Abstract

The invention provides a new-type slow-release fertilizer. The new-type slow-release fertilizer comprises the following raw materials in parts by weight: 22-35 parts of a phosphatic fertilizer, 18-26parts of a potassic fertilizer, 14-19 parts of silica sol, 7-10 parts of calcium lignosulphonate, 3-7 parts of chitosan, 2-5 parts of kieselguhr, 2-4 parts of talcum powder, and 1-3 parts of borax, and 0.5-2 parts of microelements. The slow-release fertilizer contains abundant nutrition raw materials of nitrogen, phosphorus, potassium and the like, can be absorbed by plants well, and is natural and harmless in composition. The slow-release fertilizer is capable of most efficiently replenishing plant nutrition through cooperation of nutrients, and achieving the slow-release effect through the silica sol, the chitosan and the talcum powder, lasting in fertilizer efficiency, good in water retention effect, safe and environmental.

Description

technical field [0001] The invention relates to the technical field of horticultural fertilizers, in particular to a novel slow-release 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 plants, like ot...
