A kind of natural multifunctional foliar fertilizer and its preparation method

Abstract

The invention discloses a natural multi-functional foliage fertilizer. The foliage fertilizer comprises the following raw materials in percentage by weight: 10-30% of Pistacia chinensis extraction solution, 5-10% of amino acid nutrient solution, 1-3% of trace elements, 2-4% of attapulgite, 1-3% of diatomaceous earth, and the balance of water. The invention also provides a preparation method of the foliage fertilizer, the method comprises the steps of taking leaves, buds, twigs and fruit peels of Pistacia chinensis, drying and crushing to fine powder; adding fine powder into the extraction solution at a ratio of fine powder to extraction solution being 1g / (5-40) ml and soaking; after soaking, heating, stirring and extracting, filtering the primary extraction solution and collecting the filtrate; centrifuging the filtrate, collecting the supernatant as the Pistacia chinensis extract solution; taking the raw materials in percentage by weight, mixing the raw material, heating and stirring until the raw materials are fully dissolved. The natural multi-functional foliage fertilizer has the advantages that the foliage fertilizer is natural, green, environmentally friendly and efficient, the yield-increasing effect is obvious, no residues of pesticides and fertilizers occur, the natural multi-functional foliage fertilizer can prevent pests and diseases of plants and is especially applicable to organic agriculture.

Description

technical field [0001] The invention relates to a foliage fertilizer, in particular to a natural multifunctional foliage fertilizer and a preparation method thereof. Background technique [0002] Foliar fertilizer is a type of fertilizer in which nutrients are applied to the surface of crop leaves to exert their functions through the absorption of leaves. Nutrients sprayed on the plant surface can be absorbed into the plant body through the stomata of the plant leaf and the pores in the cuticle, and then transformed and utilized. Plant foliar fertilizers, especially containing certain elements that are easily fixed by the soil such as phosphorus, copper, manganese, iron, zinc, etc., have the characteristics of fast absorption and good effect, which can not only meet the requirements of crop growth and development in time, but also timely Remedial measures for the prevention or correction of certain deficiencies or the need for rapid supply of nutrients due to natural disast...

AI Technical Summary

Problems solved by technology

However, these foliar fertilizers are mainly chemically synthesized substances, less natural, and after being sprayed on the leaves, they are easily lost under the action of rain, wind and sun, causing environmental pollution.

What's more, some foliar fertilizers will cause foliage residue, which is not suitable for organic farming

In addition, the existing foliar fertilizers generally do not have the effect of killing bacteria and insects, and mostly have the effect of promoting growth and development.
