Description

200906763 IX. Description of the invention: [Technical field of invention] The present invention relates to a method for producing a plant nutrient solution, and particularly relates to a plant nutrient which utilizes recycled kitchen waste and hydrophobic water as raw materials without sterilization process. The method of liquid. [Prior Art] In recent years, due to the relationship between economic development and eating habits, the amount of kitchen waste produced by ordinary households accounts for about 20 to 30% of the amount of household waste. At present, the treatment of organic waste has been paid more and more attention. If these organic wastes with rich nutrients are classified, the organic wastes with recycling value can be classified from general waste and reused by appropriate methods. Not only can the amount of garbage be reduced, but the purpose of resource reuse can be achieved. It is currently a more viable method to treat waste from kitchen waste and fruit and vegetable market in a composting manner. However, kitchen waste compost products are prone to contain high salinity and oil, which may have adverse effects on the soil; in addition, the 3 water rate of the kitchen waste is higher. 'Dry sub-materials must be added to adjust the water content to the appropriate range. 'This will increase the cost of the addition of sub-materials' and requires a large-scale composting site, and the odor generated by the shaft and mosquito nets are also prone to secondary pollution problems of environmental sanitation. At present, the difficulties in the recycling of kitchen waste include: (1) More than 75% of the recycled kitchen waste is the main resource pipeline, but the kitchen waste pig is not accepted by the agricultural administration. (Chengfu composting treatment method still faces the problem of process control, long time of decomposing and market access of compost products, etc.) (7) At present, only the water is recovered, and in the drowning and composting The large amount of oozing water generated in the process cannot be properly disposed, and there is a problem of secondary environmental pollution.
Method, dyeing method Therefore, the present invention provides a method for manufacturing a plant nutrient solution to improve the process of regenerating the waste water, which is easy to produce secondary environmental pollution, and to provide another option for the recycling of the kitchen waste. According to the above object of the present invention, it is proposed that the production of the plant nutrient solution comprises the "suspension" of the Trichoderma strain TCT3G1 produced by aerobic culture.
The liquid, and then the organic material is added to the suspension of the human species to form an initial nutrient solution, and an aerobic liquid fertilizer process is performed to the maturity stage by using the initial nutrient solution. Among them, the organic raw materials can be recycled kitchen waste, the water produced by the recovery of Yuyu and the composted compost formed by the recycled kitchen waste; thus, the kitchen waste and the drowning water can be completely recovered to achieve the purpose of recycling the kitchen waste. The plant nutrient solution prepared by the method of the embodiment of the invention has a grease removal rate of more than 70%, a carbon to nitrogen ratio (c/Nrati〇) of less than 2〇, and the application rate of the seed germination rate is higher than 8〇%. The standard of maturity, applied to agricultural land can avoid the occurrence of environmental pollution and the harm of human health, which is of great help to organic ecological agriculture. The invention utilizes the waste water produced by the kitchen waste, the waste water generated by the kitchen waste and the fermented compost made of the kitchen waste to prepare the plant nutrient solution without going through the oil removal and sterilization process, which not only simplifies the process, but also can waste the kitchen waste and the water. 〇% is completely recycled and reused; in addition, the plant nutrient solution of the invention has high fertilizer content, safe nature and promotes the growth effect of the plant of 200906763, and has the value of replacing chemical fertilizers and pesticides. [Embodiment] At present, the liquid fertilizer method is prepared by using high temperature sterilization and decomposing compost with less oil content as raw materials, and the present invention proposes a plant nutrient solution prepared by using the residual water and the hydrophobic water, which is manufactured by a biotechnological method. Cheng = Fully effective liquid fertilizer, without the need of a sterilization process, and at the same time: Recycling the grinding and drowning, truly achieve the goal of 100% of the total waste of the kitchen resources. * Please refer to Fig. 1, which illustrates a flow chart of a method for preparing a nutrient solution according to an embodiment of the present invention. As shown in step 110~, a suspension of the strain of a new type of Phytophthora (strain name TCT301, Taichung District Agricultural Improvement Field) was prepared. The strain suspension contains an effective amount of Trichoderma TCT3〇1, a nutrient source and degassed water. Trichoderma belongs to the class of incomplete fungi. Its mycelial growth rate is faster than other fungi, and it is highly resistant to stress. It can grow well under acidic conditions (acidity is about pH 3.5~4.5) And other pathogenic bacteria (such as E. coli) will be killed, so as to ensure that the plant nutrient solution produced does not contain pathogenic g; therefore, Trichoderma is selected as the main strain when making plant nutrient solution. . The dechlorination water is to prevent the residual chlorine of the tap water from affecting the growth of the strain. The 3 sources are mainly used to supply the carbon source needed for the growth of Trichoderma, and the number of microorganisms can be increased to achieve the effect of controlling pests and diseases. The preparation of the #bacteria suspension was mainly carried out by inoculating the Trichoderma strain TCT3qi in dechlorinated water to give appropriate carbon source to form the culture medium, and cultivating the Trichoderma to the rapid growth period under the condition of good air 200906763 to make Trichoderma It becomes the dominant species when the plant nutrient solution is fermented. According to an embodiment of the present invention, the spores or hyphae of Trichoderma TCT301 can be used for inoculation, and the added nutrient source can be molasses or brown sugar. Aerobic culture can be assisted by an aeration device, which supplies gas at a rate of 10 to 15 minutes per hour to promote bacterial growth. In addition, since the microbial fermentation produces saponin substances, an appropriate amount of antifoaming agent can be added to the initial nutrient solution to avoid the problem of foaming. As shown in step 120, the organic material is mixed with the bacterial suspension to form an initial nutrient solution. The organic material is selected from the group consisting of a kitchen waste mixture, a hydrophobic water, and a mixture of decomposed i. The food used may contain raw food and cooked food. The ratio of raw food to cooked food is about 1: 1~1: 1 5 . The water is the water that naturally leaks after a period of time, or the water in the kitchen waste bin. Composting composting can be a composting procedure for the above-mentioned kitchen waste after low temperature (3〇~4〇C), medium temperature (45~60 C), high temperature (above 7〇°C) and rewarming (below 4〇°c) Production income. According to one embodiment of the invention, the kitchen waste mixture used is broken. The machine pulverizes the kitchen waste to a particle size of less than 1 cm, and adds dechlorinated water to mix, so that the ratio of the kitchen waste to the dechlorinated water is about 1: 5 to 1: 1 。. According to another embodiment of the present invention, the fermented compost mixture is added to the decomposed compost made from the kitchen waste to add dechlorinated water, and the ratio of the decomposed compost to the dechlorinated water is about 1:5, if a higher concentration is to be produced. When the plant nutrient solution is used, the proportion of degassing water added can be reduced. According to still another embodiment of the present invention, the water used can be a liquid that naturally leaks after the kitchen is left to stand, and the water for cleaning the waste recovery tank is mixed, and the mixing ratio 200906763 is about 4:1. As shown in step 130, the initial nutrient solution is subjected to an aerobic liquid fertilizer process, and the aerobic liquid fertilizer process is aerated by means of an aeration device that injects gas from the surface of the initial nutrient solution. According to an embodiment of the present invention, the aerobic liquid fertilizer process has a time of about 40 to 60 days to reach the stage of decomposing, and the pH value, oxidation-reduction potential (ORP), and electrical conductivity (EC) of the initial nutrient solution. The parameters such as carbon/nitrogen ratio (C/N) and volatile organic compounds (VOCs) are stable after 40 days to 60 days. According to an embodiment of the present invention, when the aerobic liquid fertilizer process is performed, the pH value of the initial nutrient solution can be controlled between 4.0 and 7.0; within 10 days after the start of aeration, the pH is lowered to a weakly acidic to acidic range (about pH). Between 3.2 and 4.5), in the pH range, Trichoderma can still grow well, while other pathogenic bacteria can be effectively killed, without high temperature sterilization, the plant nutrient solution produced will not have the doubts of pathogenic bacteria. . Please refer to Table 1 for the change in the number of pathogens (for example, fecal E. coli) during the aerobic liquid fertilizer process. Table 1. Changes in the number of pathogenic bacteria in aerobic liquid fertilization procedures. Plant nutrient solution production materials, kitchen waste, water, mature compost days, feces, feces, feces, PH, E. coli population, number of E. coli, number of E. coli groups (MPN/100mL ) (MPN/100mL) (MPN/100mL) 0 4.72 1100 4.01 460 6.81 150 7 4.06 <3 3.25 <3 4.19 <3 40 4.42 <3 3.85 <3 5.20 <3 10 200906763
As can be seen from Table 1, since the source of Weiyu and Lishui is more complex than that of composted compost, the number of bacteria in the beginning of grinding and drowning is significantly higher than that of composting compost, especially in kitchen waste. However, with the aerobic liquid fertilizer program of the present invention, 'Trichoderma becomes the dominant species, the number of pathogenic bacteria detected on the 7th day has been greatly reduced, demonstrating that the method of the present invention is applied without going through high «The bacteria program, the pathogenic bacteria contained therein can be killed, compared to the traditional method." The raw material (fertilized compost) must be subjected to high temperature sterilization to remove pathogenic bacteria, and the present invention provides a simpler method. The method of making safe and effective plant nutrient solution has the advantage of simplifying the process. Since the kitchen waste contains many organic substances and nutrient sources, it is decomposed by microorganisms and dissolved in water, and then applied to crops. The effect of promoting plant growth, improving soil structure and controlling crop pests and diseases can be better than solid compost. According to the above embodiment of the present invention, the plant nutrient solution prepared by using the kitchen waste mixture, the hydrophobic water or the composting compost mixture can be analyzed for the quality of phosphorus, potassium, carbon/nitrogen ratio, seed germination rate and grease removal rate. . The plant nutrient solution of different raw materials is prepared by placing 30 grams of Trichoderma (TCT301), 10 liters of molasses and 4 liters of dechlorinated water into a 300 liter fermentation tank for 1 hour per hour. The culture in minutes is made to be the dominant species. After three days, organic materials (kitchen mixture, drowning or decomposed compost mixture) were added to the fermenting tank to give aeration 11 200906763 for aerobic liquid fertilizer. The 'kitchen waste mixture is 80 kilograms of kitchen waste with a particle size of less than 1 cm (evenly distributed with fruits and fish) plus liters of dechlorinated water; the compost compost mixture is 4 kg of decomposed compost plus 160 kg. Chlorine water; or 22 liters of water from the kitchen waste water tank. Carbon is a source of microbial energy and synthetic cellular tissue, and nitrogen is an important source of protein synthesis, both of which are indispensable nutrients for microbes. A lower carbon to nitrogen ratio (C/N ratio) releases ammonia and impedes microbial activity, while a higher carbon to nitrogen ratio makes nitrogen a limiting factor for crop growth. The carbon to nitrogen ratio applied to the fertilizer in the soil should be less than 20. If the carbon to nitrogen ratio is too high, the effective nutrient reduction in the soil will be caused, especially the nitrogen component has the greatest influence and hinders the growth of the crop. When the carbon to nitrogen ratio is too low, it can be directly applied to the soil, which will release a large amount of soluble salt base and produce soil reducing property, which will affect crop growth. The second figure shows the results of the determination of the carbon-nitrogen ratio of the plant nutrient solution prepared by Lifu, Yushui and cooked compost. The carbon-nitrogen ratio was determined by the elemental analyzer method for the determination of carbon, hydrogen, sulfur, oxygen, and nitrogen in the waste of niea R409.21C, and analyzed using an elemental analyzer (VaH〇 EL m type).
The results of the measurement show that the initial carbon-nitrogen ratios of the plant nutrient solution prepared by the kitchen waste, the water and the compost compost are 32.75, 26.17 and 19.46, but the liquid fertilizer process has a decreasing trend; the 40th day C /N is a stable trend after 16.34, 15.21 and 12.2. Therefore, the plant nutrient solution prepared by the method of the present invention all meets the recommendation that the C/N ratio is less than 20, and if applied to the soil, it will not have an adverse effect on crop growth. (4) According to an embodiment of the present invention, the element content of the plant nutrient solution can be adjusted according to different plant growth requirements, and before the plant nutrient solution is started, the raw materials are appropriately distributed, and the proportion of cooked food (meat and fish (6) is increased, or The animal amino acid (4) mineral powder is directly added to the finished plant nutrient solution, and the element content of the finished plant nutrient solution (for example, Ν, ρ, κ) can be adjusted. In addition, the invention utilizes the kitchen waste as the starting material or the kitchen waste. The plant nutrient solution produced by the drowning or composting compost is complicated because of its complicated source and high oil content. It is necessary to consider whether the oil contained in it has adverse effects on the soil and secondary pollution, and also consider the oil content. The effect of the quality of plant nutrient solution. When the oil in the plant nutrient solution can not be properly eliminated, such as application to the crop, the oil film will be coated on the leaf surface, making the crop unable to photosynthesis 19. Therefore, the plant nutrient solution The production process must ensure that the oil components are separated or decomposed. Figure 3 is the use of kitchen waste, water and compost. The determination result of the oily removal rate of the prepared plant nutrient solution is determined according to the W506.21B water towel oil seam test method-extraction gravimetric analysis. The results of the test show that the kitchen nutrient solution is produced by the kitchen waste and the drowning water. The initial oil content is 16540 and 836〇mg/liter (mg/L), and the initial oil content of the plant nutrient solution prepared by the compost compost is 32〇mg/L. Among them, the oil content of the plant nutrient solution made by the kitchen waste is On the 45th day, it dropped to 655〇mg/L, 60% of the oil content was removed, and then the oil content decreased to 495〇mg/L on the 7th day, and the oil removal rate was 7〇%. The plant made with the water 13 200906763 The oil content of the nutrient solution decreased to 33〇〇mg/L on the 25th day, and the oil removal rate was 61%. The oil content decreased to 2i9〇mg/L on the 7th day, and the grease removal rate was 74%. The initial oil content of the plant nutrient solution prepared by the compost compost is 320 mg/L, and the oil content is reduced to 75 mg/L on the 7th day, and the grease removal rate is 77%. It can also be said that the liquid fertilizer technology of the present invention can be Degradation of the oil in the raw material, so at the beginning The nutrient solution does not need to go through the oil removal step, and can directly perform the liquid fertilizer process to produce a good quality plant nutrient solution, which has the advantages of simplified process. In addition, the plant nutrient solution made by using the kitchen waste, drowning water and cooked compost for the crop The germination rate test showed that the germination rate of the seeds of kitchen waste and drowning was 93%, and that of mature compost was 95%, which was in line with the maturity standard of more than 80% recommended by the literature. If applied to agricultural land, it could replace chemical fertilizers and pesticides. The present invention has been disclosed in the above-described embodiments, and is not intended to limit the invention, and the invention may be practiced as various changes and modifications without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
