Organic/inorganic compound fertilizer for asparagus and preparation method thereof

Abstract

The invention relates to an organic / inorganic compound fertilizer for asparagus, which is composed of the following raw materials in parts by weight: 45-90 parts of sheep manure, 5-15 parts of cake fertilizer, 1-10 parts of peat, 4-12 parts of ammonium bicarbonate, 1-10 parts of calcium superphosphate, 1-10 parts of bacterial fertilizer and 0.5-4 parts of minor element fertilizer. The preparation method comprises the following steps: (1) proportionally and uniformly mixing the sheep manure, cake fertilizer and peat, adding the bacterial fertilizer, covering a plastic film, and carrying out pile fermentation for 48-72 hours; (2) after the fermentation finishes, lifting the pile once, and lifting the pile every other 24 hours once or twice, thereby completing incipient fermentation; (3) after the incipient fermentation product is cooled to 25 DEG C below, adding the ammonium bicarbonate, calcium superphosphate and minor element fertilizer, uniformly mixing, carrying out refermentation, and lifting the pile every other 15-30 minutes two or three times; and (4) airing for use. The fertilizer has the advantages of high fertility, long fertilizer effect, comprehensive nutrients and high utilization ratio, and can protect the soil fertility.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an asparagus organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] Asparagus, also known as Shi Diaobo, is one of the top ten famous dishes in the world. Enjoying the reputation of "King of Vegetables" in the international market, asparagus is rich in various amino acids, proteins, vitamins and trace elements such as selenium and molybdenum, which can regulate the body's metabolism and improve the body's immunity. Asparagus is a perennial crop, which has high requirements on soil site conditions and nutrient requirements. On fertile soil with deep, loose soil and rich in organic matter, the economic life of asparagus can reach 14-18 years. [0003] At present, the production of asparagus is mainly based on chemical fertilizers. Long-term operation often leads to soil degradation, aggravation of asparagus pests and diseases, ...
