Description

Preparation method of plant life essence

Technical Field

The invention relates to the technical field of plant life science research and preparation of trace element intakes, in particular to a preparation method of plant vital essence.

Background

China is a more traditional agricultural kingdom. The using amount of water and fertilizer is large, and the phenomenon of resource consumption and waste is serious. The problems of serious damage to the nutrition of the land and shortage of water and fertilizer resources are more and more obvious. The water and fertilizer conservation is a major topic of the sustainable development of modern agriculture, forestry and animal husbandry. In order to solve the problem, due to the progress of science and technology in the application of rare earth, the rare earth is paid much attention to the practicalities of people as 'high yield of planting', 'super calcium', 'life vitamin of modern agriculture, forestry and animal husbandry'. A "compound method" is developed, that is, a compound fertilizer of rare earth and nitrogen, phosphorus and potassium fertilizers is used. Also has a trace fertilizer prepared by combining rare earth and other trace elements by a chelating method. Once the two types of novel fertilizers are on the market, the utilization rate of the two types of fertilizers at home and abroad in the aspects of agriculture, forestry, pasturing and the like is always on the rise. Its superiority is also more and more emphasized by people. However, due to the large amount of fertilizer used and the high production cost, the economic pressure on users is also large, and more importantly, the fertilizer belongs to the field of fertilizers with lower technological content. At present, the production process of rare earth fertilizer at home and abroad mainly adopts an acid melting method to produce acid ammonia fertilizer.

The present invention adopts the self-developed production process-water oxidation method to produce the life essential elements for plant growth, development and maturity, which are formed from lanthanide series multielement rare earth oxide. The rare earth oxide element can be widely used in agriculture, forestry and pasturing. The method has the advantages of good production effect, safety, reliability, low production cost and low economic pressure of users. It is a vitamin which is really needed by the life of the agriculture, forestry and animal husbandry plants. The method has high scientific and technological content, small usage amount and great practical effect, and belongs to the scientific and technological pioneer of the front-end application of rare earth resources. The invention is the first case of the development and application of rare earth resources at home and abroad, and makes great contribution to the development of yield increase and harvest of agriculture, forestry and animal husbandry plants. Has practical positive significance for reducing the waste of rare earth resources and protecting the environment.

Disclosure of Invention

In order to solve the above-mentioned drawbacks, the present invention provides the following solutions.

The production process comprises the following technical processes: at present, the mining utilization rate of rare earth ore in China is less than 10% -20%, the invention utilizes the slag eliminated by mineral separation for recycling, which is the targeted application and research result of light rare earth elements and is the result of resource recycling under the guidance of the national idea of vigorous development and cycle and sustainable development. The production process flow is as follows:

crushing and grinding slag (sieving by a 50-80 mesh sieve), adding water and stirring into a porridge shape, airing in the open air to fully oxidize and dry lanthanide metal oxide, then grinding (sieving by a 100 mesh sieve), blending (adding rare earth oxide to ensure that the blended mixture contains lanthanide metal element with the standard of not less than 0.05 mg/kg), and packaging.

The invention selects light rare earth element slag as raw material, uses water oxidation method to prepare plant life element by 'two-grinding one-sunning' processing technology and uses the function of 'super calcium' given by the composite oxide of rare earth lanthanide to the plant. The composite oxide of lanthanide can be called plant life element because it has the following functions: 1. promoting seed germination and rooting germination; 2. promoting the increase of chlorophyll, improving the product and improving the quality; 3. promoting the growth of plant roots; 4. can promote or delay the maturity of plants and other multiple complex efficacies.

The reserves and the output of the Chinese rare earth resources are at the first place in the world at present. The industrial market scale of rare earth reaches billions of yuan RMB at present, and the share of rare earth fertilizer is very small. Plant life essence prepared from rare earth raw materials is not on the market, and the development prospect is expected to be very wide. At present, rare earth fertilizers have great effects on improving crop yield and enhancing plant disease resistance, and have been praised by people as "high yield element of planting", "super calcium" and "life vitamin of modern agriculture, forestry and animal husbandry", but the investment and attention on scientific research and production are still very insufficient. The invention makes considerable investment and effort in this respect, and makes the plant life essence produced from rare earth slag to make a contribution to the increase in yield and income of useful plant life for human beings in the world.

The invention has the following economic and social benefits:

1. small investment and large output. The invention uses the low-grade slag discarded by the rare earth ore as the raw material, and the investment cost is low. The advanced 'water oxidation method' is adopted in the production technology, the output is large, and no environmental pollutants such as waste water, gas, slag and the like are discharged. Inner Mongolia Baiyunebo ore is taken as an example: the ore utilization rate is less than 10%, the rest 90% is piled up and buried, and the invention can recycle 100% of the waste slag.

2. The rare earth fertilizer accounts for less than 1% in the market scale of rare earth industry of billions of yuan RMB in China, so that the market prospect of the plant vitals produced by the rare earth slag is wide.

3. Years of experiments prove that by applying a proper amount of plant vital essence, the germination of seeds can be promoted, the germination rate of the seeds can be improved, the growth of seedlings can be promoted, the chlorophyll content of plants can be increased, the photosynthesis can be enhanced, the development of root systems of the plants can be promoted, the absorption of the root systems to nutrients can be enhanced, the absorption, the conversion and the utilization of the plants to the nutrients can be promoted, and the yield of grains, oil crops, fruits and vegetables, trees and flowers and grasslands and crops can be increased considerably.

4. The market prospect is wide, the Chinese rare earth resource accounts for about 40% of the world resource amount, and the production of the Chinese rare earth product accounts for more than 90% of the world total amount. The rare earth separation technology in china is the first in the world. At present, the production of rare earth fertilizer in China is mainly ammonium sulfate. The rare earth compound fertilizer is a new variety which shows a huge market demand just coming into the market, so that the market of the rare earth compound fertilizer is wide after the rare earth compound fertilizer is put into the market on a large scale.

5. The contribution of the invention to environmental protection is huge. The utilization rate of the existing rare earth ore in China is between 10 and 20 percent, a large amount of rare earth resources are wasted, and the rare earth ore is piled up and buried, so that vegetation is seriously damaged. The separation technology of the acid melting method generates a large amount of waste acid, ammonia water and salt slag, and causes serious pollution to land and air. The invention can utilize 100% of low-grade slag, and reduces damage to vegetation. The 'water oxidation method' has no pollution of waste water, gas and slag to the environment, effectively protects the land, the atmosphere and the environment, and enhances the secondary utilization of rare earth resources.

In conclusion, the advancement of the process technology and the product prospect of the invention are remarkable. The invention can be invested in a large scale, is developed vigorously, can solve the employment pressure of part of society, and has large scale for generating economic benefit. The invention has great contribution to the development of world economy and agriculture, forestry and animal husbandry at home and abroad, has obvious social benefit, and is a good invention benefiting the nation and the people. The methods of use and the technical parameters for the application of the products created by the present invention to various plants are not set forth in this application, see expect.
