Problems solved by technology

With the continuous expansion of the pepper planting area, organic fertilizers can no longer meet the needs, and the repeated application of chemical fertilizers has the following shortcomings: First, it increases the labor intensity and labor costs of farmers; second, the root regeneration ability of peppers is not strong, and frequent digging Furrow fertilization will cut off a large number of roots and affect the absorption of nutrients
In the burning season, there have been many incidents where flights could not land and highways were forced to close due to the smog in the sky, which not only wasted a lot of precious resources, but also brought serious pollution to the environment.

Embodiment 1

[0078] Embodiment 1: The preparation process of the special slow-release fertilizer for capsicum with biomass granular carbon as the 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 64.4% and 35.6%, 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 29.62%.

[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 70.7%, 22.8% Mix with 6.5% ratio, carry out pressure granulation with KP-300 type organic fertilizer granulator, make nitrogen (N) amount 12.73%, contain available phosphorus (P2O5) amount and be 32.5...

Abstract

The invention discloses a special slow-release fertilizer taking biomass granular charcoal as a matrix for hot pepper and a preparation method for the same. The preparation method comprises the following steps of: taking the granular charcoal which is prepared from the agricultural waste biomasses of corncobs, peanut shells, rice hulls, edible fungi matrix and the like as a matrix material, compounding the matrix material with nitrogen, phosphorus, potassium and other nutrient elements which are necessary to the growth and development of hot pepper by virtue of the microporous property and the strong adsorption capacity of the matrix material, and then preparing the granular biomass charcoal-matrix special slow-release fertilizer for hot pepper. The biomass granular charcoal used in the preparation method disclosed by the invention is the black biomass granular charcoal granules formed by the agricultural waste biomasses after incomplete combustion in a low-oxygen condition, has various characteristics similar to the characteristics of soil humus, as well as is very strong in the capacities of adsorbing and keeping nutrients and water, capable of stimulating the growth of crops, and good in slow-release performance for nitrogen, phosphorus and potassium; and the slow-release fertilizer prepared from the biomass granular charcoal can effectively meet the need of hot pepper to nutrients in the whole growing period in case of being applied once, and has the characteristics of enhancing soil fertility, improving soil structure, being efficient and environment-friendly and the like, thus being beneficial to large-scale popularization and application in production for hot pepper.

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 capsicum with biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] The main root of pepper is underdeveloped, the root quantity is small, and the root group is mostly distributed in the topsoil layer, and the root regeneration ability is weak, and it is not resistant to concentrated fertilizer. Factors such as excessive or insufficient nitrogen fertilizer during the growth period will directly affect the balance between vegetative growth and reproductive growth of pepper plants, which will easily lead to flower drop and other phenomena, which have a great impact on yield. Therefore, pepper fertilization should be carried out scientifically and rationally. The principle of fertilizing peppers is to apply more organic fertilizers and topdressing fertilizers, ...
