Problems solved by technology

2. Poor environmental protection, resulting in serious soil compaction
Excessive use of chemical fertilizers will deteriorate the physical and chemical properties of the soil, block the soil voids, destroy the soil aggregate structure, and cause the imbalance of soil nutrients, compaction, pollution and decline in fertility
At the same time, excessive application of chemical fertilizers can also lead to groundwater pollution and air pollution, which is also a thr...

Abstract

The invention belongs to the field of agricultural fertilizers, and particularly relates to a multi-elementary fulvic acid fluid water-soluble fertilizer and a preparation method thereof. The fertilizer is easy to be absorbed by crops, fast in absorbing speed, and high in efficiency. The multi-elementary fulvic acid fluid water-soluble fertilizer is prepared from, by weight, not less than 260-508g/L of massive elements nitrogen+ phosphorus+ potassium, not less than 10-15 g/L of trace elements iron, zinc, copper and boron, not less than 2g/L of cobalt, and not less than 60-90g/L of humic acid. The multi-elementary fulvic acid fluid water-soluble fertilizer is prepared by a certain preparation method.

Description

[0001] 1. Technical field [0002] The invention belongs to the field of agricultural fertilizers, in particular to a multi-element fulvic acid liquid water-soluble fertilizer and a preparation method thereof. [0003] 2. Background technology: [0004] With the rapid development of the chemical industry, the production and application of various fertilizers have been increasing, which has played an important role in promoting the development of agricultural production. However, with the continuous increase in the amount of chemical fertilizer application, the disadvantages of its application are also increasingly prominent, mainly in the following aspects: 1. The cost of fertilization increases due to high input and low output. At present, the utilization rate of nitrogen fertilizer in my country's chemical fertilizer field is only 15-40%, the utilization rate of phosphorus fertilizer is only 10-20%, and the utilization rate of potassium fertilizer is only 20-25%. 2. It is po...
