New cultivation techniques of Auricularia auricula

The new technology of three-dimensional cultivation of Auricularia auricula in large bags can not only solve the problems of low yield and easy pollution of Auricularia auricula in bag cultivation, but also has the advantages of no limitation of climatic conditions, sites, resources and funds, saving labor and materials, high yield, excellent quality, easy cultivation, short cycle and high benefit. I. Vegetable greenhouses, vacant sites, balconies, rooftops, forest trees and other sites can be used for cultivation sites, but they should be close to water sources, well ventilated and far away from pollution sources. 2. The best ear growing period is when the local temperature is stable at 15℃~25℃. 3. Preparation of raw materials 1. Cottonseed hull 90%, bran 5%, corn flour 3%, lime powder 1%, gypsum powder 1%. 2. corn kernel flour 80%, bran 10%, corn flour 5%, soybean flour 2%, quicklime powder 2%, gypsum powder 1%. Fourth, the bagged bacteria bag can choose 22 cm ×38 cm ×0.04 cm high density polyethylene tube. When loading, try to pack tightly, do not make gaps between bags and materials, tie tightly to prevent the formation of water bags, so that cultivation failure. Sterilization generally uses steam sterilization, according to the size of the production of different specifications of the boiler. Home cultivation can be modified into steam generator by iron bucket. When restructuring, cut a hole on one side of the iron barrel, insert a steel pipe with a diameter of 2 cm into the other side of the barrel from the opening, and then weld the opening and the steel pipe tightly. Make a 4 cm opening at different locations on the same side of the opening and weld it tightly with a 4 cm short steel pipe (inserted slightly into the wall of the drum). 2 cm pipe as a water pipe, 4 cm pipe as an exhaust pipe, brick to build a stove, the bucket will sit on the stove, after adding water in the bucket can be burned in the stove, so that steam generation. Sterilization should often add water in the middle to avoid drying the barrel, affecting the amount of steam generated. VI. After the inoculation personnel enter the inoculation room, they can first carefully scrub their hands with 75% alcohol cotton balls, and then each group of 3 people, one person digs out the strain from the bottle, and two people unpack and tie the bag. Two to three pieces of red jujube strains can be inoculated into both ends of each bag. All bacteria bags should be connected at one time, and no random access is allowed in the middle, otherwise it can be operated again after re-fumigation and sterilization. 7. Germ management After inoculation, the bacteria bag is placed in a clean room or in a greenhouse and cultured in the dark. Keep the temperature at 25℃~28℃. Do not ventilate in the first 5 days. The temperature can be increased by using the method of brightening or shading in the shed. When brightening, the bag stack should be shaded with black film or straw curtain. After 5 days, proper ventilation is appropriate, and the humidity is kept below 70%. After 40 ~50 days of cultivation, the mycelium can be transferred to ear management after full bag. 8. Ear management 1. Site management. If the ear site is selected in the shed, a small earth ridge of 15 cm wide and 15 cm ~20 cm high can be made in the shed, and the earth ridge spacing is 80 cm. Outdoor earth ridges can also be made according to this method. For example, on hardened ground, a layer of bricks can be laid according to the above distance. 2. Bacteria bag opening. After preparing the field, you can cut the ear opening of the bacteria bag. First, clean the surface of the bag with 1% potassium permanganate solution or 0.2% chlorpheniramine solution, and then use a sharp blade to cut 4 ~6 "V"-shaped openings at both ends, and the upper diameter of the opening is about 2 cm. 3. Place the bacteria bag. After marking the mouth, lay the bacteria bag flat on the soil ridge, the distance between the bags is 5 cm ~8 cm, the middle is filled with soil, if it is hardened ground, it can also be filled without filling, and the upper part of the bag should be filled with 2 cm ~3 cm thick soil layer, and then arrange the second layer of bacteria bag according to the first guide swing method. For those who do not fill, put two small bamboo poles with a diameter of 2 cm to 3 cm on the first layer bag, and then put the second layer of bacteria bag. In this way, 6 to 8 layers are placed in turn. Finally, lay a film near the mound to prevent soil particles from splashing on the ears when spraying water.
