Abstract

The invention discloses a double-membrane slow-release fertilizer containing a biostimulant. The double-membrane slow-release fertilizer is prepared from the following raw materials in parts by weight: 50-60 parts of a double-coated fertilizer, 10-20 parts of diammonium hydrogen phosphate and 14-18 parts of a potash fertilizer; and the double-coated fertilizer is prepared from the following components in parts by weight: 85-95 parts of a fertilizer core, 3-7 parts of a coating agent and 4-6 parts of a second coating agent. The invention further discloses a preparation method of the double-membrane slow-release fertilizer containing the biostimulant. The double-membrane slow-release fertilizer containing the biostimulant has double effects of a fertilizer and a pesticide and is complete in nutrient and balanced in release, fruit tree growth can be promoted, metabolism of fruit trees and absorption and utilization of various nutrients are promoted, absorption and utilization of the fruit trees on the nutrients and moisture of soil are improved, the utilization rate of a fertilizer is significantly improved, diseases and pests of the fruit trees can be effectively prevented and controlled, the oxidation-reduction process in fruit tree bodies is accelerated, and the quality of the fruits is significantly improved, thereby achieving the target of increasing both production and income.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a double-film slow-release fertilizer containing biostimulants and a preparation method thereof. Background technique [0002] A biostimulant is a substance that contains certain ingredients and microorganisms, such as microbial agents, alginic acid, humic acid, glutamic acid, etc. These substances are applied to plants to stimulate plant growth and promote plant absorption of nutrients , improve plant yield, improve plant quality, enhance plant stress resistance, reduce fertilizer nutrient loss, improve fertilizer effective nutrient utilization, and improve pesticide efficacy. It is a new type of chemical fertilizer and pesticide synergist. recognized and valued. [0003] Chemical fertilizers play an important role in agricultural production. As "grain food", they support 50% of agricultural output and consume 50% of agricultural investment. It is a modern agricultural integration co...
