Abstract

The invention discloses special slow-release fertilizer for citruses and a preparation method of the special slow-release fertilizer. The fertilizer is prepared from raw materials in parts by weight as follows: 40-60 parts of urea, 10-20 parts of calcium superphosphate, 10-20 parts of potassium chloride, 5-15 parts of oyster powder, 50-80 parts of citrus pomace, 30-50 parts of biogas residues, 20-40 parts of silkworm shit, 20-30 parts of water hyacinth powder, 3-6 parts of a microbial agent and 3-8 parts of a coating material. Organic-inorganic fertilizer and the coating material are combinedfor preparation of the slow-release fertilizer, the utilization rate of nutrient elements of the fertilizer can be increased, the slow release effect of the fertilizer is remarkable, the fertilizer cost is reduced, different demands of citruses for nutrients in different growth periods in the whole year can be met, the proportion of organic fertilizer to inorganic fertilizer can be set scientifically and reasonably, sufficient nutritional ingredients can be provided for growth of the citruses, and the production speed and yield of the citruses can be significantly increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a special slow-release long-acting fertilizer for citrus and a preparation method thereof. Background technique [0002] Citrus (Citrus reticulata Blanco) belongs to the Rutaceae plant, also known as citrus. my country is one of the important origins of citrus, with rich citrus resources and a wide variety of fine varieties, with a cultivation history of more than 4,000 years. After long-term cultivation and selection, citrus has become a precious fruit for human beings. More than 30 kinds of human health substances contained in citrus have been isolated, mainly including: flavonoids, monoterpenes, coumarins, carotenoids, propanols, acridones, glycerol glycolipids, etc. The citrus fruit is edible, and the citrus peel, citrus leaves, and citrus roots can be used as medicine, which has different functions such as reducing phlegm, relieving cough, soothing the liv...
