Liquid compound fertilizer for swelling fruit period and preparation method thereof

Abstract

The invention discloses a liquid compound fertilizer for a swelling fruit period, which belongs to the technical field of fertilizers, and comprises raw materials in every 1L: nitrogenous fertilizer calculated by nitrogen (N) 170-180g, phosphatic fertilizers calculated by phosphorus pentoxide (P2O5) 80-100g, potash fertilizers calculated by potassium (K) 250-260g, microelements 2.475-3.425g, xanthan gum 1.4-4.2g, sodium pyrophosphate 5.6-8.4g and potassium humate 30-40g, and the other is water. A method for preparing the liquid compound fertilizer for the swelling fruit period comprises steps: the potash fertilizers, the xanthan gum and the sodium pyrophosphate are added into the water to mix, then are added with the nitrogenous fertilizer, the phosphatic fertilizers c and the potassium humate to stir and dissolve, then are added with the microelements to stir and dissolve, are metered volume to 1L through the water, and are uniformly stirred, thereby obtaining the liquid compound fertilizer for the swelling fruit period by filling after grinding. The liquid compound fertilizer for the swelling fruit period is a suspension type liquid compound fertilizer with balanced, steady and uniform in nutrition, reduces leaching loss in soil, improves utilization rate in the soil, and is excellent in increase yield of crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a liquid compound fertilizer for fruit expansion stage 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...

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
