Liquid fertilizer and preparation method thereof

Abstract

The invention relates to a liquid fertilizer and a preparation method thereof. The liquid fertilizer is composed of an inorganic nutrient substance, an organic nutrient substance and water, and is characterized by containing metronidazole. The liquid fertilizer and the preparation method thereof have the advantages that the liquid fertilizer can be prevented from swelling out of a bottle, the fertilizer loss is reduced, the quality of the fertilizer is stable, and the utilization rate of the fertilizer in soil is also increased.

Description

technical field [0001] The invention relates to a liquid fertilizer and a preparation method thereof. Background technique [0002] Water Soluble Fertilizer (Water Soluble Fertilizer, referred to as WSF ), is a multi-component compound fertilizer that can be completely soluble in water, it can be quickly dissolved in water, more easily absorbed by crops, and its absorption Utilization Relatively high, more critical is that it can be applied to spray drip irrigation and other facility agriculture, to achieve Water and fertilizer integration , to achieve the efficiency of saving water, fertilizer and labor. As a kind of water-soluble fertilizer, liquid fertilizer is more convenient and quick to use than powder fertilizer. In countries where drip irrigation technology and automatic fertilization are popular, liquid fertilizer has been widely used. In the United States, liquid fertilizer accounts for 38% of all fertilizers. , Israel's fields are almost all liquid fertiliz...

AI Technical Summary

Problems solved by technology

[0003] However, liquid fertilizers are usually stored in airtight containers because of their good fluidity. During the storage process, there are usually problems of bottle swelling and suction. At present, the solution to the problem of suction bottles is mainly to use cooling methods to make the gaseous water The vapor is cooled to a liquid state to prevent the gas from cooling after packaging, and the volume decreases to cause bottle suction; when solving the problem of bottle expansion, the method of heating and cooling and adding a defoamer is usually used to drive out the air in the liquid. This method is indeed It can prevent the phenomenon of bottle swelling in a short time, but with the extension of storage time, there will still be bottle swelling, and sometimes there will be a small amount of precipitation at the bottom of the container, which seriously affects the quality of the product

[0004] Due to unreasonable fertilization and management, there are problems in the soil used for farming, such as acidification and compaction. The demand for fertilizers in the soil is increasing, which also leads to more and more fertilization and lower utilization rates. , the task of zero growth in fertilizer agriculture faces challenges

[0005] At present, there is no method that can solve the phenomenon of bottle expansion caused by long-term storage of liquid fertilizers, nor does it solve the problem of sedimentation caused by long-term storage of liquid fertilizers, and there is no liquid fertilizer that can improve the utilization rate of fertilizers by applying it to acidified and compacted soil.
