INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a method for manufacturing a plant nutrient solution, and more particularly to a plant nutrient solution which utilizes recycled kitchen waste and hydrophobic water as raw materials without sterilization process. The method. [Prior Art] In recent years, due to the relationship between economic development and eating habits, the amount of food 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. For these harmless organic wastes with rich nutrients, if these organic wastes with recycling value can be classified from general waste, they will be re-populated by appropriate methods. Not only can the amount of garbage be reduced, but also the purpose of resource reuse. " Disposal of waste from food waste and fruit and vegetable market in a composting manner is currently a more viable method. 'However, kitchen waste compost products tend to contain higher salinity and oil, which has doubts about the adverse effects on the soil; in addition, the moisture content of the kitchen waste is higher. 'The dry sub-materials must be added to adjust the moisture content to the appropriate range. 'This will increase the cost of (four) materials, the arbitrarily composted by the compost, and the mosquitoes and mosquitoes, etc., and the secondary pollution of environmental sanitation. Difficulties in the development of food waste include: (1) More than 75% of recycled kitchens still rely on the nutrition as the main source of back-to-back, labor "m pipelines" but the kitchen waste pigs are not accepted by the agricultural institutions. 2) The method of composting the kitchen waste, (4) facing the 1358402 battle of the control of the odor control, the long time of decomposing and the market access of the compost product. (3) At present, only the kitchen waste after the water filtration is recovered, as for the drowning And the large amount of effluent water generated during the composting process is still unable to be properly disposed, which may cause secondary environmental pollution. [The invention] Therefore, the present invention provides a method for manufacturing a plant nutrient solution, which is used for The invention further improves the process of regenerating the water content of the kitchen waste, and provides another option for the recycling of the kitchen waste. According to the above object of the present invention, a method for manufacturing the plant nutrient solution is proposed, which comprises A good gas culture to make the strain of the wood climbing strain TCT3〇1 suspension! 'Re.g-f machine material into the strain _ release float to form an initial battalion 丞 two and use this shovel to start a nutrient solution for a sputum Sputum fertilizer process To the hot stage of pregnancy - the original thing can be recovered for recycling (from the recovery of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The purpose of the invention is to achieve the purpose of resource utilization. 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/N rati〇) of less than 2〇, and is applied to the seed. The germination rate test results are higher than the sputum standard of 8〇%, and the application to the agricultural land can avoid the occurrence of environmental pollution and the harm of human health'. It is of great help to organic ecological agriculture. The invention utilizes kitchen waste and kitchen waste to produce The decomposing compost made from drowning and kitchen waste does not require degreasing and sterilization process for the production of plant nutrient solution, which not only simplifies the process but also completely recycles the kitchen waste and drowning water 100%. The nutrient solution has high fat content, is safe in nature and promotes 7 1358402. The plant has good growth effect. It has the value of replacing chemical fertilizers and pesticides. [Embodiment] At present, the liquid fertilizer method is prepared by high temperature sterilization and oil content. The less fermented compost is prepared as a raw material, and the present invention proposes that the plant nutrient solution prepared by recycling the kitchen waste and the drowning water is made into a safe and effective liquid fertilizer by the biotechnological method, and does not need to be subjected to a sterilization process, and can be simultaneously utilized. Recycling the kitchen waste and drowning water, the goal of truly achieving zero waste of 100% of the kitchen waste resources. Please refer to FIG. 1 , which illustrates a flow chart of a method for manufacturing a plant nutrient solution according to an embodiment of the present invention. As shown, a strain suspension of a new type of Trichoderma (strain name TCT301; Taibu District Agricultural Improvement Field) was prepared. The strain suspension contained an effective amount of Trichoderma TCT301, a nutrient source and degassed water. Complete fungi, its mycelial growth rate is faster than other fungi, and it is highly resistant to stress, and it can grow well under acidic conditions (pH is about pH 3.5~4.5); other pathogens (such as Fecal E. coli will be killed, which will ensure that the plant nutrient solution produced will not contain pathogenic bacteria; therefore, Trichoderma is selected as the main bacteria in the production of plant nutrient solution. . The dechlorination water is used to prevent the residual chlorine in the tap water from affecting the growth of the strain. The nutrient source is 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 suspension of the strain is mainly prepared by inoculating the Trichoderma strain TCT3〇1 in the dechlorinated water, giving a suitable carbon source to form a culture medium, and cultivating the Trichoderma to a rapid growth period under the condition of good gas 8 Trichoderma becomes the dominant species in the fermentation of plant nutrient solution. 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 mixture, and a composted compost mixture. 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. The composting compost can be used for the composting process of the above-mentioned kitchen waste after low temperature (30~4〇°C), medium temperature (45~60°C), high temperature (above 70°C) and rewarming (below 40°C). Got it. According to an embodiment of the present invention, the kitchen waste mixture used is crushed by a crusher to a particle size of less than 1 cm, and added with dechlorinated water to make the ratio of the kitchen waste to the dechlorinated water is about 1: 5 to 1: 1 between 〇. According to another embodiment of the present invention, the fermented compost mixture is used to add degassed water to the decomposed compost made from the temple, and the ratio of the decomposed compost to the degassed water is about 1:5, if a higher concentration is to be produced. When the plant nutrient solution is used, the addition ratio of the dechlorinated water can be reduced as appropriate. According to still another embodiment of the present invention, the hydrophobic water used can be a natural leaking liquid after the kitchen rest is placed, and the water for cleaning the kitchen waste recycling drum is mixed with a ratio of 1358402 of 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.

The highest L is carried out according to the aerobic liquid fertilization procedure of the present invention, and the woody fungus becomes the dominant species. On the 7th day, the number of pathogenic bacteria detected has been greatly reduced, 'the method of applying the invention is not required to pass. The high temperature sterilization procedure 'the pathogenic bacteria contained therein can be killed. Compared with the traditional production of liquid fertilizer, the raw material (composting) must be sterilized by high temperature to remove pathogenic bacteria. The present invention provides a simpler method. Making safe and effective plant nutrient solution Simplified process advantages. 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 composted compost mixture can be made of nitrogen %, phosphorus %, potassium %, carbon/nitrogen ratio, seed germination rate and grease removal rate. Other properties to analyze. The plant nutrient solution of different raw material sources 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 a minute of aeration. Mode culture makes it the dominant species. Three days later, the organic material (kitchen mixture, drowning or decomposed compost mixture) was added to the acid fermentation tank to give an aerobic liquid fertilizer program to + n 1358402. Among them, the kitchen waste mixture is 8 〇 kg of 仏 之 less than 1 part of the kitchen waste (evenly distributed fruit and fish) plus (10) liters of dechlorinated water; the compost compost mixture is 4 〇 kg of composted compost plus 16G a pound of dechlorinated water; or (10) 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 rati.) 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 soil-fertilizer should be less than 20. If the carbon-nitrogen ratio is too high, it will cause effective nutrient reduction in the soil, especially the nitrogen component, which will hinder 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 soluble salt base and produce soil reducing property, which will affect crop growth. Figure 2 shows the results of the determination of carbon to nitrogen ratio of plant nutrient solution made from kitchen waste, drowning water and cooked compost. The carbon-nitrogen ratio was determined according to the method for detecting the content of carbon, hydrogen, sulfur, oxygen, and nitrogen in the waste of niea R409.21C, which was determined by a halogen analyzer method, and analyzed using an elemental analyzer (Vari〇 EL m type). The results of the test showed that the initial carbon-nitrogen ratios of the plant nutrient solution prepared by the kitchen waste, the drowning water and the compost compost were 32.75, 26.17 and 19.46, but the liquid fertilizer process showed a downward trend; the 40th day The C/N ratios were 16.34, 15.21 and 12.21, respectively, and then showed a steady trend. 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 adversely affect the growth of the crop 12 1358402. 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 the proportion of the cooked food (meat and fish) is increased by appropriately distributing the raw material before the plant nutrient solution is started. The elemental content (for example, Np, K) of the animal amino acid or the canned mineral J plant nutrient solution directly added to the finished plant nutrient solution can be adjusted. In addition, the present invention utilizes the kitchen waste as the starting material, or the plant nutrient solution produced by the water or the compost compost produced by the kitchen waste, because the source is complicated and the oil content is more important than whether the oil wax contained therein has a bad effect on the soil _ The problem of human/losing wood should also take into account the effect of oil content on the mouth quality of plant nutrient solution. When the oil in the plant nutrient solution cannot be properly eliminated, such as application to crops, the oil film will be coated on the leaf surface, making the crop unable to customize photosynthesis and wilting. Therefore, the process of making a plant nutrient solution must ensure that the oil components are separated or decomposed. Figure 3 shows the results of the determination of the oil removal rate of the plant nutrient solution made from kitchen waste, drowning water and cooked compost. The determination of fats and oils was carried out according to the method of detecting the weight of water in Niia W506.21B - extraction gravimetric analysis. The results of the measurement showed that the initial oil content of the plant nutrient solution of kitchen waste and drowning water was 1654〇 and 836〇mg/liter (mg/L) respectively, and the initial oil content of the plant nutrient solution prepared by the compost compost was 32〇mg/ L. The oil content of the plant nutrient solution prepared by the kitchen waste decreased to 655〇mg/L on the 45th day, 60% of the oil content was removed, and the oil content decreased to 4950 mg/L on the 7th day, and the oil removal rate was 7〇%. The oil content of the nutrient solution of the plant 13 made from drowning water decreased to 3300 mg/L on the 25th day, the grease removal rate was 61%, and the oil content decreased to 2丨9〇mg/L on the 7th day, the oil The removal rate was 74%. The initial nutrient content of the plant nutrient solution prepared from the composted compost was 320 mg/L ' until the fat content decreased to 75 mg/L on the 70th day, and the grease removal rate was 77%. Therefore, the liquid fertilizer technology of the present invention can degrade the oil in the raw material, so the initial nutrient solution does not need to go through the oil removal step, and the liquid fertilizer process can be directly used to produce a good quality plant nutrient solution, which has a simplified process. The advantages. In addition, the plant nutrient solution prepared by using the kitchen waste, the drowning water and the mature compost for the crop seed germination rate test shows that the germination rate of the seeds of the kitchen waste and the drowning water is 93%, and the mature compost is 95%, which is in line with the literature suggestion. Should be greater than 80% of the maturity standards, such as application to agricultural land can have the potential value of replacing chemical fertilizers and pesticides.
