Description

Technical Field

[0001] The present invention relates to the technical field of rice planting, and more particularly to a rice diatom fertilizer and a preparation method and application thereof. Background Art

[0002] Soil and fertilizer are the material foundation of agricultural production. Soil quality and fertilization levels are crucial for crop yield, product quality, safety, economic benefits, and the ecological environment. Soil and fertilizer technologies are crucial for improving farmland quality and ensuring scientific fertilization practices.

[0003] According to statistics, excessive application of nitrogen fertilizer in rice cultivation is common, and in some areas the amount of nitrogen fertilizer used exceeds the actual demand of the crop by 30%-50%.

[0004] However, long-term excessive use of chemical fertilizers can lead to soil acidification and compaction, destroying soil structure and reducing its ability to retain water and fertilizer. Furthermore, nitrogen, phosphorus, and other elements in fertilizers enter water bodies through runoff and leaching, causing eutrophication and triggering environmental problems such as algae blooms. Furthermore, excessive fertilizer use not only increases production costs but also reduces fertilizer utilization, resulting in a waste of resources.

[0005] Therefore, how to develop a new type of special fertilizer for rice is a problem that those skilled in the art need to solve urgently. Summary of the Invention

[0006] In view of this, the object of the present invention is to provide a rice diatom fertilizer and a preparation method and application thereof, so as to solve the deficiencies in the prior art.

[0013] (1) Weigh the raw materials according to the weight of the above-mentioned rice diatom fertilizer;

[0014] (2) Mix all the raw materials, ferment them, and compost them to obtain rice diatom fertilizer.

[0015] The present invention also seeks to protect the use of the rice diatom fertilizer or the rice diatom fertilizer prepared by the preparation method in rice planting.

[0016] A method for using the rice diatom fertilizer or the rice diatom fertilizer prepared by the above preparation method specifically comprises the following steps:

[0017] (1) Dividing the rice diatom fertilizer into a solid part and a liquid part;

[0018] (2) All the solid part and one-fifth of the liquid part are used as rice base fertilizer;

[0019] (3) Dilute the remaining four-fifths of the liquid and add baking soda during the tillering, heading, flowering and seeding stages of rice, and then apply fertilizer mainly on the leaves above the roots of the rice seedlings.

[0020] Furthermore, in the above step (2), the dilution ratio is 1:(50-100) times.

[0021] There are five main types of processes for applying diatom fertilizer to rice in the present invention:

[0022] 1. Process for increasing the specific surface area of ​​silicon

[0023] Rice is a typical silicon-loving crop. Silicon is the fourth element in rice's nutrient supply, following nitrogen, phosphorus, and potassium. Therefore, the scientific use of silicon in rice cultivation plays a crucial role. Because silicon has high melting and boiling points, its effectiveness as a silicon fertilizer must be targeted based on its oxidation reaction and porous structure. Under normal conditions, modifying the structure of silicon fertilizer can accelerate its oxidation, achieving rapid release. A key method for modifying the structure of silicon fertilizer is to process and pulverize the silicon ore. The finer the silicon pulverization, the greater its specific surface area, the faster the silicon fertilizer releases oxygen. Furthermore, the porous silicon can store more organic fertilizer, mixed fertilizer, or bacterial fertilizer, which is more beneficial to rice growth. In diatom fertilizers, the diatom ore is typically pulverized to 80 to 100 mesh.

[0024] 2. Make full use of the porous structure of silicon

[0025] Silicon is naturally porous and a non-closed element. This non-closed nature results in strong adsorption, which often leaves silicon in a state of "starvation" early on. Silicon's hunger reveals three aspects: first, it robs the soil of nutrients and microorganisms it can accommodate within its pores. Second, it shares the nutrients within silicon pores. Due to the high activity of microorganisms and the abundance of enzymes in rice roots, silicon, microorganisms, and rice form a nutrient-sharing relationship, ultimately meeting the needs of rice growth and development. Third, it consumes nutrients. The more silicon fertilizer is oxidized in rice fields, the greater its chances of sharing the "food" it consumes, and the faster it is ultimately consumed, which undoubtedly benefits rice growth.

[0026] 3. Provide scientific matching of silicon

[0027] The process of scientifically pairing silicon with silica is a revolutionary technology. When crushed into powder, silica possesses a vast surface area and enormous adsorption capacity. However, silica's high melting and boiling points present a practical problem: its inertness. To overcome this inertness, a material with a surface area roughly equivalent to its own must be found. After comparing dozens of materials, the choice of bamboo powder was a perfect match. When crushed to 100 mesh, bamboo powder, before decay, has a surface area less than 15% lower than that of 100 mesh silica powder, and its adsorption capacity is almost identical to that of silica. Because the glycogen in bamboo powder is particularly attractive to microorganisms, numerous microorganisms and their active enzymes adhere to its surface. This nutrient competition between silica and bamboo powder creates a tug-of-war, stimulating the optimal release of their adsorption capacity. When the stalemate reaches a certain point, the silicon accelerates oxidation, nutrient volatilization, and the bamboo powder eventually decomposes. Ultimately, both materials serve as nutrients for rice. The most dramatic scene, of course, was the bamboo powder. It turns out that both rice and bamboo belong to the grass family. Rice possesses life during cultivation; bamboo powder, when paired with silicon and rice, exhibits glycogen and enzyme activity. This fusion of life and biological activity opens a new chapter in plant ecology.

[0028] 4. Maintain the activity of bacterial fertilizer to the maximum extent

[0029] In diatom fertilizers, silicon has a limited application limit; applying more doesn't guarantee a better effect. However, bacterial fertilizers, on the other hand, have significant potential for growth under certain circumstances. Therefore, enhancing microbial activity requires increasing the microbial population itself. Therefore, selecting the optimal bacterial species is crucial. Diatom fertilizers generally fall into three categories: probiotics, enzymes, and enzymes. With a rich supply of probiotics, enzymes, and enzymes, and with the added support of relevant traditional Chinese medicines, the activity of the fertilizer generally reaches its upper limit.

[0030] 5. Maintain the reproducibility of diatom fertilizer

[0031] If diatom fertilizers can't be replicated, there's no industrial chain. Therefore, a reproducible process is a prerequisite. Of course, there are two constraints to the replication of diatom fertilizers: low cost and simple processing. Precisely because diatom fertilizers meet both of these requirements, they can be easily replicated, becoming a popular product, and they can be replicated stably and sustainably, creating a wide variety of products. To date, the products that can be replicated include granules, aqueous solutions, aerosols, and powders, which generally meet the needs of rice production.

[0032] The development and application of the rice diatom fertilizer of the present invention are based on a series of unique advanced technologies. Among them, the main technical components are divided into four categories:

[0033] 1. Biotechnology

[0034] Rice absorbs silicon fertilizer primarily through enzymes secreted by its roots. Therefore, enzyme preparation technology plays a key role in the development of diatom fertilizer for rice. The raw material ratios for diatom fertilizer indicate that it contains enzymes such as amylase, saccharifying enzyme, and protease, all produced by microorganisms. Under certain conditions, microorganisms can produce these enzymes, but they also consume them for their own survival and production needs. This consumption of enzymes inevitably involves the production of an oxidase. Only when the oxidase reaches a certain level does its release effect become apparent, efficiently and rapidly oxidizing silicon, releasing its nutrients. Only at this stage can the rice absorb the silicon nutrients. Therefore, the core of this biotechnology lies in selecting the right microorganisms and maintaining their vitality.

[0035] 2. Life Science (Technology)

[0036] In rice diatom fertilizer, it's the rice and the microorganisms that experience life phenomena and a life cycle. Rice is a nutrient consumer. While microorganisms also consume nutrients, their output often exceeds their consumption. Therefore, to ensure mutually beneficial growth for both rice and microorganisms, targeted conditions must be provided. The most effective approach is to utilize small-molecule peptide technology. Rice polysaccharide protein powder, a major component of which is small-molecule peptide nutrition, benefits both microbial growth and rice's conversion and utilization, ultimately achieving high and stable rice yields.

[0037] 3. Disproportionation technology

[0038] The bamboo powder used in diatom fertilizer utilizes authentic disproportionation technology. Initially, the bamboo powder's enormous surface area attracts microorganisms, diatoms, and nutrients from the fertilizer's raw materials. Simultaneously, it counteracts the diatoms' adsorption, effectively removing their inertia. Once fully utilized, the bamboo powder continuously soaks and corrodes in the rice paddies, eventually becoming organic fertilizer absorbed by the rice plants. The process of bamboo powder transforming from an adsorbent to nutrients is a disproportionation process, a process that shifts from yes to no and ultimately returns to yes. This disproportionation technology holds significant value in the use of diatom fertilizers.

[0039] 4. Inter-process technology

[0040] The core technology behind diatom fertilizer and its application in rice cultivation lies in inter-process technology. According to the principles of inter-process technology, when "0" is transformed into "Q," a fundamental change occurs. Diatoms utilize their porosity and strong adsorption properties to attract microorganisms within and around their pores. Ultimately, the large amounts of enzymes released by the microorganisms oxidize the silicon and release nutrients, increasing rice yield and improving rice quality, fully demonstrating their value. This process is irreversible, and all technologies and management associated with it will be tested for authenticity and falsehood.

[0041] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] The rice diatom fertilizer of the present invention can replace 85% of the total amount of chemical fertilizers, reduce the amount of pesticides used by 85%, reduce the production cost input by 35%, effectively improve the soil, enhance the formation of soil aggregate structure, increase rice production by 10%-15%, improve the rice yield by 5%-7%, and increase the protein content by 3%-5%. The rice is strong and full with a mellow taste. The rice quality can be greatly improved from the source, thereby quickly achieving the goal of a good planting ecology to the greatest extent possible. DETAILED DESCRIPTION
