High-phosphorus, high-zinc and high-magnesium liquid compound fertilizer as well as preparation method and application method thereof

Abstract

The invention provides high-phosphorus, high-zinc and high-magnesium liquid compound fertilizer. The high-phosphorus, high-zinc and high-magnesium liquid compound fertilizer is prepared from the following raw material components in parts by weight: 3-15 parts of zinc fertilizer, 4-16 parts of magnesium fertilizer, 16-75 parts of phosphorus fertilizer, 1-15 parts of urea, 0.5-8 parts of potassium fertilizer, 0.5-4 parts of cosolvent, 0.5-4 parts of stabilizer and 10-40 parts of water. The invention also provides a preparation method and an application method of the high-phosphorus, high-zinc and high-magnesium liquid compound fertilizer. The high-phosphorus, high-zinc and high-magnesium liquid compound fertilizer has the advantages that the total nutrient content is high, physical and chemical shapes are stable, phosphorus, zinc and magnesium are stably dissolved in liquid at the same time, phenomena such as crystallization, sedimentation, layering and the like are not caused under high temperature, low temperature and normal temperature conditions, liquidity is good, nutrients are highly enriched, the high-phosphorus, high-zinc and high-magnesium liquid compound fertilizer is applicable to automatic fertilization operation in a relatively large area, fertilization efficiency can be obviously improved, foliar application and drenching can be realized, and the high-phosphorus, high-zinc and high-magnesium liquid compound fertilizer also can be applied to a spray irrigation and drop irrigation system, is easy to use, is time-saving, labour-saving and fertilizer-saving and is quick in fertilizer effect.

Description

technical field [0001] The technical field of fertilizer production of the present invention specifically relates to a large-scale and medium-trace element fertilizer applied to crops, especially a high-phosphorus, high-zinc, and high-magnesium liquid compound fertilizer and its preparation method and use method. Background technique [0002] Phosphorus is one of the macronutrient elements necessary for crop growth and development. It is an indispensable element for the formation of nuclear protein and lecithin. Phosphorus can accelerate cell division, accelerate root and shoot growth, promote flower bud differentiation, early maturity, and improve fruit quality. For example, it plays an important role in the respiration, photosynthesis, sugar decomposition and transportation of crops. Phosphorus can promote seed germination, help flower bud differentiation, promote good flowering, and promote early maturation and fruiting; it can also promote root development, making root...

AI Technical Summary

Problems solved by technology

In agricultural production, the combined application of phosphorus fertilizer, zinc fertilizer and magnesium fertilizer is inevitable, but when phosphorus fertilizer is applied to the soil, it is easy to form insoluble zinc phosphate and magnesium phosphate salts with zinc ions and magnesium ions, thus affecting the production of zinc and magnesium. the effectiveness of
