Description

Technical Field

[0002] Saline-alkali soil is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. In the arid and semi-arid areas of Northeast, Northwest and North China, the precipitation is small and the evaporation is large. The salt dissolved in the water is easy to accumulate on the surface of the soil, forming soil salinization. The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonates in the soil. Therefore, the alkalinity is generally high, and plants in severe saline-alkali soil areas can hardly survive. With the development of industrial technology and the increase of my country's agricultural multiple cropping index, the demand for increasing production has led to a large amount of excessive input of chemical fertilizers in agricultural production, resulting in the inability of crops to fully utilize the applied chemical fertilizers. Most of them are solidified and accumulated in the soil, causing soil compaction and forming secondary salinization hazards in large areas of cultivated land. As we attach importance to food security, farmland protection and the comprehensive development and utilization of a large number of saline-alkali lands, we urgently need corresponding saline-alkali land improvement technologies and improvement measures. At this stage, soil remediation agents will be used to improve saline-alkali soils;

[0026] The specific preparation method of the repair agent is as follows:

[0027] Step 1: Take medical stone and volcanic rock in proportion, use a crushing device to crush the stones, pour them into a grinding device after preliminary crushing to grind the medical stone and volcanic rock into powder, pass through a 200-mesh sieve after grinding, take diatomaceous earth, seaweed residue, fly ash, aluminum sulfate and calcium oxide and pour them into the powder, and mix them together;

[0028] Step 2: Take white thorn, Yuanshen, wolfberry, Cassia, realgar, gastrodia, Lianchi, Achyranthes and garlic powder, place them in a drying device, adjust the temperature of the drying device to 120-180 degrees Celsius, continue drying for 40-60 minutes, pour them into the inside of a grinding device after drying, and grind them into Chinese medicine powder that can pass through a 200-mesh sieve;

[0029] Nitraria thornii: It has strong adaptability, is drought-resistant, cold-resistant, and barren-resistant, and likes saline-alkali soil. It is an ideal greening plant for wasteland reconstruction and construction, especially suitable for planting in saline-alkali land. It has a well-developed root system, strong reproductive ability, and high yield.

[0030] Yuanshen: It is extremely resistant to salt and alkali, and also has strong drought resistance. The planting technology is simple, and it can be mechanized and planted on a large scale to speed up the transformation of saline-alkali land. It has a large market demand and does not affect the yield. It is an ideal variety for planting in saline-alkali land.

[0031] Wolfberry: It is cold-resistant and drought-resistant, and can grow in areas with extremely low or high temperatures. Although it is more economically profitable to plant it in fertile soil, it is also suitable for planting in saline-alkali land. Its quality and yield are excellent in saline-alkali land and sandy loam.

[0032] Cassia: It has strong vitality and lives in adverse environments such as hillsides and sandy land. It has salt-alkali resistance and grows well in saline-alkali land.

[0033] Step 3: Mix the product obtained in step 1 and the product obtained in step 2, control the stirring speed of the stirring device to 60-80 rpm, pour the biomass, nutrient, microbial agent, montmorillonite powder, citric acid residue, trace element fertilizer, sodium ion adsorbent and biochemical polymer compound into the mixture, and continue stirring for 8-10 minutes;

[0034] The role of microbial agents in improving soil acidity and alkalinity is mainly reflected in the following aspects:

[0035] Providing organic matter: The microorganisms in the microbial agent can decompose the organic matter in the soil and release organic acids, which play an important role in inhibiting the pH of the soil. Organic acids can neutralize excess hydrogen ions in the soil and reduce the acidity of the soil;

[0036] Decomposition of harmful substances: The microorganisms in the microbial agents can decompose harmful substances in the soil, such as biosulfur, toxic metal ions, etc., and reduce their impact on the pH value of the soil. At the same time, the microbial agents can also decompose the pesticide and fertilizer residues in the soil, improve the ecological environment of the soil, and regulate the pH value of the soil;

[0037] Promote soil structure stability: Microbial agents can secrete adhesive substances, promote the aggregation of clay particles in the soil, increase soil stability and anti-erosion ability, which can reduce the loss and migration of soil particles, maintain the activity of microorganisms and plant roots in the soil, regulate soil gas exchange and water cycle, and reduce soil pH;

[0038] Regulating soil moisture: Microbial agents can promote the penetration and retention of soil moisture, increase the soil's water holding capacity, and during droughts, by regulating soil pH, reduce soil evaporation, maintain soil moisture content, reduce soil acidity, and improve soil drought resistance.

[0039] The effect of montmorillonite powder on soil acidity and alkalinity improvement is mainly reflected in its neutralization of acidic substances in the soil, thereby effectively improving the soil pH.

[0040] As an environmentally friendly mineral material, montmorillonite powder has a special crystal structure and excellent properties, such as surface adsorption, ion exchange, expansion and acidity and alkalinity, which make it have a significant effect in improving soil. Specifically, the mechanism of action of montmorillonite powder on soil acidity and alkalinity improvement includes:

[0041] Surface adsorption: Montmorillonite powder has a large number of pores and channels in its unique crystal structure of environmentally friendly mineral materials, forming a high surface energy. Through the action of electrostatic force and dispersion force, it exhibits strong adsorption performance. This adsorption capacity not only helps to retain water, but also can repair soil heavy metal pollution to a certain extent;

[0042] Ion exchangeability: On the surface, internal pores or interlayer domains of montmorillonite powder, some cations are easily replaced through ion exchange without destroying the mineral crystal structure. This ion exchange can control the absorption and release of ammonium and other cations in fertilizers, improve fertilizer utilization, and also help neutralize acidic substances in the soil;

[0043] Acidity and alkalinity: Due to excessive fertilization, soil acidification is becoming more and more serious. The alkaline cations in montmorillonite powder can neutralize the acidic substances in the soil, thereby effectively improving the pH of the soil and providing a suitable environment for the growth and development of crops.

[0044] Step 4: Take the poultry and livestock manure and sterilize it with high-temperature steam for 10-20 minutes. After sterilization, place it inside the drying device and adjust the temperature of the drying device to control it at 180-200 degrees Celsius. When the internal water content of the poultry and livestock manure drops to 5-8%, crush it and grind it into powder, and mix it with the above mixture to obtain a repair agent.

[0045] The repair agent in this application has three major functions:

[0046] 1. Regulate the physiological functions of plant cells and enhance the ability of plants to resist salt;

[0047] 2. Activate the activity of enzymes in plants, promote secretion, and create a good growth environment for plants;

[0048] 3. Activate soil nutrients, convert nutrients and trace elements in the soil into balanced nutrients that can be absorbed and utilized by plants, relieve plant deficiency symptoms, and ensure that plants germinate, grow and develop normally on saline-alkali soil, so that crops will turn green quickly, have rich leaf color and well-developed root systems.

[0049] How to use this repair agent:

[0050] (1) directly sprinkle the repair agent on the surface of the soil, mix the repair agent with the soil through agricultural machinery, or dig a pit on the surface of the soil and bury the repair agent in the pit;

[0051] (2) Take the repair agent, add water in a ratio of 1:50, stir evenly, and spray directly on the soil surface.

[0052] The biomass includes one or more of straw, tree branches and bark, fallen leaves, dead grass residues, and wood chips.

[0053] The nutrient is a mixture of 52-60% wt humic acid, 13-17% wt calcium magnesium phosphate, 13-20% wt carbonate, 10-19% wt potassium dihydrogen phosphate and 2-4% wt ammonium nitrate.
