Preparation of composite microbial foliar fertilizer

Abstract

A foliar fertilizer prepared in the invention belongs to a composite microbial foliar fertilizer. After fermentation, a fermentation broth is extracted, and then various elements which are essential to growth of crops are added. The fertilizer has many active materials and has strong plant growth promoting capability. Photosynthetic efficiency is enhanced. The fertilizer contains comprehensive nutrients. Crops are robust and disease-resistant after use of the fertilizer. General output and income increase range is 5-10%. The prepared foliar fertilizer belongs to a composite microbial foliar fertilizer. Components of the foliar fertilizer comprise a microbial inoculant, 1% ammonium molybdate solution, 1% ferrous sulfate solution 5% plant ash leachate, 1% borax solution, gibberellins, 1% lanthanum chloride solution, 1% cerium chloride solution, and 1% magnesium sulfate solution. As the main component is the microbial inoculant, components in a traditional foliar fertilizer which are harmful to the environment are replaced. The foliar fertilizer of the invention is safe to human and livestock and is pollution-free to the environment.

Description

technical field [0001] The invention belongs to microbial foliar fertilizer and belongs to the field of foliar fertilizer preparation. Background technique [0002] Foliar fertilizer is a general term for fertilizers that provide nutrients to crops through the leaves of crops, and can be divided into material nutrient foliar fertilizers and functional nutrient foliar fertilizers. Material nutrient foliar fertilizers are foliar fertilizers that provide trace element fertilizers and hormones, and functional nutrient foliar fertilizers are foliar fertilizers that provide life-origin nutrients for crops. The amount of foliar fertilizer is less, the effect is rapid and obvious, and the utilization rate of fertilizer is improved. [0003] However, the penetration rate of nutrients absorbed by traditional leaves is low, and the amount absorbed is small, especially for leaves with thick cuticles. Foliar fertilization is easy to drip from the leaves, and nutrients are easily leached...

AI Technical Summary

Problems solved by technology

[0003] However, the penetration rate of nutrients absorbed by traditional leaves is low, and the amount absorbed is small, especially for leaves with thick cuticles. Foliar fertilization is easy to drip from the leaves, and nutrients are easily leached by rain, and the spray liquid dries quickly on the leaves. , affecting absorption; some nutrients (such as Ca) are difficult to transfer from the absorption site to other sites; the amount of nutrients provided by foliar application is limited, which is not enough to meet the full needs of crops, especially the macronutrients of nitrogen, phosphorus and potassium; the formulation of foliar application Improper use can easily cause leaf burns; the residual effect of foliar fertilization is short, and multiple sprays are required, which is labor-intensive
