Description

  The present invention relates to a method for producing compost in a short period of time by fermenting pruned branches and leaves.

  A large number of pruned branches and leaves are produced by pruning trees in parks and streets and garden trees in the home, and the processing method has become a problem. Many parks and camphor trees are planted in the park, and there are many ginkgo, lily, cherry, zelkova, and maple trees in the roadside trees. In addition, since tree pruning is concentrated in summer (July to August) and winter (11 to December), the amount of pruned branches and leaves is large during this period. In the past, many of the pruned branches and leaves have been disposed of by incineration or landfill as waste materials. However, incineration aids the generation of carbon dioxide. In addition, in landfill disposal, woody organic matter in the soil becomes a hotbed for the generation of soil-borne infectious diseases, which can eventually damage plants.

  Regarding the disposal of pruned branches and leaves, effective use of pruned branches and leaves is being considered in various directions from the viewpoint of environmental protection and recycling, rather than the disposal by incineration and landfilling in the past. As one of them, it has been proposed to ferment pruned branches and leaves to compost.

  As a method for fermenting pruned branches and composting, generally, a method of making pruned branches and leaves into fine chips is known. First, pruned branches and leaves are made into chips of 2 to 3 cm using a crusher. The chips are piled up to a height of about 2 m. Water is added to this so that the water content becomes 60%. Deposition is usually performed for 6 months or more. During this time, stirring or turning over is performed about once a month, and if water is low, water is added. The compost made in this process has a dry matter content of 1.5% nitrogen, 0.3% phosphoric acid, and 0.5% potassium.

  Furthermore, as shown in Patent Documents 1 and 2, there is a forced fermentation treatment method that promotes fermentation decomposition after appropriately adjusting temperature and moisture conditions in a semi-sealed tank in order to increase the treatment efficiency of fermentation. Proposed.

  However, the method of fermenting pruned branches and composting has the following problems. First, since the pruned branches and leaves contain a large amount of cellulose, lignin and the like that are hardly degradable, composting of the pruned branches and leaves requires a long period of time. Usually, composting involves primary fermentation in which microorganisms that decompose sugars play an active role, secondary fermentation in which microorganisms that decompose proteins and amino acids play an active role, and finally microorganisms that decompose difficult-to-decompose cellulose and lignin. After three stages of active curing fermentation, composting usually requires a long period of about 6 months to 1 year. In addition, the forced fermentation treatment methods proposed in Patent Documents 1 and 2 also require a minimum of 60 days to 90 days. For businesses dealing with compost, the long-term composting is a serious management issue.

  Second, in order to promote fermentation, there is a problem in selecting and using livestock manure as an additive. Livestock may be given antibiotics, growth-promoting hormones, and other drugs along with the formula feed, so the drugs may remain in manure. Compost made using such manure as an additive for fermentation has a safety problem.

  Thirdly, in the rapid forced fermentation treatment methods as described in Patent Documents 1 and 2, it is necessary to carry out the deposition processing object by manual work or mechanical work every other day or several days, which takes time and increases the cost. Connected. In the processing method shown in Patent Document 2, an increase in size of the equipment is required.

Japanese Patent No. 3301578 Japanese Patent No. 2655298

  In view of the above problems, an object of the present invention is to provide a method for producing compost that ferments pruned branches and composts in a short period of time without using livestock manure as an additive.

A second nutrient source spraying step in which the nutrient source is again sprayed on the deposits that have finished the first fermentation step; a second stirring step in which the sediment that has been sprayed again with the nutrient sources is stirred; The deposit is again deposited in the open atmosphere and the temperature And a second fermentation step for fermenting for a predetermined period of time, a compost production method comprising: pre-fermentation for pre-fermenting molasses to produce fermented molasses as a nutrient source; and first fermentation The three-stage fermentation process with the second fermentation is performed. In addition, the agricultural product residue processed material may be an onion skin.

  Fermented molasses may be fermented by adding either coniferous or hardwood humus to the molasses.

  In the first fermentation step, the temperature is adjusted to 70 to 75 ° C. for 8 to 10 days and fermented, and then the fermented for 10 to 12 days. Moreover, the 2nd fermentation process is good to carry out the curing fermentation for 10 to 12 days, after adjusting the temperature to 70 to 75 degreeC for 8 to 10 days and fermenting similarly to 1st fermentation.

  The pruned branch chip material is preferably formed so as to be formed into a substantially cylindrical body having a diameter of 30 mm or less. When the pruned branches and leaves are crushed, the pruned branches and leaves can be processed into a substantially cylindrical pruned branch and chip chip material by making the screen holes of the crusher used for crushing into a substantially circular shape.

  In the first stirring step, the deposit on which the nutrient source is dispersed may simply be turned upside down, and in the second stirring step, the deposit on which the nutrient source has been dispersed again may be transferred to a predetermined place.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same number is attached | subjected to the same part, and the overlapping description is abbreviate | omitted. It should also be noted that the drawings may be exaggerated to understand the present invention and are not necessarily shown to scale. The present invention is not limited to the embodiment shown below.

  Example 1 will be described in detail with reference to the drawings. Among these, the 1st characteristic of the manufacturing method of the compost of this invention is that the shape of the pruned branch leaf chip material 1 which processes a pruned branch leaf into a chip | tip contains a substantially cylindrical body. The second feature is that, when the nutrient source 2 is produced, pre-fermentation for producing the fermented molasses 4 in which the molasses 5 is previously fermented with the coniferous or hardwood humus 7, the first fermentation, and the second fermentation By performing the three-stage fermentation process, the treatment period is shortened and the degree of maturity of the compost is improved.

  Please refer to FIG. FIG. 1 is a diagram showing a composting process of the present invention. First, using a crusher, the pruned branches and leaves are made into a fine chip shape (pruned branch and chip chips 1) of approximately 30 mm (S0101). Next, the pruned branch chip material 1 is deposited in a mountain shape on the fermentation compost yard to form a deposit 3 (S0102). Subsequently, the nutrient source 2 is sprayed on the deposited body 3 of the pruned branch leaf chip material 1 (S0103). The nutrient source 2 is preferably a mixture of fermented molasses 4 and water 6 as described in detail below. The application amount of the nutrient source 2 is preferably 20 to 50 liters / m 2 per time. After depositing or spreading the nutrient source 2, the deposit 3 may be stirred or turned over once (S0104). Note that the first stirring may be a step of simply turning the deposit 3 on which the nutrient source 2 is dispersed upside down. Thereafter, the deposit 3 is fermented for approximately 20 days (S0105). As will be described later, the temperature of the deposit 3 reaches 70 ° C. by fermentation heat in 3 days from the start of composting, and is maintained at 70 ° C. to 75 ° C. for about 6 days thereafter. This heat of fermentation kills pathogenic bacteria, parasite eggs, weed seeds, and the like. Thereafter, the temperature of the deposit 3 gradually decreases and enters curing fermentation, and after 20 days from the start of composting, the temperature decreases to the atmospheric temperature.

  In the composting process, the above-described nutrient source application (S0103), agitation (S0104), and fermentation (S0105) are repeated twice. That is, it passes through the composting process of 2nd nutrient distribution (S0106), 2nd stirring (S0107), and 2nd fermentation (S0108). The second agitation may be a step of simply moving the deposited body 3 sprayed with the nutrient source 2 again to a predetermined location. In the final step of the composting step, clean sorting is performed to remove foreign substances and the particle size is adjusted (S0109). Aged compost (YES) and immature compost (NO) are separated in the particle size adjustment step. The matured compost is packaged as a finished product, and the immature compost enters the second nutrient source spray (S0106), second agitation (S0107), and second fermentation (S0108) again, and then becomes matured compost. .

  Please refer to FIG. FIG. 2 is a diagram schematically illustrating the shape of the pruned branch chip material 1 of the present invention according to the first embodiment. (A), (b), (c) shows the shape of the pruned branch chip material 1 exemplarily. As shown in FIG. 2 (a), the shape of the pruned branch chip material 1 is preferably a substantially cylindrical body 1a. This is to increase the area to which the nutrient source 2 adheres. Moreover, the size of the pruned branch chip material 1 should just be 30 mm or less in diameter, for example. As shown in FIGS. 2B and 2C, the substantially cylindrical bodies 1b and 1c do not have to be exact cylinders, and may be flat or irregular.

  Various methods are conceivable as methods for producing the pruned branch chip material 1 described above into a substantially cylindrical body. In Example 1, it produces using a crusher. Usually, since the eye holes of the screen of the crusher are rectangular, the pruned branch chip material 1 crushed through the eye holes of the screen is often a square material. In the first embodiment, the pruned branch chip material 1 can be formed into a substantially cylindrical body by making the screen holes circular. However, the pruned branch chip material 1 may be formed into a substantially cylindrical body by a method other than the crusher.

  Please refer to FIG. FIG. 3 is a diagram illustrating a deposition state of the deposited body 3 of the pruned branch chip material 1 according to the first embodiment of the present invention. FIG. 3A shows a state in which the nutrient source 2 is sprayed on the deposit 3, and FIG. 3B shows a state in which the pruned branch chip material 1 is deposited. As shown in FIG. 3 (a), the deposition site is previously excavated from the ground 40 to 60 cm deep 1 m deep and spread with gravel. The deposition location is preferably a location where the squeezed water 10 can be drained. In Example 1, using the nebulizer 31, the nutrient source 2 is sprayed on the deposit 3 as shown by the arrow a. The spread nutrient source 2 soaks into the pruned branch leaf chip 1 contained in the sediment 3 and fermentation starts by the action of microorganisms. In the process of fermentation, the squeezed water 10 oozes out into the ground. The appearance of the squeezed water 10 in the ground is as shown by the arrow a. A pipe 50 for receiving the squeezed water 10 is laid, and the pipe 50 has numerous holes for receiving the squeezed juice 10. This squeezed juice 10 is stored in a tank (not shown), and the stored squeezed water 10 is sprayed on the sediment 3 together with the nutrient source 2 and reused.

  Next, refer to FIG. FIG. 3B schematically shows a part of the pruned branch chip material 1 constituting the pile 3 in a piled state. The diameter of the pruned branch chip material 1 is preferably 30 mm or less, includes a substantially cylindrical shape, and is deposited with the pruned branch chip material 1 having various sizes. The deposit 3 is preferably deposited to a height of about 2 m. It will also be understood that the end materials of the pruned branches and leaves are also deposited together, so that the air permeability is good and the dispersed nutrient source 2 is easily soaked into the deposit 3. For the activity of microorganisms, it is necessary to secure clearance and increase the contact rate with air. Composting uses the function of aerobic microorganisms, so the supply of oxygen is essential. Aerobic microorganisms break down organic matter using oxygen, generate heat of fermentation, and promote ripening and moisture evaporation. Therefore, the sedimentary structure of the sediment 3 improves the air permeability of the pruned branch leaf chip material 1 that is a compost raw material, thereby promoting the function of microorganisms and promoting efficient fermentation.

  Here, a method for producing the nutrient source 2 will be described. The nutrient source 2 mainly consists of fermented molasses 4 and water 6. First, the method of fermenting molasses 5 to fermented molasses 4 will be shown. The fermented molasses 4 is produced by fermenting the molasses 5 using microorganisms contained in the coniferous humus 7. The molasses 5 may be sugar or brown sugar in addition to sugarcane molasses, sugar beet molasses, refined molasses, hydrol, various fermentation waste liquids and residual sugars, high test molasses. Moreover, the humus 7 is not limited to a conifer, and may be a hardwood humus. Molasses 5 is put in a predetermined tank, and an appropriate amount of humus 7 is charged. Then, various microorganisms contained in the humus grow and ferment. This is called pre-fermentation, and the fermented molasses 5 is fermented molasses 4. The pre-fermentation may be about 1 day. The fermented molasses 4 includes various microorganisms that have grown. Next, 500 liters of water 6 and 34 liters of fermented molasses 4 are put into a tank of over 500 liters. Then, the nutrient source 2 is completed in a few days. Usually, it takes 3 days in summer and 4 days in winter to produce nutrient source 2. In addition, it is necessary to adjust sugar content by the temperature at the time of preparation. For example, when the temperature is 28 ° C. to 30 ° C., the sugar content is 16 degrees, and when the temperature is lower than 28 ° C., the sugar content is 20 degrees. In addition, although it is preferable to use the water 6 clustered, it is not limited.

  In the composting process, ammonia is generated, so composting is performed in an alkaline state. The pH is weakly alkaline of about 7 to 8, and the activity of the microorganism is maximized. Even if the composting raw material is weakly acidic, ammonia is produced when composting starts, so the pH gradually increases and the alkalinity is maintained. Composting works partly with anaerobic bacteria, but mostly decomposes organic matter into carbon dioxide and water by the action of aerobic bacteria. Low molecular weight sugars are available in most microorganisms. Starch is finally converted to glucose by a special kind of function among filamentous fungi and bacteria, and is degraded by other microorganisms. Proteins change from polypeptides to amino acids upon microbial hydrolysis. Amino acids are changed to ammonia, carbon dioxide, organic acids, alcohols, etc. by the action of bacteria and filamentous fungi, and other microorganisms are further decomposed. Composting is due to the activity of microorganisms, and for good composting, it is important to prepare an environment in which microorganisms can easily act. Usually, microorganisms that decompose and ferment sugar in primary fermentation work, microorganisms that decompose amino acids and proteins work in secondary fermentation, and microorganisms that decompose cellulose, lignin, etc. work sequentially in curing fermentation to complete compost .

  In the composting process of Example 1, when producing the nutrient source 2, pre-fermentation for producing the fermented molasses 4 in which the molasses 5 is previously fermented with the coniferous or hardwood humus 7, and the first fermentation process, A three-stage fermentation process with the second fermentation process is performed. When the fermented molasses 4 is produced, microorganisms contained in the humus 7, particularly microorganisms such as filamentous fungi and basidiomycetes, are growing, and the activities of these microorganisms are already high at the preliminary fermentation stage. In addition, by performing the fermentation process twice in the first fermentation process and the second fermentation process, the functions of microorganisms that decompose sugars and microorganisms that decompose amino acids and the like are simultaneously activated at high temperatures. Thus, it can be seen that the fermentation activity is promoted, and further, the decomposition promotes cellulose, lignin and the like by microorganisms such as the filamentous fungi and basidiomycetes that have been proliferated and activated in advance.

  Please refer to FIG. FIG. 4 is a graph showing a temperature transition in composting of the present invention according to Example 1. As shown in FIG. 4, the temperature of the deposit 3 reaches 60 ° C. by fermentation heat in 3 days from the start of composting, and the temperature rises to 70 ° C. to 75 ° C. and is maintained in 9 days from the start. This heat of fermentation kills pathogenic bacteria, parasite eggs, weed seeds, and the like. Thereafter, the temperature of the deposit 3 gradually decreases, and after 20 days from the start of composting, the temperature decreases to the atmospheric temperature.

表１における３回の計測結果によると、リグニンは、初日から１０日目と、２０日目から３０日目の高温下の条件で分解が遅く、１０日目から２０日目と、３０日目から４０日目に速く進んでいることがわかる。また、全体として、リグニンの分解は速く行われていることが理解されるであろう。 About the processed material of the deposit 3, the result measured about the transition of lignin content is shown below. The sulfuric acid method is used for the measurement of the lignin content, and the setting conditions are the temperature conditions and the required days as shown in FIG.

According to the measurement results of three times in Table 1, lignin is slow to decompose under conditions of high temperature from the first day to the 10th day and from the 20th day to the 30th day, from the 10th day to the 20th day, and from the 30th day. It can be seen that it is moving fast on the 40th day. Also, as a whole, it will be understood that the degradation of lignin is fast.

表２によれば、日本バーク堆肥協会品質基準との対比として、堆肥Ａの分析結果を示している。これによると、ｐＨは、７．０で基準内である。ＥＣは１．６０で基準内である。ＥＣ（電気伝導率）の高い堆肥は根痛みの原因になる。ＥＣとは、堆肥に含まれる養分の多少を測定するもので、乾燥した堆肥を１０倍量の水で抽出し、その液の２５℃で電気伝導率を測定し、ミリシーメンス（mS／cm）の単位でしめす。全窒素、全リン酸、全カリともに基準を超えている。また、全炭素率（Ｃ／Ｎ比）も２３で基準内となっている。堆肥の肥料効果は、炭素率（Ｃ／Ｎ比）の大小が目安となるが、ちなみに炭素比率の高い堆肥は肥料効果が小さく、炭素比率の低い堆肥は肥料効果が大きいといわれる。有機物の比率も基準を超えている。 Compost A composted in the above process is completed in about 40 days. Table 2 below shows the analysis results (Japan Fertilizer Testing Association).

According to Table 2, the analysis result of the compost A is shown as contrast with the quality standard of the Japan Bark Compost Association. According to this, the pH is within the standard at 7.0. EC is within 1.60 at 1.60. Compost with high EC (electrical conductivity) causes root pain. EC is a measure of the amount of nutrients contained in compost. Dry compost is extracted with 10 times the amount of water, the electrical conductivity of the solution is measured at 25 ° C, and millisiemens (mS / cm). Indicated in units of. Total nitrogen, total phosphoric acid, and total potassium all exceed the standards. Also, the total carbon ratio (C / N ratio) is within the standard at 23. The fertilizer effect of compost is based on the carbon ratio (C / N ratio). By the way, compost with a high carbon ratio has a small fertilizer effect, and compost with a low carbon ratio is said to have a large fertilizer effect. The ratio of organic substances also exceeds the standard.

  Next, Example 2 will be described in detail with reference to the drawings.

  FIG. 5 is a diagram showing another composting process of the present invention. As in Example 1, first, using a crusher, the pruned branches and leaves are made into a fine chip shape (pruned branch and chip chips 1) of approximately 30 mm (S0201). Next, the agricultural product residue processing material 8 is added to the pruned branch chip material 1 (S0202).

  Subsequently, a mixture of the pruned branch chip material 1 and the agricultural product residue processed material 8 is deposited in a mountain shape in the fermentation compost yard (S0203). In Example 2, the onion skin 9 is used for the agricultural product residue processing material 8, but it is not limited thereto. The onion hull 9 was used in the onion producing areas such as Awaji Island in Hyogo Prefecture, where a large amount of onion hull 9 has been discarded. By using compost, the onion hull 9 can be reused. Because.

  Subsequently, the nutrient source 2 is sprayed on the mixed material of the pruned branch leaf chip material 1 and the agricultural product residue processed material 8 (S0204). After spraying the nutrient source 2 or while spraying, the deposit 3 is stirred or turned over once (S0205). Thereafter, the deposit is fermented for approximately 20 days (S0206). The temperature of the deposit 3 reaches 70 ° C. by fermentation heat in 3 days from the start of composting, and is then maintained at 70 ° C. to 75 ° C. for about 6 days. Thereafter, the temperature of the deposit 3 gradually decreases, and after 20 days from the start of composting, the temperature decreases to the atmospheric temperature. As a general rule, the composting process repeats the above-described nutrient source application (S0204), agitation (S0205), and fermentation (S0206) processes twice. That is, it passes through the composting process of 2nd nutrient source dispersion | distribution (S0207), 2nd stirring (S0208), and 2nd fermentation (S0209). The second agitation may be a step of simply moving the deposited body 3 sprayed with the nutrient source 2 again to a predetermined location. When the temperature of the deposit 3 is lowered to the atmospheric temperature through the composting process described above, the compost B is completed. In the final step of the composting step, clean sorting is performed to remove foreign substances and the particle size is adjusted (S0210). Aged compost (YES) and immature compost (NO) are separated in the particle size adjustment step. The matured compost is packaged as a finished product, and the immature compost is re-entered in the steps of spraying nutrient sources (S0207), stirring (S0208), and fermentation (S0209), and then becoming matured compost.

表３によると、ｐＨは、８．６である。全窒素、全リン酸、全カリともに実施例１に係る製造方法で製造された堆肥Ａに比べると低い。また、全炭素率（Ｃ／Ｎ比）は１８である。なお、当該堆肥Ｂについては、陽イオン交換容量も分析しており、３７．８ｍｅ（乾物換算値：８５．７ｍｅ）と高い数値を示している。陽イオン交換容量（ＣＥＣ）は、土壌の粒子が静電気的に吸着できる陽イオンの量を示している。土壌を構成する物質のうち、粘土鉱物と土壌有機物にはＣＥＣがあり、陽イオンとして存在するアンモニア、カリウム、カルシウム、マグネシウムなどの養分が雨水によって洗い流されないように、土壌中に保持されている。このため、ＣＥＣが高くなると保肥力が高まり、土が肥沃になる。 Compost B made in this process is completed in about 40 days. Table 2 below shows the analysis results (Japan Fertilizer Testing Association).

According to Table 3, the pH is 8.6. Total nitrogen, total phosphoric acid, and total potash are all lower than compost A produced by the production method according to Example 1. The total carbon ratio (C / N ratio) is 18. In addition, about the said compost B, the cation exchange capacity | capacitance is also analyzed and the high numerical value is shown with 37.8me (dry matter conversion value: 85.7me). Cation exchange capacity (CEC) refers to the amount of cations that can be adsorbed electrostatically by soil particles. Among the substances that make up soil, clay minerals and soil organic matter have CEC, and are held in the soil so that nutrients such as ammonia, potassium, calcium, and magnesium that are present as cations are not washed away by rainwater. . For this reason, if CEC becomes high, fertilizer power will increase and soil will become fertile.

Table 4 below shows the test results of compost B conducted in the environment department of the Hyogo Prefectural Agriculture, Forestry and Fisheries Technology Center. The test was carried out using a takii seedling Komatsuna “Rakuten” as a test crop, and shows the results at each fertilizer application amount per 10a. According to this test result, the average stock weight by the fertilization of the compost B of the present invention was 9 times that in the case of no fertilizer and 135% compared to the case of fertilizing 10 kg of chemical fertilizer. For the application of compost B according to the present invention, no apparent failure was observed.

  As mentioned above, although preferred embodiment in the manufacturing method of the compost | manure which concerns on this invention has been illustrated and demonstrated, it will be understood that various changes are possible without departing from the technical scope of this invention.

  The method for producing compost of the present invention is a method for producing compost in a short period of time by fermenting pruned branches and leaves generated in large quantities from roadside trees and parks without incineration or landfilling. The compost produced by the method for producing compost of the present invention can be widely used for household use and business use as a safe organic soil improvement material.
