Compound liquid fertilizer

Abstract

The invention discloses compound liquid fertilizer. The compound liquid fertilizer is prepared from the following raw materials in parts by mass: 10 to 65 parts of phosphorus fertilizer, 10 to 60 parts of calcium fertilizer, 12 to 60 parts of nitrogen fertilizer, 1 to 10 parts of magnesium fertilizer, 1 to 5 parts of potassium fertilizer, 50 to 200 parts of slow-release fertilizer, 5 to 10 parts of diammonium phosphate, 1 to 5 parts of an emulsifier, 2 to 5 parts of manganese sulfate, 0.8 to 5 parts of a co-solvent, 1 to 5 parts of a stabilizer, 70 to 130 parts of clean water and 3 to 8 partsof zinc sulfate. The compound liquid fertilizer disclosed by the invention has abundant nutrients and reasonable match; efficient utilization of the slow-release fertilizer is ensured and the compoundliquid fertilizer is more suitable for large-area fertilization; the compound liquid fertilizer can meet nutrients needed by the growth of crops and wastes of the fertilizer are reduced; the yield and quality of the farm crops are improved, the economic benefits are improved and the compound liquid fertilizer is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a compound liquid fertilizer. Background technique [0002] With the improvement of people's living standards, residents' demand for safe, hygienic and pollution-free organic and green food continues to increase. The majority of farmers urgently need to use organic fertilizers to improve the market competitiveness of agricultural products. At present, ordinary plant fertilizers are not easily absorbed by the soil and plants, and the effect is average. Most of the existing slow-release fertilizers are solid fertilizers, but the dissolution of solid fertilizers requires a lot of water. Sometimes due to lack of water and other reasons, the dissolution time of solid fertilizer chemical fertilizers is too long, which will affect the growth and development of crops. Liquid compound fertilizers have advantages over solid compound fertilizers in mechanical fertilization because their...
