Preparation method of liquid fertilizer suitable for water culture

Abstract

The invention discloses a preparation method of a liquid fertilizer suitable for water culture. The fertilizer comprises the following raw materials in parts by weight: 50-65 parts of fertilizer, 5-10parts of potassium nitrate, 5-10 parts of ammonium nitrate, 5-10 parts of monopotassium phosphate, 10-15 parts of ammonium phosphate, 10-15 parts of calcium nitrate, 80-100 parts of water, 3-5 partsof alum, 5-10 parts of an organic activator, 2-5 parts of an acid-base regulator, 2-5 parts of bactericide, 7-15 parts of alginate aqueous solution, 3-6 parts of chitin, 8-13 parts of amino acids and5-12 parts of microbiotics. According to the preparation method of the liquid fertilizer suitable for water culture, the liquid fertilizer suitable for water culture is obtained through simple operation steps of the simple preparation method, balanced supply of oxygen and nutrients in a nutrient solution in the growth process of crops can be well achieved, rotting of crop roots can be effectivelyinhibited, healthy growth of the crops is effectively promoted, and the yield of the crops is increased. Various growth elements and nutrients are provided for crops, and the cost of water culture crops is reduced.

Description

technical field [0001] The invention relates to the technical field of hydroponic fertilizer preparation, in particular to a method for preparing liquid fertilizer suitable for hydroponic cultivation. Background technique [0002] Soilless cultivation is a crop cultivation technique that does not use natural soil as a substrate. It is to cultivate crops directly in a nutrient solution in a certain device, or to cultivate crops on a cultivation bed filled with inactive solid substrates and nutrient solutions, because during the cultivation process , does not use traditional soil as a substrate, so it is called soilless cultivation. Hydroponics is a type of soilless cultivation in which crops are grown in a nutrient solution. [0003] In the existing hydroponic culture process, most of the crops are only supplied with nutrients through nutrient solution. This cultivation method will not only make the hydroponic crops prone to rotten roots, smelly and breed mosquitoes, but als...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a liquid fertilizer preparation method suitable for hydroponics, which solves the problem that most of the existing hydroponic processes only supply nutrients to crops through nutrient solution. This cultivation method not only It will make the hydroponic crops prone to rotten roots, smelly, and breed mosquitoes. At the same time, due to insufficient indoor light, the photosynthetic reaction of the crops is not complete, and the nutrient elements provided by the nutrient solution are relatively simple, resulting in slow growth of the crops, resulting in hydroponic The problem of higher crop costs
