Key points of production Technology of Edible Fungi in Autumn

I. strain selection

The cultivation of edible fungi should be based on the local environment and climatic conditions, and the excellent varieties with large size, good color, storage and transportation resistance should be selected as strains. Buy seeds from seed suppliers with good reputation, high technology and no bad record.

II. Construction of mushroom shed

The construction of mushroom sheds should be based on their respective production plans. If annual cultivation is planned, the standard of mushroom shed can be raised and winter-warm greenhouse can be adopted; anti-seasonal production should be given priority to, walls should be thickened and "greenhouse water temperature air conditioning" should be installed; only a batch of cultivation should be carried out in autumn and winter, and a single slope and plane greenhouse can be built. No matter what kind of mushroom shed, ventilation holes must be built on the basis of heat preservation and moisturizing.

3. Disinfection of mushroom shed

The new mushroom shed can be sprayed with drugs such as phoxim, phoxim, etc. in the new mushroom shed, the general dosage is 1 bag of phoxim without trace, spray 30 square meters, the ground, walls and columns should be fully sprayed, and then seal the mushroom shed and roll up the grass to bask in the shed. After sealing for 2 days, you can put bacteria into the bag or produce mushrooms. The old mushroom shed, which has been used for many years, should be thoroughly disinfected because of its large number of germs. One bag of phoxim was sprayed with 40 g phoxim without trace, then sealed the mushroom shed and rolled up the grass to bask in the shed; after 2 days of sealing, the medicine was used again and continued to seal the shed for 2-7 days before entering the bag to infect the bacteria. In addition, the site outside the shed should also be strictly cleaned, thoroughly clean up contaminated bacterial bags and bacterial bran waste, and do not litter contaminated bacterial bags, diseased mushroom bodies and cultivation waste.

IV. Material preparation

1. Raw materials. According to the variety, season and cultivation quantity of the production plan, purchase and store raw materials as soon as possible, and use local materials as far as possible. If you cultivate Pleurotus ostreatus, you should collect or buy wheat straw or rice straw, cow dung and chicken dung as soon as possible; to cultivate Pleurotus ostreatus, you need to reserve enough cottonseed shell, corncob or other crop straw; to produce Lentinus edodes, prepare hard broad-leaf sawdust in advance, or use branches or stumps to process sawdust yourself.

two。 Soil covering material. The soil covering materials of edible fungi often include peat soil, rice chaff soil, humus soil and common soil. ① peat soil is the best soil covering material for edible fungi, but the price is more expensive. ② rice husk soil. Prepare 4000kg river soil and 500kg rice husk for every 100m2 of cultivated area, dry and crush the river soil, soak the rice husk in 4% lime water for 20 hours, fully mix the two, and add water to adjust the water content to 20%, then build a pile for fermentation, and finally cover the film. Turn the pile once every 2-4 days, turn it 3-4 times, spread out the smell and then use it. ⑧ humus soil. The formula of humus soil (kg): cow dung powder 600-1000, bean cake 100, calcium magnesium phosphate 80, urea 40, lime powder 60, gypsum powder 30. Select the open space with an area of about 25 square meters near the water source, and the 10cm of the soil around it is high. After the material is crushed and mixed well, it is evenly scattered in the open space, turned deep 20cm, slightly leveled, and the irrigation is level with the cofferdam. Ten days later, the water was turned over again to maintain the height of the water surface. If the temperature is high, there will be smelly blisters on the water surface in 7-10 days. After turning over 3-4 times when the temperature is above 30 ℃, release the water. When there are a large number of wide and deep cracks on it, take out the soil layer and break it while basking. After spraying with fungicides, the film can be used for 7 days. ④ common soil. In every 100m2 mushroom shed, take the 5000kg of the soil below 20cm, dry in the sun, crush and sift. Then mix and spray with 800 times phoxim until the liquid adheres to the soil particles, build a stack and cover the film, and it can be used after a week. When in use, spread out the mound, slightly volatilize the waste gas from the soil, and then enter the shed to cover the soil.
