Abstract

The invention belongs to the field of slow release fertilizer, and specifically discloses a micron hydrogel micro-nano dual channel regulation fertilizer for fig. The fertilizer is characterized by comprising the following components by weight: nano chitosan modified attapulgite, fish skin peptone, a thickfruit millettia seed or fruit extract, a the root of Chinese pulsatilla extract, a micron silica active powder, a silica powder, black alum, urea formaldehyde foam, molasses powder, fulvic acid, seaweed powder, sweet potato powder, phosphate citric acid residue and sodium peroxide. The invention employs nano chitosan modified attapulgite and urea formaldehyde foam as the basic coating material; the basic coating material is supplemented with substances in different dimensions, such as micrometer composite hydrogel made from fish skin peptone, and silica powder and black alum, so as to enrich the pore size of the coating material, improve the dynamic release properties and nutrient use efficiency of fertilizer, ensure the regulation of fertilizer efficiency, promote absorption and usage of different nutrition by the fig, enrich the nutrition of fig, and promote 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 fig fertilizer regulated by micro-nano dual channels of micron hydrogel 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...
