New method for mushroom-free manure cultivation

With the popularization of mushroom cultivation techniques, methods for mushroom cultivation have also been continuously improved. General cultivation of mushrooms are used as raw materials for livestock manure, but the disadvantage is that the odor is large. The following introduces the new technology of mushroom-free manure cultivation introduced in recent years for reference. First, mushroom no manure cultivation formula (in terms of 100 square meters). Dry straw such as straw 1500 kg, urea 15 kg, ammonium bicarbonate 20 kg, lime powder 50 kg, peanut bran 75 kg (or 100 kg of vegetable bran), superphosphate (50 kg), gypsum powder (50 kg). The suitable ratio of carbon to pure nitrogen before fermentation of the culture material is between 30-31:1. About 17:1 after fermentation (Note: Slightly different strain types). Therefore, the preparation of culture materials must pay attention to the ratio of carbon and pure nitrogen content. In addition, to obtain the best yield, it is best to use secondary fermentation technology or warming agent fermentation technology. Second, the cultivation of material fermentation method. Composting method: In recent years, new technologies have been grouped in advance. Forage, nitrogen fertilizer (ie, urea, ammonium bicarbonate) and lime powder are a group, and other superphosphate, gypsum flour, and bran cake fertilizers are used as a group. When the forage is turned for the first time (ie, about 6 days) Mixed composting. Specific methods: fodder 1-2 days in advance pre-wet, and then build a heap, according to a matching layer of wet grass a layer of lime powder, a layer of wet grass a layer of nitrogen fertilizer (Note: lime and fertilizer can not be the same layer), such a layer Layers sandwiched, until 1.5 meters high. Each layer of grass thickness 15-20 cm, material piles 2 meters wide, 1.5 meters high, the length is determined by the number of materials used per 100 square meters (that is, 1500-2000 kg of hay) 8-10 meters long heap. The top of the pile is shaped like a turtle, surrounded by vertical and squarely-growing square-shaped material piles; when the pile is built to a certain height (about 50 cm), each layer should be properly watered, and a small amount of water around the material piles on the next day is appropriate. Turning: After every 5 days, 4 days, and 3 days, they are piled up once. Generally, they are turned 3 to 4 times (mixed heaps), and the composting period is about 18-23 days. Every time the pile is turned, the material should be shaken loosely, and the upper, lower, inner and outer materials should be positioned opposite to each other. In the first two rounds, the horizontal type and stripped type were used for layer-turning. In the latter stage, straight-type and mixed-type turnings were used. During stacking, if the weather is dry, the stockpiles are relatively dry. In the early stage, the dumping can be preceded by pouring some water around the stockpiles before turning over. The water in the stockpile should be well adjusted in the early stage. During the later stage of the composting fermentation (after the second or third turnover), no matter can be added to anything. When the last turn is made, the masonry mat is used to remove the wood 15-20 cm from the ground. Then pile up the material on top and insert a few rough bamboo or wood sticks vertically, one at a time every 0.8 meters, and remove them on the second day after the completion of the stack to form a ventilation hole to facilitate the increase of air permeability of the material pile and eliminate exhaust gas and odor. Flavors can greatly improve the quality of culture materials. After the inoculation, mushroom room preparation, complex soil, mushroom management and other work is basically the same with the conventional cultivation methods, mainly mushroom house, materials to be thoroughly disinfected and ventilation, humidity control and insulation work.
