plant leaves can be reduced by spraying the fatty alcohol-polyoxyethylene ether on the leaves, the transpiration amount of the leaves is reduced, the water consumption is reduced, the water content in the plant body is improved, and the water content of the leaves is improved, so that the drought resistance of crops is improved; can also improve the chlorophyll content and promote photosynthesis, and is very important for the accumulation of substances and the improvement of thousand seed weight. In addition, the water-soluble fertilizer also has the functions of enhancing the cold resistance of crops and improving the immunity of the crops, for example, winter wheat in most regions in the north of China is generally damaged by winter due to the frequent occurrence of 'late spring cold', and after the water-soluble fertilizer containing humic acid is applied, the cold resistance of wheat can be effectively improved, and the freezing damage is reduced to different degrees. A large number of research experiments prove that the water soluble fertilizer has obvious effects of preventing, controlling, inhibiting bacteria and sterilizing rot, lobular and yellow leaf diseases of fruit trees, downy mildew of cucumber, anthracnose and virus diseases of hot pepper and the like. Moreover, experiments show that under the condition of applying the water-soluble fertilizer without using any pesticide, the cucumber is planted without causing excessive plant diseases and insect pests all the time for two years.
