Abstract

The present invention discloses one series of all-component high concentration water soluble composite fertilizers containing macro elements and trace elements essential for crops and its production process. The composite fertilizers are produced through recipe design, addition of Ca, Mg and other elements, addition of chelated trace elements, penetrant, nitrification inhibitor and other effective components. The composite fertilizers are high quality chemical fertilizers with raised nutrient contents, long acting period, capacity of promoting the absorption of crop, low production cost, capacity of improving soil structure and natural environment, and other advantages.

Description

technical field [0001] The invention relates to a series of compound fertilizers used in agriculture and forestry, in particular to a full-element high-concentration water-soluble long-acting compound fertilizer that can be applied to various crops and garden flowers. Background technique [0002] Fertilizer, as the food that supplies the nutrients needed by plants, has become an important basis for the development of modern agriculture. At present, ternary compound granular fertilizers based on N, P, and K have become the mainstream, and some fertilizers are also added with trace elements or multiple functional elements. Compared with ordinary simple fertilizers, this kind of fertilizer has improved fertilizer efficiency due to its comprehensive nutrition. However, existing compound fertilizers cannot be effectively absorbed by crops because they contain insoluble components and easily form antagonism between trace elements; A series of side reactions occur in the soil, r...
