Description

Technical Field

[0001] The invention relates to the technical field of resource recycling, in particular to a method for improving soil and increasing sugar beet yield and quality by utilizing sugar mill filter mud. Background Art

[0002] As a crop that requires more fertilizer and nutrients, beets have relatively high requirements for soil during their growth. The soil suitable for beet growth should be neutral or weakly alkaline loam or sandy loam, with good drainage and air permeability, rich in organic matter and effective nutrients, and convenient irrigation regulation.

[0003] Most of the sugar beet factories in my country mainly include two purification processes in the sugar production process, one is the purification process of sugar beets using the sulfite process, and the other is the purification process of sugar beets using the carbonate process. These two purification processes will produce a kind of agricultural waste - filter mud during the clarification process. The filter mud has a high organic matter content, and its main components include sugar beet fiber, sucrose, coagulated colloid, protein, calcium phosphate, etc. However, due to reasons such as deep processing and transportation costs, the filter mud has not been fully utilized, and a large amount of accumulation and storage has not only brought great pressure to the environment, but also wasted resources. The resource reuse of sugar factory filter mud can promote the sustainable development of the sugar industry and has important economic and ecological significance. To this end, the present invention provides a method for improving soil and improving sugar beet yield and quality using sugar factory filter mud. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method for improving soil and increasing sugar beet yield and quality using sugar mill filter mud, which solves the problem that the sugar mill filter mud is currently not fully utilized and is piled up and stored in large quantities, which not only puts great pressure on the environment but also wastes resources.

[0005] To achieve the above objectives, the present invention is implemented by the following technical scheme: a method for improving soil and increasing sugar beet yield and quality by using sugar factory filter mud, comprising the following steps: S1. Material preparation: First, prepare two portions of sugar mill filter mud with the same composition and quality, namely filter mud A and filter mud B; then prepare two portions of soil to be improved with the same composition and quality, namely soil A and soil B; finally, prepare two portions of beet seeds for later use; S2.

Beet planting: sow two beet seeds in soil A and soil B respectively, and then water, fertilize, weed and light regularly to keep the growth conditions of the beet seeds in soil A and soil B consistent; S6. Harvest record: After 80 to 110 days of planting, the beets planted in soil A and soil B were harvested, and the yield and quality of the beets were recorded.

[0006] Preferably, the pH value of the soil to be improved in S1-S2 is 6.5-7.2, that is, neutral or weakly alkaline soil.

[0007] Preferably, the specific methods for treating the filter mud in S3 include: chemical stabilization, biological stabilization, solidification stabilization, leaching and heat treatment.

[0018] See also Figure 1-2 , the present invention provides a technical solution: A method for improving soil and increasing sugar beet yield and quality by using sugar mill filter mud comprises the following steps: S1. Material preparation: First, prepare two portions of sugar mill filter mud with the same composition and quality, namely filter mud A and filter mud B; then prepare two portions of soil to be improved with the same composition and quality, namely soil A and soil B; finally, prepare two portions of beet seeds for later use; S2. Soil analysis: sampling the soil A and soil B to be improved and analyzing their physical and chemical properties; S3, filter mud treatment: perform harmless treatment on the prepared filter mud A and filter mud B to remove any harmful substances that may exist; S4. Soil improvement: Spread filter mud A evenly on the surface of soil A, and then deep plow and mix it to make the filter mud and soil A fully mixed; then apply filter mud B as base fertilizer to soil B, and then cover it with a layer of fine soil; S5. Beet planting: sow two beet seeds in soil A and soil B respectively, and then water, fertilize, weed and light regularly to keep the growth conditions of the beet seeds in soil A and soil B consistent; S6. Harvest record: After 80 to 110 days of planting, the beets planted in soil A and soil B were harvested, and the yield and quality of the beets were recorded.

[0019] By sampling soil A and soil B and analyzing their physical and chemical properties, the standards for planting composite sugar beets in the improved soil can be ensured, that is, the soil is loose, breathable, well permeable to water, and the pH value is between 6.5 and 7.2, which is neutral or weakly alkaline loam; the sugar beets planted in soil A and soil B are harvested uniformly at 109 days.

[0020] In the embodiment of the present invention, the pH value of the soil to be improved in S1-S2 is 6.5-7.2, that is, neutral or weakly alkaline soil.

[0021] In the embodiment of the present invention, the specific method of treating the filter mud in S3 includes: chemical stabilization, biological stabilization, solidification stabilization, leaching and heat treatment.

[0022] Before the filter mud A and filter mud B are harmlessly treated, the filter mud needs to be pretreated first: the humidity of the filter mud is adjusted to facilitate subsequent treatment; the larger particles in the filter mud are screened by screening for physical pretreatment.

[0023] In the embodiment of the present invention, the specific operation of chemical stabilization is: first, lime and dolomite are mixed with filter mud according to a preset ratio; then, a stirring device is used to fully stir and mix so that the lime and dolomite are evenly distributed in the filter mud; finally, the humidity of the mixture is maintained to promote the chemical reaction.

[0024] By adding chemical stabilizers, lime and dolomite, the acidic substances in the filter mud can be neutralized and the bioavailability of heavy metals can be reduced.

[0025] In the embodiment of the present invention, the specific operation of biological stabilization is: first, the filter mud is mixed with crop straw and animal manure; then the filter mud mixture is piled up and covered to create an environment suitable for the growth of microorganisms; and the pile is turned regularly to maintain appropriate oxygen content and temperature in the pile.

[0026] By utilizing the biological transformation of microorganisms, harmful substances in the filter mud can be converted into harmless or less harmful forms; composting through the action of microorganisms can improve the stability of the filter mud.

[0027] In the embodiment of the present invention, the specific operation of solidification and stabilization is: first, the filter mud is mixed with cement or asphalt, and the mixture is fully stirred and mixed by a stirring device to ensure that the cement or asphalt is evenly distributed; after mixing, the filter mud is solidified and cured.

[0028] Specific steps for filter mud solidification and maintenance: Natural curing by watering: Sprinkle water on the surface of the filter mud to keep it moist until the filter mud reaches the required strength; Spray film maintenance: Use curing agent to spray on the surface of filter mud to form a protective film to prevent water evaporation; Plastic film wrapping and maintenance: Cover the surface of the filter mud with plastic film to create a small moist environment to promote chemical reactions inside the filter mud.

[0029] Cement or asphalt can be used to fix harmful substances in the filter mud and reduce their solubility and mobility.

[0030] In the embodiment of the present invention, the specific operation of eluting is: first, the filter mud is piled on the elution bed, and the elution bed should have an impermeable layer to collect the eluent; then, water or a specific solution is used for elution, and the eluent containing harmful substances is collected for further treatment; finally, the filter mud after elution is dried.

[0031] Soluble harmful substances in filter mud can be removed by using water or specific solutions.

[0032] In the embodiment of the present invention, the specific operation of the heat treatment is: sending the filter mud into a dryer or a calcining furnace for treatment, and removing harmful substances in the filter mud by controlling the temperature and time of drying or calcining.

[0033] The content of harmful substances in filter mud can be reduced by drying or calcining.

[0034] The method of using sugar mill filter mud to improve soil and increase sugar beet yield and quality effectively reduces the content of harmful substances in the filter mud by sampling and collecting the sugar mill filter mud and through chemical stabilization, biological stabilization, solidification stabilization, leaching and heat treatment. Using sugar mill filter mud to improve soil helps to improve soil fertility and sugar beet yield and quality.

[0035] The method of using sugar factory filter mud to improve soil and increase sugar beet yield and quality realizes resource utilization of waste and reduces negative impact on the environment by using the treated filter mud to improve soil.

[0036] The method of improving soil and increasing the yield and quality of sugar beets by using sugar factory filter mud comprises the following steps: spreading filter mud A evenly on the surface of soil A by deep plowing and mixing, and then deep plowing and fully mixing the filter mud to achieve the effect of improving the soil; applying filter mud B as base fertilizer to soil B by layered application, and then covering it with a layer of fine soil to achieve the effect of improving the soil. By comparing the yield and quality data of sugar beets grown in soils improved by the two different improvement methods, it can be seen that the yield and quality of sugar beets produced by the soil improvement method of deep plowing and mixing is better.

[0037] Referring to the average yield of sugar beet per unit area in 2023 of 56,187 kg / hectare, 1 hectare is equal to 10,000 square meters, so 0.01 hectare is equal to 10 square meters, calculated by the following formula: (56187÷10000)×10, the result is: 56.187, then convert kilograms to catties, get: 56.187×2=112.374; According to the above calculations, when beets are grown on unimproved soil, approximately 112.374 kilograms of beets can be produced per 10 square meters of land.
