Description
Technical Field
The invention relates to the technical field of tobacco water pyrolysis preparation, in particular to a preparation method and application of straw-source tobacco water.
Background
Crop straws are a valuable renewable resource, and the main components are cellulose, hemicellulose and lignin. The annual production of the straws in China is about 8 hundred million tons, the comprehensive utilization rate of the straws reaches 86 percent, but more than 1 hundred million tons of straws are still discarded every year, and serious resource waste is caused.
The smoke water is prepared by dissolving smoke generated by burning/pyrolyzing plants in water. The tobacco water has complex components and contains more than 5000 compounds, wherein Karrikins (KARs for short) and cyanohydrin can effectively promote seed germination, and trimethylbutenolide (TMB for short) can inhibit seed germination. KARs are produced by combustion/pyrolysis of cellulose and hemicellulose, whereas combustion/pyrolysis of lignin can produce seed germination inhibiting substances. Due to different plant raw materials and preparation methods, the effects of the tobacco water from different sources are often different, and the application of the tobacco water is limited.
The pyrolysis parameters of the three components of cellulose, hemicellulose and lignin are different. The billionths study (2013) suggested that hemicellulose is the least thermally stable and begins to pyrolyze at about 220 ℃; the pyrolysis temperature range of the cellulose is narrow, the cellulose is decomposed at 300-375 ℃, and the temperature rise rate is lower than 2 ℃/min, so that the main pyrolysis interval of the cellulose pyrolysis can be moved down to 230-280 ℃; the lignin has the most complex structure and wider pyrolysis temperature, and decomposes at 500 ℃ under 250 ℃ and 420 ℃ under 310 ℃. Kilzer (1965) proposed that there are two competing routes for cellulose pyrolysis, and that low heating rates allow cellulose pyrolysis in the range of 200-. The difference of thermal decomposition parameters can be utilized to produce high-quality tobacco water by an accurate temperature control pyrolysis method.
Weeds are extremely harmful to agricultural production, and cause the yield of crops to be reduced by about 10 percent every year. Chemical control with herbicides as the core is the main means of weed control today, but it presents a serious environmental hazard. The difficulty in weed control is related to the complexity of a soil seed bank, a large number of seeds with various varieties are accumulated in soil for a long time, and the dormancy degrees of the seeds are different, so that the seedlings are scattered and are not beneficial to control (Qiang Sheng, 2010). The farmland weed seed bank is a dynamic system, and has input and output simultaneously, wherein the input is mainly based on mature weed fructification, and the output is mainly based on seed germination and death. When the input quantity is larger than the output quantity, the seed bank is enlarged, the harm of the weeds is increased, otherwise, the seed bank is reduced, and the harm is reduced. Under the condition of stable input, measures are taken to promote the germination of seeds in the soil seed bank, reduce the number of weed live seeds in the soil seed bank, reduce the weeding cost and reduce the environmental pollution, and have important economic and social values.
Seed treatment technology is widely applied in agricultural production. The seed treatment can improve the seed quality, improve the sowing quality, prevent and control seed-borne or soil-borne diseases, promote the seeds to germinate rapidly, ensure the seedlings to be tidy and robust, and reduce the dosage of the seeds, pesticides and fertilizers (Zhang Silent, etc., 2012). The seed treatment technology mainly comprises a chemical method, a physical method, a biological method and the like. Chemical treatment is a commonly used seed treatment method at present, mainly referring to the treatment of seeds with insecticides, bactericides, plant growth regulators and the like (Zhang et al, 2012). The study of Lishifei et al (2014) found that GA3The treatment with salicylic acid can improve the seed activity of bupleurum chinense seeds, promote the germination of the seeds, improve the emergence rate, improve the root activity and ensure higher seedling survival rate. The study of He Li et al (2018) found that different concentrations of GA were used3The tomato seeds are treated, so that the plant height, stem thickness and fresh weight of overground parts of seedlings can be improved, and the growth of the seedlings is promoted.
Because the substances promoting the seed germination in the tobacco water are generated by burning/pyrolyzing cellulose and hemicellulose, the lignin can generate inhibiting substances by burning/pyrolyzing the lignin, and the crop straws all contain three components of the cellulose, the hemicellulose and the lignin, the tobacco water produced by burning the straws has poor and unstable effect at present, and the application of the straw source tobacco water in the agricultural field is limited.

Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
As described in the background section, straw-derived flue gas produced from straw as a raw material has problems of poor and unstable performance because seed germination-promoting substances (e.g., KARs) in flue gas are generated by combustion/pyrolysis of cellulose and hemicellulose, while lignin can generate inhibitory substances by combustion/pyrolysis, and different crop straws contain three components in different amounts.
Aiming at the technical problem, the invention improves and innovates the preparation method of the straw source tobacco water. The invention firstly provides a method for preparing high-quality crop straw source flue gas water by adopting a double-low pyrolysis method.
The double low pyrolysis method is: under the condition of oxygen deficiency (the oxygen content is less than or equal to 12%), heating to the low pyrolysis temperature at a low heating rate, and maintaining the low pyrolysis temperature for pyrolysis. Wherein:
the low heating rate means that the heating rate is required to be lower than 5 ℃/min during straw pyrolysis, and researches show that the difference of the heating rates causes the straw pyrolysis to move to different roads: the straw is carbonized due to low temperature rising rate, and simultaneously, the generated gas contains substances such as KARs and the like which promote the germination of seeds; the high temperature rise rate enables the straws to generate combustible gases such as tar, methane and the like. Through a large number of experiments, the temperature rise rate is controlled to be 2-4 ℃/min, and the gas generated by pyrolysis is more favorable for promoting the germination of seeds.
The low pyrolysis temperature refers to that the temperature of the pyrolysis furnace is set to 200-220 ℃ according to the pyrolysis temperature difference of cellulose, hemicellulose and lignin, and pyrolysis is continuously carried out for 1.5-2.5h after the set temperature is reached.
In one embodiment of the invention, a method for preparing straw-derived tobacco water is provided, comprising the following steps:
taking crop straws as a raw material, heating to 200-220 ℃ under an anoxic condition, and continuously pyrolyzing for 1.5-2.5 h; and (3) leaching and dissolving the flue gas generated in the pyrolysis process in water to prepare the straw source flue gas water.
According to the invention, the smoke water is prepared by a double-low pyrolysis method (low heating rate and low-temperature pyrolysis), so that the pyrolysis of cellulose and hemicellulose in the straw is increased, and the pyrolysis of lignin is reduced, thereby preparing the high-quality smoke water with good effect and stable content of effective components.
The research of the invention finds that compared with the method for preparing the tobacco water by directly burning the straw raw material, the tobacco water prepared by pyrolysis has the capability of promoting the seed germination which is obviously better than that of the tobacco water prepared by burning.
The straw source tobacco water prepared by the invention has various applications, and especially has outstanding effect on preventing and controlling weeds in fields. As described above, difficulty in weed control is related to complexity of a soil seed bank, and a large number of seeds with various varieties are accumulated in soil for a long period of time, and the dormancy degrees of the seeds are different, so that the seedlings are scattered, and the prevention is not facilitated. The straw source tobacco water prepared by the invention is diluted and then applied to soil, so that weed seeds in the soil can germinate intensively, and then weeding is carried out before weed fructification. Therefore, the number of weed live seeds in the soil seed bank is reduced, the use of herbicides is reduced, the environmental pollution is reduced, and the method has important economic and social values.
In order to make the technical solutions of the present application more clearly understood by those skilled in the art, the technical solutions of the present application will be described in detail below with reference to specific embodiments.
