Summer mushroom high-yielding essentials
In recent years, the mushroom production in Beiyang Village, Wangdu County, Baoding has developed rapidly. However, high temperatures and high humidity and the rapid spread of pests and diseases have caused great difficulties for the production of oyster mushrooms. The author believes that the following points must be taken into account in summer production:
First, the selection of bacteria. Select varieties with high temperature resistance, good mushroom shape, high yield, and strong disease resistance. Such as: Hainan No. 2, Spring Planting No. 1, Ho's 200 and so on.
Second, ingredients processing. Appropriately reduce the amount of nitrogen fertilizer. Appropriately increase the amount of plaster.
Third, build a heap fermentation. Minimize the factors that cause poor ventilation. The sign of good fermentation is that the culture material is brownish red, has aroma, and has a large number of white actinomycetes mycelium.
IV. Inoculation
1. In order to increase the success rate, clinker production should be adopted in high temperature season and two inoculations should be conducted. The 2040 cm high-density polyethylene bag was used and was sterilized at atmospheric pressure for 8-12 hours. The inoculation temperature is lower than 30°C; strains should be spread as evenly as possible to cover the material surface; the culture room should be shaded, ventilated, and vents should be screwed on the yarn cover.
2. Put the well-shaped discharge bags or bacteria on the ground. Two bamboo rods are placed in parallel between each layer of bacteria bags. According to the temperature condition, the distance between the layers and the bags in each layer and the rows should be determined. Daily check the material temperature, material temperature exceeds 30 °C immediately bag cooling.
V. Mushroom management
1, can code 2-3 layers (middle partition bamboo or wood), rod spacing 2-3 cm, a layer of plastic woven bag on the ground, put square tiles on the bag to ensure the mushroom body clean. In the event of a sudden high temperature, it is necessary to splash water on the ground or wall in a timely manner or cool down.
2. Use a small blade to split the two ends of the mushroom bag along the edges, try not to cover the surface, and wait until the primordium appears at both ends and then separate the flaps.
3, shading at the same time combined with night ventilation, spray cooling and other measures to regulate the temperature within the shed is about 25 °C, in order to ensure the normal growth of Pleurotus ostreatus.
Six, pest and disease prevention. The pests and diseases of Pleurotus ostreatus in summer should be based on prevention.
1, before cultivation, the use of the room, greenhouses for a comprehensive disinfection and pest control, such as spraying pesticides in the house, sprinkle lime powder, the room with formaldehyde, potassium permanganate sterilization.
2. During the fruiting period, it is forbidden to use unclean river water or pond water.
3, at high temperatures, the cultivation of Pleurotus ostreatus prone to green mold, mushroom yellow, mushroom fly, mushroom mosquitoes, aphids, and other pests and diseases found in the fruiting stage insects, insects can be used Rickett, mushroom insect net, mushroom guards, cypermethrin Wait for spray or injection into the cultivation bag. Mushroom yellow disease, alternating with agricultural streptomycin, mushroom king, rot fungi and other drugs.
