Abstract

The invention discloses a liquid fertilizer taking vinasse, pond residue leachate or waste vegetable oil as a substrate and a preparation method of the liquid fertilizer, and belongs to the technicalfield of organic fertilizers, and the liquid fertilizer is prepared from the following raw materials in parts by weight: 35 to 50 parts of substrate liquid, 6 to 10 parts of a surfactant, 8 to 15 parts of an organic fertilizer, 6 to 15 parts of a chemical fertilizer, 0.2 to 0.6 part of beneficial biological bacteria, and 20 to 40 parts of water. The liquid fertilizer is high in fertilizer efficiency, the effective utilization rate of a traditional fertilizer is only about 27%-33%, and the effective utilization rate of the liquid fertilizer reaches up to 50%-75%; compared with common products,the fertilizer efficiency is higher, and the crop growth vigor is higher. Absorption is rapid, wherein the traditional fertilizer is absorbed by plants 2-3 days after being applied, and the liquid fertilizer is rapidly absorbed by the plants within 2-3 hours.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a liquid fertilizer based on distiller's grains, pond dregs leachate or waste vegetable oil and a preparation method thereof. Background technique [0002] Agricultural production requires soil to provide nutrients for crop growth and a living environment. The application of chemical fertilizers has played a key role in increasing agricultural incomes for many years. However, due to the long-term application of chemical fertilizers, insufficient supply of organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil biota have been damaged to varying degrees, and the quality of agricultural products has been affected to a certain extent. Therefore, chemical fertilizer pollution has become a major public hazard in the world today. The current status of soil resources ...
