Problems solved by technology

[0003] In China, the field of liquid fertilizers has just started, and the technology is rough. Simply mixing and dissolving raw materials containing nitrogen, phosphorus, and potassium directly in water makes domestic liquid fertilizers pay too much attention to the supplementation of large amounts of nitrogen, phosphorus, and potassium, while ignoring the effects on crops. The role of the root system
Moreover, simple fertilizers such as nitrogen, phosphorus, and potassium have single nutritional components, and improper use can easily cause problems such as soil compaction.
Organic fertilizers have a complete range of nutrients, but the nutrient content is low, and most of them are in an organic state, and the release of nutrients is slow

Abstract

The invention discloses a liquid fertilizer for promoting plant root system growth and a preparation method thereof. Active ingredients of the liquid fertilizer comprise 0.5-1.0g / L of Ca(NO3)2, 0.1-0.2g / L of KH2PO4, 5-10g / L of biomedical carbon, 3-5g / L of saccharosesugarcane; 0.02-0.05% of alcohol is added in volume fraction, and Ca(NO3)2, KH2PO4, biomedical carbon, saccharosesugarcane and water are mixed to prepare mother liquor; and the obtained mother liquor is mixed in proportion to obtain a liquid fertilizer. The liquid fertilizer can effectively improve the soil structure, enhances fertilizer effect, promotes growth, and promotes soil chemical activity and bio-activity to be improved. According to the test, the plant root system activity is improved by 10%-24% through the liquid fertilizer, and dry weight of roots is increased by 7%-15%, so that the technical effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of plant fertilizers, and relates to a liquid fertilizer for promoting the growth of plant roots and a preparation method thereof. Background technique [0002] Liquid fertilizer is nitrogen, phosphorus, potassium, trace elements and other synergists dissolved in water as solutes. Due to the advantages of instant dissolution and uniformity, it is the preferred fertilizer for fertilization by drip irrigation equipment; due to its ready-to-use, no need to stir and dissolve, it is very suitable for automatic fertilization. In countries where irrigation technology and automated fertilization are popular, liquid fertilizers are widely used. Liquid fertilizers in the United States account for about 38% of all fertilizers, and Israel's field plans use liquid fertilizers. Australia, Europe and other countries are countries that use liquid fertilizers in large quantities. [0003] In China, the field of liquid fert...
