Description

Nutritional balanced fertilizer based on trace elements and its processing method

Technical field

The invention relates to a soil and crop nutrient agent and its production process, in particular to a nutritional balance fertilizer based on trace elements and its production process.

Background technique

There are currently a wide variety of organic fertilizers (or various types of fertilizers) on the market, and the various elements are mainly chemical synthetic substances. The long-term use of chemical fertilizers and pesticides has caused varying degrees of acidification and hardening of the soil, which has also led to a decrease in soil fertility. With high barrenness, the ecological function of the soil deteriorates and the relationship between soil biological flora is destroyed. In this way, not only the quality of crops cannot be guaranteed, but also the soil will be abandoned.

In the existing technology, mineral fertilizers are used to solve the above problems. However, the component materials are not distributed reasonably, and the component composition is relatively single. The pH value of the proportioned product is single, and it cannot adapt to diverse soil usage conditions and crop growth. Due to the diversified nutritional needs, the gain of soil beneficial bacteria and soil active substances is limited, making it difficult to achieve soil nutritional balance, and the improvement of crop quality is also limited. .

Contents of the invention

The object of the present invention is to provide a trace-based method based on the shortcomings of the existing technology that can effectively promote the reproduction of beneficial soil bacteria, regulate the relationship between soil microbial flora, enhance the accumulation of soil active substances, regulate soil nutritional balance, and improve the quality of crops. Elemental nutritional balance fertilizer and its processing method.

The nutritionally balanced fertilizer based on trace elements of the present invention is achieved through the following approaches:

The main point of nutritionally balanced fertilizer based on trace elements is that it includes the following components:

The ore powder extract, softened water and plant fermentation liquid prepared according to the pH requirements, the ore powder extract is an acidic ore powder, alkaline that is mixed, stirred and moderately heated according to the pH requirements. Ore powder, softened water and a mixed liquid after solid-liquid separation. The alkaline ore powder includes perlite, limestone and shell powder. The acidic ore powder obtained by acid hydrolysis includes vermiculite and medical stone.

The main component of the alkaline ore powder is calcification, of which 95% of the shell powder is calcium carbonate, chitin, and a small amount of amino acids and polysaccharides. The alkaline ore powder can regulate soil hardening, prevent crops from lodging, and control fertilizer efficiency. It has antibacterial and bacteriostatic effects. The acidic ore powder is rich in magnesium, sulfur, copper, iron, zinc, manganese, potassium, selenium, silicon and other medium and trace elements. In addition, after acidification treatment, some sulfur elements will remain in the liquid, which can Fully meet the various nutrients necessary for the normal growth and development of different crops, thereby enhancing the disease resistance and stress resistance of crops.

Trace elements can promote photosynthesis, increase the activity of oxidative enzymes in plants, and increase nitrogen metabolism.

Plant fermentation liquid usually refers to some natural fresh vegetables, fruits, brown rice, mushrooms, medicinal and edible traditional Chinese medicine and other plants that are fermented by one or more probiotics to produce rich enzymes, vitamins, minerals, amino acids, A liquid obtained by filtering a mixture of various organic acids, polysaccharides and other nutrients to remove impurities.

The organic matter in plant fermentation broth can promote crop growth and development and is the main source of soil nutrients; the beneficial bacteria include yeast, lactic acid bacteria, photosynthetic bacteria, and actinomycetes. Yeast can loosen the soil, increase soil water retention, and promote crop root growth; lactic acid bacteria can decompose lignin and cellulose that are not easily decomposed at room temperature, and promote the fermentation and decomposition of organic matter; photosynthetic bacteria can quickly activate plant cell activity and promote root growth. Improve photosynthesis; actinomycetes have a high bactericidal effect and have a more obvious effect on soil diseases; humic acid has a certain cultivation function for biological bacteria and can automatically adjust the growth mechanism of biological bacteria and promote the growth of biological bacteria.
