Problems solved by technology

China is one of the countries that consume a lot of agricultural fertilizers in the world. At present, the common fertilizers on the market are high-concentration solid fertilizers with relatively single components, such as urea and nitrophosphate fertilizers. These fertilizers can only provide a large amount of nitrogen, phosphorus, and potassium. Nutrient elements, almost do not contain medium elements and trace elements, so that the crops have low lodging resistance, resistance to diseases and insect pests, and crops are easy to reduce production. In addition, fertilizer leaching is relatively serious, and the absorption and utilization rate of fertilizers is reduced. In recent years, due to long-term use of "Precise" nitrogen, phosphorus and potassium fertilizers cause soil acidification, compaction and deep soil pollution, and the various grains, vegetables and fruits produced cannot meet the requirements of green and organic food, bringing potential harm to people's health; The use of a large number of various fertilizers also pollutes groundwater, rivers and lakes, destroys the ecological balance, and causes a vicious circle of environmental pollution. How to balance fertilization, reduce the amount of chemical fertilizers, and protect the environment is an urgent problem to be solved in agricultural production
[0004] The demand for organic liquid fertilizers in my country is very large, but the research on liquid fertilizers in my country has been in a relatively backward state, and there are very few compound fertilizers in liquid form. Although some manufacturers can produce liquid fertilizers, these liquid fertilizers are all low in nutrient content. Variety, also increases the transportation cost
In the production process of liquid fertilizer, it is necessary to use stirring equipment to stir the raw materials of liquid fertilizer, and in the stirring process, due to the effect of stirring, a large number of air bubbles will be generated. In the prior art, adding defoamer or stirring After the completion of the defoaming operation, because most of the defoaming agents have a certain degree of toxicity, they cannot meet the use requirements of the fertilizer, and the defoaming operation after the stirring is completed will greatly affect the production efficiency of the fertilizer

Abstract

The invention discloses a liquid compound fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizers. The liquid compound fertilizer comprises livestockmanure, plant straw, a liquid nitrogen fertilizer, a liquid phosphate fertilizer, a liquid potash fertilizer, trace elements, potassium phytate, a suspending agent, a plant growth regulator, water andother components, and is a suspension type liquid compound fertilizer which is balanced, stable and uniform in nutrition. According to the invention, the utilization rate of the fertilizer in soil isincreased; the liquid compound fertilizer is applied in the topdressing period of crops, the application amount is small, the single fruit weight of the crops is increased, the yield increasing effect of the crops is good, and storage and transportation are convenient; and meanwhile, the preparation method is simple, a special defoaming and stirring device is used for fully stirring and mixing the raw materials so as to prepare the fertilizer, foam can be automatically eliminated in the stirring process, defoaming is sufficient and complete, no redundant defoaming process or defoaming agent needs to be added, and the production efficiency of the liquid compound fertilizer is greatly improved.
