Description

Salt-alkali tolerant plant growth promoter

technical field

The invention relates to soil fertilization technology, in particular to a saline-alkali-tolerant plant growth promoter which uses super-concentrated straw vinegar as a raw material.

Background technique

Saline soil or alkaline soil is a type of soil in which the pH value of the soil is high and it is difficult for crops to grow after the concentration of soluble salts or substitutable sodium ions in the soil reaches a certain level. The problem of soil salinization is widespread in the world. There are about 27 million hectares of saline-alkali land in my country, mainly distributed in the northeast, north, northwest inland areas and coastal areas north of the Yangtze River. Among them, there are about 0.06 million hectares of saline-alkali cultivated land, million hectares of saline-alkali wasteland. In addition, in arid and semi-arid areas, due to the continental climate, precipitation is scarce, and evaporation is strong. If irrigation measures are not appropriate, such as a large amount of fertilizer input, secondary soil salinization is also prone to occur.

Salinization makes the physical and chemical properties of soil worse, mainly manifested in the increase of soil salt content and pH, the relative decrease of soil organic matter content, the deterioration of nutrient supply conditions, and the inhibition of soil microbial activities, making it difficult for crop roots to absorb water and input fertilizers. Nutrients, causing physiological drought and nutrient deficiency, causing the growth and development of crops to be inhibited by salt damage, which has a negative impact on plant growth, resulting in the lack of seedlings of crops (plants) planted in saline soil, weakened plant growth, and reduced production. Even extinct. Specifically, the main damage caused by saline-alkali environment to plants is manifested in the following three aspects: First, the salt ions in saline-alkali soil will cause physiological toxicity, because plants absorb a large amount of sodium ions (Na ⁺ ), chloride ions (Cl ^- ) etc., thereby destroying the ion balance in the plant cells, and inhibiting the physiological and biochemical metabolic processes in the cells, resulting in a decline in the photosynthetic ability of plants; second, due to the increase in soil salinity, the concentration of soil solution increases and the osmotic pressure continues to increase, resulting in plant The ability to absorb water from the soil is weakened, resulting in "physiological drought"; the third is that the pH value of the saline-alkali soil is high, which makes the acid-base imbalance between the plant and the external environment.

Therefore, in order to effectively reduce the damage of saline-alkali environment to plants, on the one hand, plants subjected to saline-alkali stress need to reduce the accumulation of ions in the cytoplasm; , such as proteins, amino acids, sugars, etc., to enhance the osmotic pressure of the cells, thereby preventing the cells from losing water and stabilizing the structure of the plasma membrane and enzymes.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments.

At present, there are a large number of crop straws in the vast agricultural areas of our country, and the annual return to the field only accounts for about 20% of the total crop straws in the country. Regional, seasonal and structural crop straw surplus. And existing wood vinegar, its preparation raw material multipurpose woody plant (gingko, pine wood etc.), single organic raw material such as bamboo. In the embodiment of the present invention, exploring the use of crop straws to produce super-concentrated straw vinegar can not only make the source of raw materials for making super-concentrated straw vinegar rich and cheap, but also effectively reduce the waste of crop straws such as indiscriminate burning and disposal, and pollute the environment Furthermore, due to the differences in the components of different types of crop straws, by using a variety of crop straws to make super-concentrated straw vinegar, the components will be more diverse, which is more conducive to providing comprehensive nutrients for plants.

Preferably, the carbonization temperature is set not to exceed 350°C, for example, set at 300°C-330°C. Like this, in this temperature range, the yield of straw vinegar is higher, the quality is better, and the amount of harmful substances produced is less, if the temperature is too high, energy will be wasted; and if the temperature is too low, the yield of straw vinegar is low, There are residues of raw material straw, and at this temperature, the yield of super-concentrated straw-vinegar liquid mixture obtained by condensation is relatively high, and the comprehensive cost performance of output, quality and energy consumption is high.

Salinity, thereby improving the yield and quality of crops.

Sugar alcohol is a polyhydroxy compound, which is a natural extract in the phloem juice of plants. It has good metal complexing ability and can combine with various nutrients to form a stable complex. Studies have shown that, on the one hand, sugar alcohol is involved in cell An important substance in endosmotic regulation. For example, under adversity stresses such as salt damage, drought, and flooding, sugar alcohols can make plants adapt to adversity growth by adjusting cell permeability; on the other hand, sugar alcohols can improve resistance to active oxygen and avoid sunburn due to ultraviolet Plant active oxygen damage caused by , drought, disease, hypoxia and other reasons. In the embodiment of the present invention, sugar alcohol and calcium are chelated to generate sugar alcohol calcium. Sugar alcohol calcium is a new type of chelated liquid fertilizer that can provide a large amount of highly soluble calcium ions, which are easily absorbed by plants. Adding exogenous calcium ions to the growth promoter can effectively increase the content of calcium ions in the soil, replace the sodium ions and magnesium ions adsorbed by the soil, play an ion replacement role, and relieve the mineral nutrition stress caused by insufficient calcium ions in saline-alkali land crops , so as to improve the soil structure and permeability, play a role in desalination and inhibit salt return, and can enhance the stability of plant plasma membrane, maintain the normal sending and transmission of calcium signal system, prevent a large amount of sodium ions from entering, thereby maintaining cell ion Balance, improve the salt resistance and drought resistance of plants. Specifically,

Calcium sugar alcohol is the only substance that can carry calcium nutrients in the phloem for transportation. It has a low molecular weight and is easily absorbed by leaves. It is easy to degrade and release nutrients when it enters the plant. It consumes low energy and is stable in liquid form. The liquid state is a stable form of existence. Since the phloem is an alkaline environment, most metal mineral nutrients have poor solubility and mobility in an alkaline environment, and the sugar-alcohol complex can better reflect that it can carry mineral nutrients in the phloem. The advantage of moving; in addition, calcium sugar alcohol has a moisturizing function, which can prevent the liquid from becoming invalid due to rapid drying on the leaves, and prolong the time for the leaves to absorb nutrients; furthermore, calcium sugar alcohol is a natural surfactant, which can make the Nutrient elements spread and evenly cover the entire leaf, increase the absorption area of the leaf, and avoid burning the leaf due to excessive local concentration of micronutrients, thereby improving the stress resistance of the plant.

In the embodiment of the present invention, the sugar alcohol calcium formed by chelating sugar alcohol and calcium can not only play the role of sugar alcohol, but also provide a large amount of highly soluble calcium ions for saline-alkali crops. Mineral nutrition stress caused by insufficient calcium ions in crops can, on the other hand, enhance the stability of the plasma membrane and the normal occurrence and transmission of calcium signaling systems, maintain intracellular ion balance, and enhance the salt tolerance of crops.

Osmoregulation is the stress adaptive response of halophytes to salinity. In a saline environment, plant cells lose water due to high osmotic pressure, causing plants to die due to dehydration. Therefore, in order to improve the survival rate of plants growing in a saline environment, plants need to be able to adjust their own osmotic pressure so that the vacuoles in the body maintain sufficient pressure to prevent cell dehydration. However, halophytes achieve osmotic pressure regulation by ingesting high-concentration salt. The high-concentration salt ingested by plants needs to be limited in the cells, and cannot interfere with various major enzymatic metabolic activities in the cytoplasm outside the nucleus, and the turgor pressure of the cytoplasm and vacuoles. A state of balance must be maintained so that the tonoplast membrane has an insulating effect to prevent the high concentration of salt contained in it from flowing into the cytoplasm. In this way, the cytoplasm must increase the osmotic pressure through osmotic adjustment in order to achieve equilibrium with the high-salt environment. It has been found through research that this osmotic adjustment is through some increased organic substances with similar properties such as proline, glycine, protein, and betaine. Waiting for it.

In the research on various plants, it has been found that under the condition of salt stress, the content of amino acids such as proline, glycine and glutamic acid in plant cytoplasm increases significantly. In particular, proline (Pro) is one of the components of plant proteins, and can widely exist in plants in a free state. That is to say, under stress conditions such as drought and salinity, plants accumulate a large amount of proline. In addition to being an osmotic regulator in the plant cytoplasm, the accumulated proline also plays an important role in stabilizing the structure of biological macromolecules, reducing cell acidity, detoxifying ammonia, and regulating the redox potential of cells as an energy bank. Therefore, under adversity conditions (drought, saline-alkali, heat, cold, freezing), the content of proline in plants increases significantly, that is, the content of proline in plants can reflect the stress resistance and drought resistance of plants to a certain extent. Strong plants have more proline accumulation. Furthermore, because proline is highly hydrophilic, it can stabilize the protoplast colloid and the metabolic process in the tissue, thereby lowering the freezing point and preventing cell dehydration. Therefore, the embodiments of the present invention can effectively improve the stress resistance of plants by adding amino acids such as proline, glycine, and glutamic acid, and promote the synthesis of organic non-toxic osmotic adjustment substances by plants, thereby reducing the salt stress suffered by plants. Among them, in addition to being used as an osmotic adjustment substance in the plant cytoplasm, proline also plays an important role in stabilizing the structure of biological macromolecules, reducing cell acidity, detoxifying ammonia, and regulating the redox potential of cells as an energy bank. Adversity plays an important role, and glutamic acid mainly promotes the synthesis of proline.

Research analysis shows that the accumulation of betaine in plants under salt stress is an important physiological phenomenon that is beneficial to the growth of plants under stress, and its content is positively correlated with plant salt tolerance. Betaine can maintain cell osmotic pressure, protect many enzymes and other biological macromolecules, have persistent salt resistance, and can affect the distribution of inorganic ions, effectively improving the resistance of crop tissues to salt damage. In addition, betaine has a certain regulatory effect on stomatal movement, respiration and related gene expression under adverse conditions.

Abscisic acid can be used as a substance for plants to defend against salt damage, heat damage, and cold damage. It is the "first messenger" that activates the expression of stress-resistant genes in plants, and can effectively activate the stress-resistant immune system in plants. It has the ability of cultivating the source and consolidating the roots, and enhancing the comprehensive resistance of plants (drought resistance, heat resistance, cold resistance, disease and insect resistance, salt and alkali resistance, etc.). It plays an important role in drought resistance and water saving, disaster reduction and production protection and restoration of ecological environment in agricultural production. Under salt stress, through comparative experiments, abscisic acid can induce a large accumulation of plant osmotic adjustment substance proline, maintain the stability of cell membrane structure, and increase the activity of protective enzymes.

In the embodiment of the present invention, by adding calcium sugar alcohols, amino acids, betaine, and abscisic acid to the single super-concentrated straw vinegar solution as a growth promoter for saline-alkali-tolerant plants, the growth of plants in saline-alkali land can be more effectively promoted, and the growth of saline-alkali land can be more effectively promoted. Increased yield and improved quality of plants.

In practical application, the diluent of the saline-alkali-tolerant plant growth promoter can be used to soak seeds, spray foliage, and even root irrigation of saline-alkali land crops, all of which can improve the saline-alkali tolerance of crops and increase yield and efficiency.
