Abstract

The invention discloses a cabbage special use slow release fertilizer using biomass carbon granules as matrixes and a preparation method of the slow release fertilizer. The carbon granules prepared by agricultural waste biomass of corncobs, peanut shells, rice hulls, edible mushroom matrixes and the like are used as matrix materials, and by means of multiple micropores and high adsorption capacity of the carbon granules, the carbon granules are composite with nitrogen, phosphori, potassium and other nutrient elements which are required for growth and development of cabbage to prepare the granular biomass carbon matrix cabbage special use slow release fertilizer. According to the cabbage special use slow release fertilizer using the biomass carbon granules as the matrixes and the preparation method of the slow release fertilizer, the biomass carbon granules are black biomass carbon granules which are formed by incomplete combustion of the agricultural waste biomass under a low-oxygen condition so that the biomass carbon granules have a plurality of characteristics which are similar to those of soil humus and are high in capabilities of absorbing and keeping nutrients and water, the biomass carbon granules are capable of stimulating crop growth and good in slow release performances of the nitrogen, the phosphori and the potassium, and the prepared slow release fertilizer can effectively provide nutrients required in the whole growth period of the cabbage by one-time application and has the advantages of being efficient, environment-friendly, capable of increasing soil fertility and improving soil structures and beneficial to large-scale popularization and application in production of the cabbage.

Description

[0001] technical field

[0002] The invention belongs to the technical field of agricultural fertilizer production, in particular to a special slow-release fertilizer for cabbage with biomass granular carbon as a matrix and a preparation method thereof. Background technique

[0003] In cabbage production, reasonable fertilization is an important measure to ensure yield and quality. Cabbage, with leaf bulbs as its product, is the most sensitive to nitrogen requirements. Sufficient nitrogen supply will increase the chlorophyll content in the outer leaves, increase the production of carbohydrates, and also promote the growth of leaf bulbs and increase yield. Cabbage needs more nitrogen in the early growth stage, that is, the seedling stage and the rosette stage. The absorption of nitrogen reaches a peak in the rosette stage, and at the same time, it begins to absorb more phosphorus and potassium. During the leaf bulb formation period, the absorption of potassium and phosphoru...

Embodiment 1

[0078] Embodiment 1: The preparation technology of the slow-release fertilizer special for cabbage with biomass granular carbon as substrate

[0079] Follow the steps below to mix by weight ratio or weight percentage:

[0080] (1) Take large-grain urea with a nitrogen (N) content of 46%, and 80-mesh biomass granular carbon particles, mix them in a ratio of 70.0% and 30.0%, and use a disc granulator with a heating function (fertilizer Commonly used machinery in the preparation process) for coating to make an elemental slow-release nitrogen fertilizer with a nitrogen (N) content of 32.20%.

[0081] (2) Take diammonium phosphate powder with 18% nitrogen (N) content and 46% available phosphorus (P2O5) content, 80-mesh biomass granular carbon particles and binder, according to 73.7%, 20.3% Mix with 6.0% ratio, carry out pressure granulation with KP-300 type organic fertilizer granulator, make nitrogen (N) amount 13.27%, contain available phosphorus (P2O5) amount and be 33.90% ...
