A kind of planting method of rice with high SOD content, fertilizer for planting

technical field

The invention relates to the technical field of agricultural planting, in particular to a method for planting rice with high SOD content, and also relates to a fertilizer for planting rice with high SOD content.

Background technique

Superoxide dismutase (SOD) is an important antioxidant enzyme in organisms. SOD is regarded as the most magical enzyme in life sciences and the garbage scavenger in the human body, which can eliminate harmful substances produced by organisms during metabolism .

SOD is the natural enemy of oxygen free radicals, the number one killer of oxygen free radicals in the body, and the foundation of life and health. It has been confirmed that there are as many as 60 kinds of diseases caused by oxygen free radicals. It is believed that free radicals (also known as free radicals) are related to most diseases and the aging of the human body. The so-called free radical is that when the body is metabolizing, it can take away an electron from oxygen, so that the oxygen atom becomes a free radical. Free radicals are very unstable. They have to snatch electrons from molecules in body tissue cells to pair themselves. When a cell molecule loses an electron, it also becomes a free radical, and it wants to snatch electrons from cell membrane or nucleus molecules. , which will generate new free radicals, such as superoxide anion radicals, hydroxyl radicals, hydrogen radicals and methyl radicals, and so on. Because free radicals are very active and chemically reactive, they participate in a series of chain reactions, which can cause lipid peroxidation on the cell biomembrane, destroying the structure and function of the membrane. It can cause protein denaturation and cross-linking, make many enzymes and hormones in the body lose their biological activity, reduce the vitality of the body's immunity, nerve reflexes, exercise ability and other systems, and at the same time destroy the nucleic acid structure and cause metabolic disorders in the whole body, etc. Eventually, the body will become diseased. Therefore, free radicals, as human waste, can promote the occurrence of certain diseases and the aging of the body. Superoxide dismutase (SOD) is a free radical scavenger, which can scavenge free radicals O ₂ ^‐ (superoxide anion free radicals), and O ₂ ^‐ has cytotoxicity, which can cause lipid peroxidation, damage cell membranes, and cause inflammation. Tumors and autoimmune diseases, and may promote the aging of the body. SOD can resist and block the damage to cells caused by oxygen free radicals, repair damaged cells in time, and restore the damage to cells caused by free radicals.

Experiments have proved that SOD can scavenge free radicals. The reaction process is that superoxide anion free radicals, which are harmful substances, react with hydrogen ions under the action of SOD to generate another substance-hydrogen peroxide. Hydrogen peroxide will react with _O2 under the action of iron chelate to generate ‐OH, which is very harmful to human body, so it is necessary to further remove the generated hydrogen peroxide.

Catalase (CAT) is an enzyme that catalyzes the decomposition of hydrogen peroxide into oxygen and water. Its main function is to catalyze the decomposition of H ₂ O ₂ into H ₂ O and O ₂ , so that H ₂ O ₂ will not be separated from O ₂ Under the action of iron chelate, the reaction generates ‐OH which is harmful to human body, which is one of the key enzymes in the biological defense system. Catalase is the marker enzyme of peroxisome, accounting for about 40% of the total amount of peroxisome enzymes. Peroxidase (POD) is a class of oxidoreductases produced by microorganisms or plants, which can catalyze many reactions. Peroxidase is an enzyme that catalyzes the oxidation of substrates with hydrogen peroxide as the electron acceptor. It can catalyze the oxidation of phenols and amines with hydrogen peroxide, and has dual functions of eliminating the toxicity of hydrogen peroxide, phenols and amines. Glutathione peroxidase (GSH‐Px) is an important peroxidase that exists widely in the body. The active center of GSH‐Px is selenocysteine, and its activity can reflect the selenium level in the body. . Selenium is a component of the GSH‐Px enzyme system, which can catalyze GSH into GSSG, reduce toxic peroxides to nontoxic hydroxyl compounds, and promote the decomposition of H ₂ O ₂ , thereby protecting the structure and function of cell membranes. Interference and damage by peroxides. Catalase, peroxidase, glutathione peroxidase all help to remove the hydrogen peroxide that is produced. Therefore, SOD is combined with catalase, peroxidase, and glutathione peroxidase to form a set of antioxidant enzymatic system in the body, and the effect is better.

Due to the pressure of modern life, environmental pollution, and various radiations, etc. will cause a large number of oxygen free radicals to form in the human body, therefore, proper intake of SOD, catalase, peroxidase and glutathione peroxidase is beneficial to Human health is very beneficial. At present, there are related supplementary health products, but on the one hand, the price is relatively high; on the other hand, for modern people who are increasingly pursuing health, people very much hope to replace medicine supplements with food supplements. Rice is one of the staple foods in our country. Supplementing SOD, catalase, peroxidase and glutathione peroxidase through rice with high content of enzymes can make the supplementation process more durable, the effect is more obvious, and it is easier Persistence, and the cost is very low, easy to be accepted by ordinary consumers, so it is one of the best ways to supplement. Based on the above reasons, it is necessary to provide a planting method of rice with high SOD content.

The planting method of rice with high SOD content provided by the invention is designed according to the growth characteristics of each growth period of rice. Rice belongs to the grass family and likes silicon dioxide. For example, the ash content of silicon dioxide in rice reaches 61.4%. Therefore, it is necessary to apply a large amount of silicon-calcium-magnesium fertilizer as the base fertilizer of rice fields to meet the demand for silicon in the growth process of rice. The advantages of applying silicon calcium magnesium fertilizer are introduced as follows. Silicon-calcium-magnesium fertilizer can improve soil, correct soil acidity, restore soil, increase soil base, promote organic fertilizer decomposition, inhibit soil bacteria, and play a good role in regulating surface alkalinity and heavy metal pollution. Silicon-calcium-magnesium fertilizer can silicify the epidermal cells of crops, make the stems and leaves of crops straight, reduce shading, and enhance photosynthesis of leaves. After applying silicon-calcium-magnesium fertilizer to rice, the angle of leaves decreases, and canopy photosynthesis can increase by more than 10%. After the crop absorbs silicon, silicified cells are formed in the body, the cell wall of the stem and leaf surface is thickened, and the cuticle is increased, thereby improving the ability to resist insects and diseases, especially resistance to rice blast, rice smut, leaf spot, stem rot, etc. Silicon calcium magnesium fertilizer also has anti-lodging effect, and can also improve the stress resistance of crops, such as drought resistance, dry hot wind resistance, etc. For rice, the application of silicon-calcium-magnesium fertilizer has a significant effect on increasing production. Rice is a silicon-loving crop. After application, rice epidermal cells can be thickened, the stems and leaves of the crop are thick and straight, the root system is developed, the leaves are raised, photosynthesis is enhanced, and effective tillering, High seed-setting rate, large ears and many grains, drought resistance and lodging resistance increased by more than 85%, early maturation is promoted, rice quality is improved, and disease and insect pest resistance can be reduced by 75%. The application of silicon calcium magnesium fertilizer can also promote the increase of SOD and CAT content in plants. Rice is very sensitive to zinc throughout its life. If it is deficient, seedlings will form and the tillering will not be good. Therefore, it is necessary to spray zinc fertilizer in the tillering stage - amino acid complex zinc. The form of amino acid complex zinc is more easily absorbed by plants and has a high utilization rate. Rice needs trace element B during the flowering period. If there is a lack of boron, the rice will only flower, but the fruit will not be full, so boric acid needs to be sprayed. In rice tillering stage and rice heading and flowering stage, amino acid needs to be supplemented, and the effect is better.

Applying trace elements in each growth period of rice can increase the content and activity of various enzymes in the plant, improve the ability of the plant to resist pests, dry hot wind and drought, and make the plant produce enough SOD, CAT, POD, GSH‐Px enzymes promote a significant increase in the content of these enzymes in rice grains at the mature stage. The trace element titanium can participate in activating the activity of some enzymes. Titanium has the property of changing valence and plays the role of electron transfer in redox reaction. Spraying titanium fertilizer can increase the activity of catalase (CAT), peroxidase (POD), nitrogenase, and nitrate reductase in plants, thereby promoting nitrogen fixation of crops and physiological metabolism in plants, which is beneficial to rice grains. Increased content of various enzymes in Cobalt is related to the activation of certain hydrolytic enzymes in seeds and certain enzymes in crops. Cobalt can prevent the destruction of indole acetic acid and is related to the promotion of cell growth. Cobalt can promote a certain stage of the effective energy ATP synthesis reaction. It can significantly promote the germination, growth and respiration of the crops, enhance photosynthesis, promote the fullness of the grains of crops, increase the yield and improve the quality. The application of cobalt fertilizer can improve the growth, transpiration and photosynthesis of rice and other crops, and increase the reduction activity and catalase activity. Low concentrations of selenium can promote the growth of some crops and induce the production of proline, which prevents the synthesis of malondialdehyde (MDA). Exogenous selenium may affect the type, quantity or enzyme activity of certain microorganisms in the soil, and then affect the nutrient environment for crop growth. By affecting the absorption of nutrients by plants, it will eventually affect the yield and quality of crops. Selenium has an effect on various enzymes in plants, and the effect on enzyme activity is related to its concentration. Selenium can improve the activity of glutathione peroxidase, whose activity center is selenocysteine, and the activity of this enzyme is restricted by the content of selenium. Low concentration of selenium can significantly increase glutathione peroxidase activity in rice tillering and booting stages. The results of hydroponic experiments showed that appropriate amount of selenium can also increase the activities of superoxide dismutase (SOD) and peroxidase (POD) in rice seedling leaves. Experiments have proved that selenium has antioxidant effect on higher plants, thereby enhancing the antioxidant capacity of the plant, improving the stress resistance and anti-aging ability of the plant, and ensuring the normal growth of the plant. Studies have also shown that selenium can resist the influence of adversity factors by starting specific genes related to GSH-Px synthesis, increasing enzyme content and enhancing enzyme activity. The activity of peroxidase (POD) was also affected by the concentration of selenium, and low concentration of selenium had the effect of activating peroxidase. Studies on rice have shown that the content of membrane peroxidation product MDA, the production rate of O ₂ ^- and the amount of free radicals all decrease with the increase of selenium concentration, indicating that selenium can eliminate excessive free radicals in plants and prevent excessive Oxidation plays an important role. The antagonism of selenium on heavy metals is manifested in three aspects: (1) combining with heavy metals to form insoluble precipitates; (2) reducing the inhibitory effect of heavy metals on antioxidant enzymes in plants, thereby reducing the damage of free radicals to plants; (3) Participate in regulating the activity of plant chelating peptidases, which can form chelating proteins with heavy metal ions to alleviate the toxicity of heavy metals to plants. In addition, selenium and arsenic have a large chemical affinity, and a relatively stable and low-toxic selenium-arsenic complex may be formed in plants, thereby reducing the inhibitory effect of arsenic on the activity of antioxidant enzymes. Amino acids can promote the absorption of selenium by plants, while adding humic acid can reduce the content of selenium in plants. Trace element manganese is an important component of SOD enzyme, and each SOD molecule contains a manganese atom. Trace element copper exists in superoxide dismutase (SOD) and is an important component of SOD.

The beneficial effects of the present invention are: the planting method of rice with high SOD content provided by the present invention, according to the growth characteristics of each growth period of rice, by applying different fertilizers, to promote the growth of SOD, CAT, POD, GSH-Px in the rice growth process. Synthesis of these enzymes, and transfer to rice grains, and finally obtain rice products with high content of SOD and other four enzymes. After testing, the activity content of SOD, CAT, POD, GSH-Px enzymes in the rice products obtained by the planting method of rice with high SOD content provided by the present invention is all significantly improved, wherein the activity of SOD enzyme reaches more than 20.5U/mg, and the activity of CAT The activity of the enzyme reaches above 4.0U/mg, the activity of the POD enzyme reaches above 7.5U/mg, and the activity of the GSH‐Px enzyme reaches above 6.5U/mg.
