Ecological nutritional compound fertilizer, and preparation method and application thereof

Abstract

The invention provides an ecological nutritional compound fertilizer which comprises the following raw materials by weight parts: 0.1-0.5 parts of dicyandiamide, 0.3-0.8 parts of hydroquinone, 10-30 parts of melocol, 10-30 parts of urea, 15-30 parts of ammonium polyphosphate, 10-40 parts of potassium polyphosphates, 0.1-0.5 parts of polypeptide, 0.1-7.5 parts of medium trace elements and 0.2-0.5 parts of plant probiotics. The compound fertilizer is especially suitable for the crops with long growth period; the compound fertilizer, which is applied for one time, can meet the requirement of the whole growth period of the crops; the use ratio of the fertilizer is high; the quality of agricultural products is increased; the dosage of pesticides is reduced; and the commodity value of the agricultural products is increased. After the compound fertilizer is applied, the soil hardening is reduced, the soil is fertile, the soil physical properties are improved, the growth of the crops is boosted, the water evaporation is reduced, the root growth is boosted, the drought resistance of the crops is enhanced, the output of crops is increased and the quality of the crops is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an ecological nutritional compound fertilizer and its preparation method and application. Background technique [0002] At present, ordinary fertilizers are mainly composed of inorganic nutrients such as nitrogen, phosphorus, and potassium. They do not contain medium and trace elements, and the nutrients are not comprehensive. They cannot meet the needs of crop growth, and they do not have controlled release. Insufficient, it is difficult to match the nutrient requirements of the crop growth cycle. Domestic controlled-release fertilizers are mainly produced by coating, which wraps a layer of inert substances on the surface of urea and compound fertilizers to delay the release of nutrients and improve nutrient utilization. However, there are still many problems, such as the relationship between nutrient release rate and crop nutrient Demand is difficu...

Problems solved by technology

[0002] At present, ordinary fertilizers are mainly composed of inorganic nutrients such as nitrogen, phosphorus, and potassium. They do not contain medium and trace elements, and the nutrients are not comprehensive. They cannot meet the needs of crop growth, and they do not have controlled release. Insufficient, difficult to match the nutrient requirements of the crop growth cycle

Domestic controlled-release fertilizers are mainly produced by coating, which wraps a layer of inert substances on the surface of urea and compound fertilizers to delay the release of nutrients and improve nutrient utilization. However, there are still many problems, such as the relationship between nutrient release rate and crop nutrient The demand is difficult to be consistent, the production control requirements are strict, the package is uneven, the package thickness is too large, it is difficult to release nutrients, the package thickness is small, the nutrient release cannot be controlled, the quality is unstable, and the cost of fertilization is high.
