Abstract

The invention belongs to the field of slow-release fertilizer, and specifically discloses an efficient slow-release fertilizer for Salicornia europaea on beach saline-alkali land. The fertilizer is characterized by including the following components by weight: cyclodextrin oxalate, activated clay, micron hollow glass cellulose powder, mesoporous silica nanoparticles, medical stone silicate, compound amino acid solution, fulvic acid, polypeptide metalloenzyme, ferrous sulfate, biological bacteria, rice husk carbon micropowder, slag, bagasse, vinegar residue, furfural residue, tetracycline mushroom residue, xanthan gum, gypsum powder, sodium dodecyl benzene sulfonate, and a proper amount of water. The invention uses cyclodextrin oxalate and activated clay as a basic coating material; and materials in different sizes including hollow glass cellulose powder, mesoporous silica nanoparticles and gypsum powder are added in the coating material, so as to enrich the pore size, adsorption, acid and alkali resistance of the coating material, and improve the regulation of fertilizer efficiency and fertility. The efficient slow-release fertilizer can promote the efficient cultivation of Salicornia europaea, and achieve efficient cultivation by combination with the main materials.

Description

technical field [0001] The invention belongs to the field of slow-release fertilizers, and in particular relates to a high-efficiency slow-release fertilizer for saline-alkali land on tidal flats and a preparation method. Background technique [0002] Coated slow-release fertilizer can significantly improve the utilization rate of fertilizer. However, the vast majority of slow-release fertilizers currently on the market are facing many problems, for example: 1. The coating material is made of chemically synthesized non-degradable polymers, and these refractory polymer coating materials are easily left in agricultural fertilizers. Soil degradation and serious pollution are caused in the soil; 2. The coating material is made of natural polymer degradable materials, but the slow-release fertilizers made of these natural polymer degradable materials are too expensive on the one hand, and the controlled release effect is not good on the other hand , with the degradation of natur...
