Abstract

The invention relates to the technical field of compound fertilizers, in particular to a special slow-release fertilizer for flowers. The special slow-release fertilizer comprises raw materials in parts by mass as follows: 20-40 parts of ammonium nitrate, 3-8 parts of manganese sulfate, 2-6 parts of zinc sulfate, 1-5 parts of ferric citrate, 5-10 parts of diammonium phosphate, 2-6 parts of magnesium sulfate, 2-6 parts of borax, 2-7 parts of ammonium molybdate, 2-8 parts of sodium alginate and 0.8-2.4 parts of potassium humate. Compared with commercially available ordinary fertilizers for the flowers, the special slow-release fertilizer for the flowers has the advantages that the highest peak of nutrient releasing of N, P and K is postponed by 5 days, the nutrient releasing amount of N, P and K is reduced by 125 mg/kg, 35 mg/kg and 80 mg/kg in 30 days respectively, so that the flower season of the potted flowering-ornamental flowers is prolonged by 7-12 days, leaves of the foliage-ornamental flowers are deep green, the slow-release fertilizer is safe, hygienic and free of odor and has a long-lasting effect in the use process, and the holding time lasts for 3-4 months.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special slow-release fertilizer for flowers. Background technique [0002] There are three main types of flower fertilizers: chemical fertilizers, organic fertilizers, and imported flower-specific fertilizers. In addition, there are flower compost produced from vegetable and flower residue waste, flower-specific fertilizers, and flower-specific slow-release fertilizers. Organic fertilizers are produced from human and livestock excrement as the main raw material. The processing efficiency is low, the nutrient content is low, and it will bring diseases and insect pests. Chemical fertilizers are fertilizers made from field crops as the main raw materials, such as urea, phosphorus and potassium compound fertilizers, etc., which have quick effects, short fertilizer effects, and are easy to compact the soil. The flower compost and flower special slow-release fertilizer ...
