Liquid compound fertilizer for seedling lifting and preparing method of liquid compound fertilizer

Abstract

The invention discloses liquid compound fertilizer for seedling lifting and belongs to the technical field of fertilizer. Each 1 L of liquid compound fertilizer is prepared from, 103.8-112.4 g of nitrogenous fertilizer in N, 273.8-281.2 g of phosphatic fertilizer in P2O5, 106.99-119.59 g of potassium fertilizer in K2O, 2.865-4.135 g of microelements and the balance water. A corresponding preparing method of the liquid compound fertilizer comprises the steps that the nitrogenous fertilizer, the potassium fertilizer and the phosphatic fertilizer are added into water, stirred and dissolved, then the microelements are added, the volume is metered to 1 L with water, the mixture is evenly stirred, ground and poured, and the liquid compound fertilizer is obtained. The prepared suspension type liquid compound fertilizer is good in solubility, the use amount of the fertilizer is small, the leaching loss of the fertilizer in soil is reduced, the utilization rate of the fertilizer in the soil is increased, the yield-increasing effect of crops is good, the preparing method of the liquid compound fertilizer is simple, low in energy consumption and easy to operate, the production cost is reduced, and the production process is free of pollution, safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a liquid compound fertilizer for raising seedlings and a preparation method thereof. Background technique [0002] Fertilizer is an essential material support for promoting plant growth and increasing crop production, and it is also one of the important conditions for the development of agricultural production. 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 add...

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

[0003] Compound fertilizer refers to chemical fertilizers containing any two or more of the crop nutrient elements nitrogen, phosphorus, and potassium made by chemical methods or (and) mixed methods. The commonly used chemical methods in the prior art are: mixing the required raw materials Stir evenly in proportion, and get the finished product through crushing, agglomeration, granulation, screening, drying, cooling, coating, and packaging. The fertilizer made by this production process is granule, which has complex process, large equipment investment, and high production cost. Insufficient high
