Slow-released fertilizer for greening plants and preparation method of fertilizer

Abstract

The invention discloses a slow-released fertilizer for greening plants and a preparation method of the fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 60-80 parts of cow dung, 24-45 parts of fallen leaves and weeds, 15-20 parts of potato starchy residues, 10-15 parts of castor cakes, 5-10 parts of palm kernel meal, 14-18 parts of dried beancurd stick residues, 12-16 parts of peanut bran, 10-15 parts of sunflower seed cakes, 7-13 parts of soy residues, 10-15 parts of burnt sienna, 5-10 parts of furnace ash residues, 6-12 parts of red mud, 5-10 parts of shale ceramisite, 4-8 parts of chalk powder, 3-6 parts of tea pollen, 2-4 parts of magnesia, 15-20 parts of polyacrylic acid, 5-10 parts of hydroxyethyl cellulose, 1-2 parts of undecylenic alcohol ester, 3-6 parts of sodium lignosulphonate, 4-8 parts of polyvinyl alcohol, 15-20 parts of solid paraffin, 10-15 parts of asphalt, 5-10 parts of rosin and 20-30 parts of tung oil. The fertilizer is good in slow release performance and high in fertilizer efficiency, and has important economic, social and ecological benefits; nutrients needed for early growth of the greening plants can be provided, so that the greening plants grow well; the sufficient fertilizer can be provided for later-period growth of the greening plants, so that the 2-4-year nutrient requirements of greening nursery stocks are completely met, the fertilizer does not need to be applied for multiple times, the utilization rate of the fertilizer is increased, and the fertilizing cost is reduced.

Description

technical field [0001] The invention relates to a greening plant-releasing fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] In recent years, with the continuous deepening of reform and opening up and the continuous development of the economy, people's understanding of the function of greening in urban construction has gradually increased, the urban green area has increased significantly, and green maintenance has become the core work of landscaping. In urban greening work, fertilization management is one of the important measures of greening maintenance, and the most important thing about fertilization is fertilizer, which is the decisive factor to improve the quality of greening plants and ensure the healthy growth of greening plants. At present, the fertilizers used for greening plants in the market have poor slow-release performance, fast nutrient release, short fertilizer effect, need to be applie...
