Abstract

The invention discloses a controlled release fertilizer. The controlled release fertilizer is mainly prepared from, by weight, 44-50 parts of Pholiota nameko waste bran, 8-11 parts of expanded vermiculite powder, 1.4-2.0 parts of a water retaining agent, 8-12 parts of bentonite, 9-13 parts of rapeseed cakes, 8-12 parts of straws, 8-10 parts of bean curd residues, 10-16 parts of coated urea, 20-28 parts of urea, 6-10 parts of orange peel, 2-4 parts of a composite microbial agent and 1.0-1.4 parts of slaked lime powder. The Pholiota nameko waste bran is fully used in the invention, so pollution of Pholiota nameko waste bran abandoning to environment is reduced; and the controlled release fertilizer has the advantages of good water retention and fertilizer conservation properties, aloe growth promotion, output improvement, and great saving of manpower and material cost.

Description

technical field [0001] The invention relates to the field of slow-release fertilizers, in particular to a controlled-release fertilizer and a preparation method thereof. Background technique [0002] The growth and development of edible fungi all need sufficient carbon source, nitrogen source and a certain amount of inorganic salt and vitamin nutrition. Slider mushroom is a wood rot fungus, and its growth depends on mycelium absorbing mineral elements such as soluble nitrogen and calcium from the medium. Artificial cultivation of Pleurotus chinensis usually uses sawdust, straw, rice bran, wheat bran and other agricultural and sideline products rich in lignin, cellulose, hemicellulose and protein as the culture material for artificial cultivation. However, after the mushroom is cultivated, a large part of the waste fungus chaff cannot be effectively treated. For example, the direct application of the waste fungus chaff of Huazi mushroom to the field will cause a series of n...
