Water-soluble fertilizer capable of improving alkaline soil and preparation method of water-soluble fertilizer

Abstract

The invention discloses water-soluble fertilizer capable of improving alkaline soil. The formula of the water-soluble fertilizer comprises the following raw materials in parts by mass: 1000 to 1500 parts of dried pine needle, 1000 to 1300 parts of sodium alginate, 1000 to 1500 parts of vinegar dreg, 800 to 1200 parts of vermiculite, 1200 to 1800 parts of nano carbon, 35 to 50 parts of plant ash, 10 to 20 parts of humic acid raw powder, 50 to 80 parts of magnesium sulfate, 60 to 90 parts of a compound enzyme preparation and 30 to 60 parts of a compound bacterium agent. According to the water-soluble fertilizer disclosed by the invention, the dried pine needles are utilized; the dried pine needles contain a lot of proteins, crude fat, vitamin K, various types of mineral substances including calcium, phosphorus, iron and the like and a plurality of types of enzymes, so that nutrients of the soil can be remarkably improved; meanwhile, the water-soluble fertilizer also contains a lot of alpha-aminobutyric acid, threonine, glycine, alanine and the like and has an acidic property, so that the water-soluble fertilizer can be used for neutralizing the alkaline soil in a process of providing the nutrients.

Description

technical field [0001] The invention relates to a water-soluble fertilizer for improving alkaline soil and a preparation method thereof. Background technique [0002] Soil salinization has a relatively large damage to the physical and chemical properties of the soil, which is extremely unfavorable to the growth of many crops, and it is easy to cause the lack of seedlings or death of crops, thus hindering the development of agricultural economy. Due to the high salt content, low organic mass, and high pH in saline-alkali land, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. Bad, serious will cause plant wilting, poisoning and rotten root death. In addition, if the soil is too alkaline, it will affect the availability of nutrients such as phosphorus, iron, manganese, boron, and zinc in the soil, and will easily cause a large amount of nitrogen, phosphorus, and potassium major elements, as well as trace elements such as iro...

Problems solved by technology

In addition, if the soil is too alkaline, it will affect the availability of nutrients such as phosphorus, iron, manganese, boron, and zinc in the soil, and will easily cause a large amount of nitrogen, phosphorus, and potassium major elements, as well as trace elements such as iron, calcium, and boron.

[0003] At present, most of the commonly used fertilizers for improving alkaline soil contain very single ingredients. Long-term use will cause soil compaction, loss of nitrogen, phosphorus, and potassium in the soil, slow growth of crops, decline in resistance to diseases and insect pests, and reduced yield.
