Organic soluble fertilizer capable of protecting root system and modifying soil and preparation method thereof

Abstract

The invention discloses an organic soluble fertilizer capable of protecting a root system and modifying soil and a preparation method thereof. The organic soluble fertilizer comprises the following components by content: living bacteria larger than or equal to 5 billion per ml, amino acid larger than or equal to 100g / L, humic acid of 40-150 g / L, and calcium and magnesium secondary elements larger than or equal to 30g / L. The method comprises the following steps: performing vacuum evaporation and concentration for humic acid solution containing living bacteria, free amino acid solution and mixture of calcium and magnesium secondary elements to an extent that the living bacteria is larger than or equal to 5 billion per ml, the amino acid is larger than or equal to 100g / L, the humic acid is of 40-150 g / L, and calcium and the magnesium secondary elements are larger than or equal to 30g / L, wherein the evaporating temperature is lower than 50 DEG C. The fertilizer can be directly applied, is convenient and labor-saving, can be easily absorbed by plants in a form of liquid, and has the advantages of improving soil texture and ability of crops resisting disease and insect pests, being capable of protecting plant root system and stimulating plant yield, and being quick in manurial effect, balance in nutrition, and simple in application.

Description

technical field [0001] The invention relates to an organic water-soluble fertilizer for protecting root system and improving soil, in particular to a preparation method of organic water-soluble fertilizer for protecting root system and improving soil. Background technique [0002] Chemical fertilizers are referred to as chemical fertilizers, including inorganic fertilizers and organic fertilizers; in terms of form, they can be divided into solid fertilizers and liquid fertilizers. Chemical fertilizers play a significant role in increasing crop yields and are indispensable production factors in modern agriculture. People's long-term use of inorganic fertilizers can easily lead to a decrease in soil fertility, which not only destroys the acid-base balance of the soil, but also causes problems such as soil compaction and salinization; the nitrate content in agricultural products exceeds the standard and the quality deteriorates. The use of organic fertilizers mainly replaces i...

Problems solved by technology

Long-term use of inorganic chemical fertilizers by people can easily lead to a decrease in soil fertility, which not only destroys the acid-base balance of the soil, but also causes problems such as soil compaction and salinization; the nitrate content in agricultural products exceeds the standard and the quality deteriorates

The use of organic fertilizers mainly replaces inorganic fertilizers with traditional farmyard manures to produce pollution-free agricultural products. Although it has the advantages of improving soil fertility and crop quality, the disadvantages of organic fertilizers are slow fertilizer efficiency and little increase in crop yields. If you want to increase yields It is necessary to increase the amount of organic fertilizer application in a large amount, and due to the limited resources of organic fertilizer, it is far from meeting the needs of modern agricultural development, especially for melons, fruits and vegetables.

Although some existing single fertilizers such as humic acid, amino acid and microbial fertilizer contain beneficial ingredients for plant growth, especially each fertilizer contains plant growth regulators, which need to be combined by farmers themselves during use, which is difficult to master The amount of different fertilizers is very prone to various adverse phenomena such as crazy growth of plant leaves and deformed fruits, which seriously affects the quality of crops
