Problems solved by technology

However, most of the slow-release fertilizers currently on the market are facing many problems. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, the coating materials are chemically synthesized. These non-degradable high-molecular polymers, these refractory polymer coating materials are very easy to remain in agricultural soil, causing soil degradation and serious pollution; third, fertilizers are bulky and inconvenient to transport and store; fourth, for special soil environments such as Acid-base, drought-humidity, soil lacking some elements, and nutrient requirements of specific crops are not effectively targeted

Embodiment Construction

[0017] A slow-release fertilizer that enhances the absorption capacity of perennial flower roots, made of the following raw materials in parts by weight (kg): brassinosterol 1.6, chitosan 2.4, rice straw 30, coconut bran 43, enoki mushroom residue 23, sweet potato powder 12. Monoammonium carbonate 7, ferrous sulfate 2, fresh green tea leaves 19, ascorbic acid vitamin C 0.4, acetic anhydride 0.8, 4-dimethylaminopyridine 0.2, water as appropriate.

[0018] The specific steps of the slow-release fertilizer preparation method for enhancing the absorption capacity of perennial flower roots are as follows:

[0019] (1) Expose fresh green tea leaves to the sun for 2 days, crush them and pass through a 0.45mm sieve to obtain green tea powder, add hot water at 94°C according to the ratio of green tea powder to water-material-liquid ratio 1:40g / ml, stir well and place in ultrasonic In the microwave synergistic extraction instrument, the ultrasonic power is controlled to 50W, the microwa...

Abstract

The invention discloses a slow-release fertilizer for improving the perennial flower root absorption capacity. The fertilizer is prepared from, by weight, 1.6-1.7 parts of brassinosteroid, 2.4-.2.6 parts of chitosan, 30-32 parts of rice stems, 43-46 parts of coco coir, 23-25 parts of flammulina velutipes residues, 12-14 parts of sweet potato flour, 7-8 parts of ammonium carbonate, 2-3 parts of ferrous sulfate, 19-21 parts of fresh green tea leaves, 0.4-0.5 part of ascorbic acid, 0.8-1.0 part of acetic anhydride, 0.2-0.3 part of 4-dimethylaminopyridine and a proper amount of water. According to the slow-release fertilizer, brassinosteroid, chitosan and the like are chelated, and permeability and absorption capacity of flower root cell walls can be enhanced after absorption, so that the nutrient absorption capacity of flower roots is improved; under the slow-release action, nutrients in the fertilizer can be provided for flowers for a long time, flower growth is promoted, and resource waste caused when excessive fertilizer is used in the flower planting process is avoided.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer that enhances the absorption capacity of perennial flower roots. Background technique [0002] With the increasing level of modernization of agriculture, coated slow-release fertilizers are widely used because of their remarkable high fertilizer efficiency. However, most of the slow-release fertilizers currently on the market are facing many problems. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, the coating materials are chemically synthesized. These non-degradable high-molecular polymers, these refractory polymer coating materials are very easy to remain in agricultural soil, causing soil degradation and serious pollution; third, fertilizers are bulky and inconvenient to transport and store; fourth, for speci...
