[0041] Example 1
[0042] Pretreatment of raw materials:
[0043] Sawdust is sliced and crushed and treated with an 8-mesh screen. The sifted sawdust needs to be piled for fermentation for more than 6 months. During this period, the pile will be turned over once every 15 days, and watering will be carried out once every 5 days to overflow the bottom of the pile. Without flow.
[0044] Corn cobs are dried until the moisture is below 13%, crushed and screened through an 8 mesh screen. The corn cobs need to be pre-wet for 12 hours before use. When the temperature is higher than 18℃, the surface of the pre-wet is sprinkled with lime and lime. The amount is based on the next day's production without rancidity and smell.
[0045] The corn flour and soybean meal powder are separately dried to make the moisture less than 13%, and then crushed by a 2.0 aperture grain crusher.
[0046] Pleurotus eryngii culture medium was prepared: corncob 28%; sawdust 20%; bagasse 12%; bran 20%; soybean meal 10%; corn flour 8%; calcium carbonate 1%; calcium hydroxide 1%. At temperature 15℃; CO 2 Concentration: 5000ppm; the fruiting under the condition of 80% relative air humidity, the whole cultivation cycle is 55 days, the biological conversion rate of Pleurotus eryngii can reach 85% or more, and the crude protein content in the substrate can reach 9% after testing. Above; total acid reaches above 7.5; polysaccharide content reaches above 109mg/kg (Xi'an Guolian Quality Inspection NOJC20170097), and first-grade mushrooms are obtained after harvesting.
[0047] The first-level waste is de-bagged, crushed, and screened, and used immediately to prevent mildew.
[0048] The proportion of Xiuzhen mushroom culture material is: waste 45%, cotton stalk 15%, corn cob 10%, bagasse 8%, bran 20%, calcium carbonate 1%, calcium hydroxide 1%. Among them, the cotton stalks are stacked for more than 3 months, and the other raw materials are processed in the same way as Pleurotus eryngii. The Xiuzhen mushroom culture medium is used to cultivate the Xiuzhen mushroom. After the first three tidal mushrooms are harvested, secondary waste is obtained. Xiuzhen mushroom fruiting is a temperature-controlled fruiting of the refrigeration unit, which belongs to factory production. Because its fruiting temperature is higher than that of Pleurotus eryngii, the investment capital is relatively low. The traditional Xiuzhen mushroom fruiting can generally produce 6 to 7 times of fruiting, and can fully exert the nutrients. The biological conversion rate is generally between 80 and 84%. Correspondingly, its warehouse turnover rate is reduced, and the fruiting cycle is average. In about 60 days, it is suitable for small-scale production in greenhouses. The method of the invention can exert better nutrition in the first three tides, the biological conversion rate reaches about 70%, and the fruiting period is only 22 days. Although the single package yield of the Xiuzhen mushroom culture method provided by the present invention is 10% lower than that of the traditional method, the turnover frequency is nearly three times that of the traditional method, which greatly improves the utilization rate of the warehouse, and the economic benefit is higher than that of the traditional method. The nutrition of the bacteria bag can also be recycled.
[0049] After the secondary waste is obtained, the present invention breaks the secondary waste into dryness to prepare the Agaricus bisporus culture substrate, which includes the following components by mass percentage: Step 2) 38% of the secondary waste, dried Cow dung 25%, dry wheat straw 30%, rapeseed meal 3.5%, superphosphate 1%, calcium carbonate 0.7%, lime 1.3%, urea 0.5%; after the above-mentioned proportions are prepared, the present invention carries out the heap fermentation of the above-mentioned raw materials , The temperature will rise above 60 ℃ within 24 to 48 hours, keep the temperature for 48 hours and start turning over. Be sure to turn the pile evenly and thoroughly, and turn the low-layer special materials into the middle and upper part of the pile as much as possible to fully decompose. After turning the pile for the first time, it will be turned over every week thereafter. However, when the temperature exceeds 70°C, the pile must be turned over immediately, otherwise the beneficial microorganisms and fermenting bacteria will be killed in large quantities, which is not conducive to fermentation and maturity. After obtaining the fermented Agaricus bisporus culture medium, the present invention uses the Agaricus bisporus culture medium to cultivate the Agaricus bisporus, and after 6-8 pre-harvesting the mushrooms, third-level waste is obtained;
[0050] After the tertiary waste is obtained, the present invention mixes the tertiary waste and pig manure for pile fermentation, inoculates 1L of liquid high temperature cellulosic bacteria per 100 kg of raw materials, and ferments for 45-60 days according to the temperature, and turns the pile in time as organic fertilizer. , The production of corn, soybeans and wheat, and the processing waste produced by corn, soybeans and wheat is used as the raw material for the production of Pleurotus eryngii to achieve the purpose of recycling production.
