The invention provides a slow-release water-holding fertilizer which comprises the following raw materials in parts by weight: 25-36 parts of ammonium nitrate, 21-29 parts of dicyandiamide, 13-18 parts of silica sol, 8-12 parts of urea, 5-8 parts of chitosan, 4-7 parts of kieselguhr, 2-5 parts of talcum powder, 1-4 parts of multi-vitamins and 0.5-2 parts of microelement. The slow-release water-holding fertilizer provided by the invention is rich in nutrients, such as nitrogen, phosphorus and potassium, and can be effectively absorbed by the plants; the ingredients are natural and harmless; thenutrients thereof have a synergistic effect of effectively supplementing plant nutrition; the slow-release effect is achieved through silica sol, chitosan and talcum powder; the fertilizer efficiencyis long-lasting; the water-holding effect is excellent; the slow-release water-holding fertilizer is safe and environment-friendly.
Description
technical field [0001] The invention relates to the technical field of horticultural fertilizers, in particular to a slow-release water-retaining fertilizer. technical background [0002] Fertilizer is a kind of substance that provides one or more essential mineral elements for plants, improves soil properties and improves soil fertility level, and is one of the material basis of agricultural production. At present, the compound fertilizers produced in our country are mainly composed of chemical fertilizers such as nitrogen, phosphorus, and potassium. The disadvantage is that after long-term use, it will not only aggravate the pests and diseases of crops, but also cause weeds to grow and cause serious environmental pollution. , make the soil ecological imbalance of cultivated crops, cause soil compaction and other phenomena, form a vicious cycle of agriculture, and restrict the sustainable development of my country's modern agricultural industry. [0003] Horticultural plant...
