Abstract

The invention discloses an organic-inorganic instantly dissolved slow controlled release fertilizer. The fertilizer comprises nutrients, organic matters and a mineral sodium base, wherein the nutrients are nitrogen, phosphorus and potassium; the effective contents of nitrogen, phosphorus and potassium are respectively computed according to N, P2O5 and K2O; in the organic-inorganic instantly dissolved slow controlled release fertilizer, the total weight percent of N, P2O5 and K2O is 20-40%, the weight percent of the organic matter materials is 15-40% and the weight percent of the mineral sodium base is 4-15%. The fertilizer has the advantages of strong pertinence, control of dissolution time, prevention of nutrient loss, capability of releasing according to the nutrient requirements of different crops and plants, and the like; meanwhile, the fertilizer can be used for maintaining virtuous cycle of soil nutrients, preventing soil hardening and improving the natural environment and is an ecological fertilizer capable of being applied for a long term.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic-inorganic instant slow-release and controlled fertilizer. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrient elements for plants, improves soil properties, and increases soil fertility. One of the material basis of agricultural production. The application of existing fertilizers often takes a long time to dissolve fertilizers, resulting in low fertilizer efficiency and loss of nutrients; and lack of pertinence, it cannot meet the different nutrients required by different crops or plants during the growth process and their ability to absorb nutrients. Contents of the invention [0003] The invention provides an organic-inorganic instant slow-release and controlled fertilizer. The purpose is to improve the fertilizer efficiency for plants, and the dosage can be adjusted to control the dissolution time of the fertilizer. [0004...
