Wild and High-yielding cultivation of Pleurotus ostreatus in Winter and Spring

The Pleurotus ostreatus produced by imitating wild cultivation technology can not only taste like wild delicacy, but also achieve high ecological quality and high yield. Even in cold winter and low temperature in early spring, we can make full use of ground temperature to produce thick, fresh and tender Pleurotus ostreatus in the relatively airtight shade shed. The yield of this method is more than 60% higher than that of conventional cultivation, more than 40% higher than that of bacterial wall and other cultivation methods, and the biological conversion rate can reach more than 220%. The specific cultivation techniques of Pleurotus ostreatus in winter and spring imitating wild high yield and high quality are as follows:

The main results are as follows: 1. mycelium culture is sterilized under high pressure or atmospheric pressure, and the mycelium which is physiologically mature can be cultured according to routine inoculation. the mycelium can also be cultured with the fermentation material obtained by high temperature and strong alkaline treatment. The specific method is to add 4% quicklime to the mixture, add it in the form of lime water, mix the material well, and then pile it in a pile of 1000 kg. When the temperature of the material is above 60 ℃, keep turning the pile for 24 hours, repeat for 2 or 3 times, when the raw material is sticky and elastic, tea brown, no smell, PH 7.5 or so, water content about 65%, spread out to cool down. The raw materials can be cottonseed husk, corncob or other substitute materials, regardless of clinker, fermentation material or raw meal full of bacteria bag. The strain used is a high-quality strain with good comprehensive characters in the local area.

Second, the construction of shade sheds choose high-quality land with vegetable gardens, courtyards or sandy loam soil to build sheds. The shed uses a border with a length of 20 meters, a width of 1.3 meters and a depth of 0.22 meters, with two beds as a shed, with sidewalks left in the middle and solid around the beds. When arching, the bamboo with a diameter of more than 4 cm is used to fold and hold the arch, and then reinforced with horizontal bamboo, covered with film and covered with grass grass (which can also be a shade woven with all kinds of straw).

Third, the code of the bacterial bag, take off the plastic film of the bag which is 30 cm long (if it is a long bag) and press the tilt 75 # 35282; put the bag in the code until the bed is full, when the bag is full, you must carefully check whether the bag is infected with miscellaneous bacteria. If so, use sharp tools to eliminate the spread of the disease.

Fourth, the best soil covering material is loam, which is treated with 1% lime powder in late autumn, winter and early spring, and 3% lime powder in late spring, early autumn and summer. The treatment method is to mix the lime powder evenly into the soil in order to avoid big bumps. The treated soil can be covered with a bag of bacteria placed in the yard, and the soil at the top of the bag should be 1.5 cm thick and swept flat with a broom.

Fifth, irrigation requirements can be used to pump groundwater or use other clean water sources, flood irrigation from one end of the border until the border is fully permeated, and keep the water in the border for about 12 hours (if the mushroom bag is easy to float, it can be leveled after water infiltration). After flooding irrigation in this way, part of the overlying soil may sink, and after the water in the border is permeated, a layer of soil is sprinkled and swept flat, and then sprinkled with nutritious water (2% urea, 0.2% magnesium sulfate, zinc and Gaomeshi or other auxins, high-efficiency liquid compound fertilizer, etc.), so that the newly scattered soil is wet and does not sink, and the skin can stick when it is slightly dry.

6. the principle of high yield is to produce Pleurotus ostreatus according to the conventional method. the main factor restricting the high yield is that after the first stubble mushroom, the loss of water and nutrients is difficult to supplement, the mycelium is easy to aging, and it is difficult to produce the second or third stubble mushroom. By using this technology, the nutrient water can be irrigated once for each harvest of mushroom, which can keep the mycelium relatively nutritious and sufficient water, and can effectively prolong the mycelium life and mushroom production period. About a week after soil mulching and irrigation, the new mycelium connects the whole bacterial bag into one. In the process of mushroom emergence and growth, the soil constantly supplies nutrients and water to the mycelium, so the mushroom body is still fat, fresh and tender when it comes out of the second or third stubble. In addition, due to the suitable humidity and good shading in the greenhouse, from the formation of small mushroom buds to mature harvest, the environment of long mushrooms is like that in wet shady land, which overcomes the disadvantages that it is difficult to control the humidity in conventional cultivation space and it is difficult for bacterial bags to supply nutrients and water. In addition, micro-fertilizer, hormone and auxin can infiltrate into the soil with irrigation, which is convenient for mycelium absorption and utilization, so it can obtain stable and high yield, high quality and high efficiency.
