Abstract

The invention belongs to the field of slow-release fertilizer, and specifically discloses an efficient slow-release fertilizer for Vulpia myuros on beach saline land. The fertilizer is characterized by including the following components by weight: micron glass fiber, water-soluble nano silica, graystone fiber, alginic acid, weathered coal polyvinyl alcohol complex, ammonium phosphate humic acid, compound microbial inoculant, sodium metasilicate, eucalyptus oil, sepiolite micropowder, potassium feldspar powder, alginate propylene glycol, fermented bran, organic fermented cow dung, fermented vermicompost rich in active substances, hydroxymethyl cellulose, and a proper amount of water. The invention uses weathered coal grafted alginic acid as a basic coating material; and materials in different sizes are added in the coating material, so as to enrich the pore size, hydrophobicity and adsorbability of the coating material, and improve the regulation of fertilizer efficiency. The efficient slow-release fertilizer can realize protection of root cells of Vulpia myuros on beach saline land, promote the absorption and utilization of different nutrition materials in environment, and reach efficient cultivation.

Description

technical field [0001] The invention belongs to the field of functional slow-release fertilizers, and in particular relates to a high-efficiency slow-release fertilizer for sage grass in tidal flat salt land 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 degradat...
