Method for producing rare earth microelement fertilizer by using remediation plant Dicranopteris dichotoma, produced Dicranopteris dichotoma ash residue rare earth microelement fertilizer and application

Abstract

The invention discloses a method for producing a rare earth microelement fertilizer by using remediation plant Dicranopteris dichotoma, the produced Dicranopteris dichotoma ash residue rare earth microelement fertilizer and application of the fertilizer. The method comprises the following steps: cutting and collecting the overground part of Dicranopteris dichotoma, conducting drying, collecting Dicranopteris dichotoma leaves, conducting crushing, conducting burning at high temperature, and collecting ash residue to prepare the Dicranopteris dichotoma ash residue rare earth microelement fertilizer. The Dicranopteris dichotoma ash residue rare earth microelement fertilizer with excellent quality is successfully applied to yield increase and quality improving of vegetables. The ash residue isrich in potassium, rare earth, nano carbon, silicon and the like, contains a certain amount of radioactive elements, is beneficial to plant growth, can remarkably increase the yield and improve the quality, and ensures that the contents of rare earth, heavy metals and radioactive elements of harvested vegetables are lower than the national standard of food safety. The Dicranopteris dichotoma ashresidue rare earth microelement fertilizer produced and prepared by the method is low in production cost, simple and convenient to use, good in vegetable crop yield increasing and quality improving effect, multiple in fertilizer effect and suitable for different soil and crops.

Description

technical field [0001] The invention belongs to the production and application of bio-environmental protection and agricultural fertilizers, and in particular relates to a method for producing rare earth micro-fertilizers by using repairing plants Osmanthus osmanthus and the produced Osmanthus ash and residue rare earth micro-fertilizers and their application. Background technique [0002] Plant ash is made by burning straw, which is a commonly used source of fertilizer in traditional agriculture. It is also an ecological fertilizer, just like another commonly used source of fertilizer in traditional agriculture, "organic fertilizer". Rational use of plant ash fertilizers not only makes use of crop stalks for environmental protection, but also saves fossil energy for energy companies. Plant ash fertilizer is rich in potassium, phosphorus and other macronutrient elements necessary for the growth of crops, as well as medium and micronutrient elements, such as iron, manganese, ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, generally speaking, the reasons why researchers avoid studying Osmanthus ash fertilizer are as follows: 1. The harmful elements in Osmanthus may be harmful to the growth and development of crops; 2. The rare earths in Osmanthus may be harmful to the growth and development of crops due to Hormesis; 3. Allelochemicals in Osmanthus may be harmful to crop growth and development; 4. Negative impact of melting and slagging during Osmanthus ash preparation on ash fertilizer preparation and ash fertilizer efficiency
