Abstract
The present invention belongs to the field of irradiation treating technology, and is especially method of irradiation degrading crop stalk to prepare edible fungus culturing material. The present invention opens one new way of utilizing crop stalk. The method includes cutting stalk into 3-5 cm long, mixing with 1/20 concentration lime water to alkalize, piling to ferment for 15-25 days, compounding with supplementary material determined based on the variety of edible fungus to be cultured, hermetically packing and irradiating in the irradiation dose of 12-15 kGy and irradiation dose uniformity within 1.5, and using the irradiated material for culturing edible fungus. Or, the crop stalk is fermented preferably in a fermenting tank before compounding material, irradiation degrading and sterilizing to produce the edible fungus culturing material.
Description
Technical field
Atomic energy technology, the RADIATION PROCESSING field, irradiation natural polymer vegetable matter utilizes new technology again.China book classification TL99, subject classification number 490.55.
Technical background
The natural macromolecular material crop stalk, the synthetic annual production of China's natural biology is more than 500,000,000 tons, and how to handle is major issue during current China sustainable agriculture is produced, and traditional treatment method is burning and returns the field, the former not only causes environmental pollution, even burning dense smoke influences shipping industry; The latter needs a cover special-purpose machinery to cooperate the cost height.
Crop stalk is made up of the plant skeleton that cellulose, hemicellulose and lignin constitute, in recent years, it mainly is to be used for papermaking that a small amount of straw carries out commercial Application, different with the straw papermaking wastewater with the timber papermaking wastewater, its waste liquid Main Ingredients and Appearance is a lignin, be difficult to reclaim, also difficult the decomposition, cause environmental pollution with alkali.China mainly is paper industry because of waste water causes environmental pollution according to statistics, accounts for 30%.Also have straw alkalization (or acidifying), stack degraded, reprocessing is as animal feed.Because of being subjected to natural environment to change (as wind, rain, temperature etc.), its technology is difficult to grasp, while cost height, and the output value is low, the difficult popularization.As seen the new way of seeking the straw economic utilization has become the task of top priority.
Summary of the invention
The present invention is directed to the problems referred to above, propose the new method of economic utilization straw, it is characterized in that: straw is cut to 3-5cm, with the alkalization of 1: 20 limewash, stack high 2.0 meters, 1.5 meters of diameters, seal with soil, stacked 15-25 days according to temperature, make its fermentation, require in addition different auxiliary material to make cultivate material according to different culturing edible fungus differences, again by the cultivation requirement, pack, as bottled, packed; By the big packaged by plastic film of outdoor protection ground cultivation requirement, after packing is finished, irradiation 12-15kGy, the irradiation dose unevenness is less than 1.5, and the cellulose small amount of degradation that alkalizes is a carbohydrate, and sterilization can be made composts or fertilisers of cultivating mushroom simultaneously.
Be that standardization produces, also available fermentation tank, will shred straw with the fermentation tank industrial fermentation after, prepare burden irradiation-induced degradation again.Add behind the auxiliary material if be mixed with mushroom cultivation material, then 1 kilogram of straw is through chopping, lime alkalization, add auxiliary material again, mushroom cultivation is carried out in the irradiation-induced degradation sterilization, can produce 1 kilogram of flat mushroom approximately, its cost is 0.2 yuan in a lime, 0.4 yuan of auxiliary material, 0.2 yuan of labour cost, irradiation takes by 800 yuan of calculating per ton, then is 0.8 yuan of per kilogram, 1.6 yuan of totle drilling costs, and the flat mushroom market price is 3 yuan of per kilograms, 1.6 yuan of wholesale price per kilograms.This shows that it is profitless cultivating general edible mushroom with this method, have only cultivation high-grade edible bacterium or medical, edible bacterium, its bright mushroom purchase per kilogram just has rich profit more than 4 yuan.
This method not only economic implications is huge, and its environment protection significance can not be ignored, and a large amount of straws become composts or fertilisers of cultivating mushroom, and the waste material after the edible mushroom cultivation can directly fertilize the soil, and also can dry, be pressed into pellet.
Description of drawings
Figure of description is the irradiation degrading crop stalk to prepare edible fungus culturing material process chart.Rice or wheat or millet straw drying are chopped into 3-5cm, fully mix thoroughly with 1: 20 limewash, the limewash consumption is stacked outdoor choosing arid soil with moistening straw, and heap is unsuitable excessive, 1.5 meters of diameters, high 2.0 meters is good, loam cake earth, not bleeding with rainwater is principle, pilling up time, the decision outside air temperature, summer, temperature was high 15 days, winter, temperature was low 20-25 days, temperature 15-18 days spring and autumn.About 30 ℃ of straw temperature and fragrant is arranged is good behind the reactor startup.With the back straw that alkalizes is base-material, is equipped with various auxiliary materials according to cultivating high-grade edible bacterium (or medical, edible bacterium), pack, if bottled cultivation, in the bottle of then packing into, if the outdoor cell cultivation, then by the pack of every sub-district consumption.Use behind the package encapsulation
60Co gamma-rays or 9-10MeV electron beam x ray irradiation x, irradiation dose is generally 12kGy, if original bacteria containing amount is higher or make to cultivate edible mushroom seed usefulness, then irradiation dose can be brought up to 15kGy, the irradiation dose unevenness is less than 1.5.
Specific embodiments
Embodiment 1: wheat class stalk, drying, chopping 3-5cm, mix thoroughly with 1: 20 limewash, be degree from holding the stalk expressed water, stack on the outdoor highland of selecting again but add the lime water yield, pile high 2 meters, 1.5 meters of diameters tightly cover Tanaka's earth on every side, and the water that do not bleed to rain is principle, looking temperature just stacked 15-25 days, during reactor startup, about 30 ℃ of stalk temperature and fragrant is arranged is good are equipped with the cultivation champignon adjuvant, pack irradiation 15kGy, the irradiation dose unevenness promptly cultivating plastic greenhouse inoculation mushroom, is cultivated less than 1.5, after the mushroom results, the dry powder of beating of bacterium chaff, in addition auxiliary material is made all feeds.
Embodiment 2: stalks cutting 3-5cm, use industrial fermentation tank, fermentation back stalk is equipped with the mushroom culture auxiliary material, pack irradiation 12kGy, the irradiation dose unevenness is less than 1.5, can be behind the irradiation at the greenhouse culture mushroom, and after the results, bacterium chaff drying, beat powder, in addition auxiliary material is made feed.
Claims (2)
1. the method for agricultural crop straw irradiation-induced degradation composts or fertilisers of cultivating mushroom, this method feature is that crop stalk is shredded 3-5cm, and is moistening with 1: 20 limewash, after mixing thoroughly, pile highly 2 meters, 1.5 meters of diameters with soil sealing, are stacked after 15-25 days, be equipped with auxiliary material according to the culturing edible fungus kind, after the packing, use
