Problems solved by technology

Wastewater contains a large amount of organic substances, which will consume dissolved oxygen in the water after being discharged into natural water bodies, deteriorating water quality and increasing environmental burden
Foliar fertilizer, as the name suggests, sprays the fertilizer on the leaves. After the fertilizer is sprayed, it is easy to slide into the soil. The time of leaf fertilizer soaking is short and the absorption rate is low, resulting in low utilization rate of fertilizer.

Abstract

The invention belongs to the technical field of fertilizer, in particular to eco-friendly foliar fertilizer applied to vegetables or fruits and a preparation method of the eco-friendly foliar fertilizer. The foliage fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of beer wastewater, 0.2-0.3 parts of urea, 2-3 parts of silkworm excrement, 6-8 parts of potatoes, 0.1-0.2 parts of zinc citrate, 0.2-0.3 parts of magnesium sulfate and 70-80 parts of water. Useful resources in waste liquid are fully utilized, resource recovery is realized, waste is changed intotreasure, and pollution loads are reduced; the prepared foliar fertilizer can obviously improve quality of the vegetables or the fruits, has high yield increasing rate, reduces environmental pollution and realizes sustainable development of the environment.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an eco-friendly foliar fertilizer applied to vegetables or fruits and a preparation method thereof. Background technique [0002] Foliar fertilizer is a general term for a type of fertilizer that is sprayed on the leaves of vegetables or fruits during the growing season. It has the characteristics of low dosage and high utilization rate. At present, there are many kinds of foliar fertilizers on the market, most of which are compounded with water-soluble quick-acting fertilizers such as urea and ammonium sulfate. Multiple uses and abuses have caused high residual amounts in vegetables or fruits, and are prone to food safety issues. [0003] Beer waste liquid is the waste water discharged from the process of pressing and separating malt in the process of beer preparation. Wastewater contains a large amount of organic substances, which will consume dissolved oxygen ...
