Abstract

The invention belongs to the slow-release fertilizer field, and specifically discloses a slow-release fertilizer for sunflower prepared from micro nano dual-channel coating material. The slow-release fertilizer is characterized by including the following components by weight: 5-6 parts of alkyl chloride, 50-52 parts of straight chain starch, 8-9 parts of mesoporous silica nanoparticles, 8-9 parts of micron spherical carbon, 40-43 parts of peanut bran, 50-52 parts of Camellia shell ferment powder, 50-52 parts of bagasse ferment powder, 20-22 parts of dry ginger submicron powder, 23-25 parts of drying seaweed powder, 3-4 parts of proline, 3-4 parts of cysteine and 2-2.2 parts of polymeric boron. The crosslinking modified amyloseh is supplemented with two sizes of substances in micron size and nano size to construct a dual-channel slow-release coating material, so as to increase the slow-release regulation and control effect and delay the disintegration rate of the slow-release coating material to certain degree. The fertilizer improves regulation and control effect and realizes respective utilization of different nutrients in different growth stages of sunflower.

Description

technical field [0001] The invention belongs to the field of slow-release fertilizers, and in particular relates to a sunflower high-efficiency slow-release fertilizer prepared by using a micro-nano double-channel coating material 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 ha...
