When to plant Pleurotus ostreatus? Where is it suitable for planting? How to prepare culture material with coffee shell?

Pleurotus ostreatus, also known as Pleurotus ostreatus, is rich in nutrients such as protein, vitamins, minerals and polysaccharides, and is one of the top ten mushrooms in the international mushroom market. when will Pleurotus ostreatus be planted? Where is it suitable for planting? How to prepare culture material with coffee shell?

When will the mushroom be planted?

In order to cultivate Pleurotus ostreatus in natural environment, the period of mushroom emergence should be at 15-27 ℃. Pu'er City usually sows seeds from September to December and begins to produce mushrooms from December to January of the following year. Under normal circumstances, mushroom picking ends at the end of April.

Second, where is the suitable place for growing mushrooms?

Use winter fallow fields, vegetable gardens and orchards for cultivation. The selection of cultivation sites should pay attention to the following points: first, close to water source and pollution-free, convenient for drainage; second, loose and fertile soil, weakly acidic soil, rich in humus; third, shelter from wind and sunshade, refractive index is required to achieve "three points of yang and seven points of shade".

Third, how to prepare the culture material with coffee shell?

Pleurotus ostreatus can be cultivated with raw material or pre-fermented material or clinker. Raw material cultivation, in the process of strain germination, the culture material will heat up, if the temperature is not controlled properly, the bacteria will be burned; the cost of clinker cultivation is high, the process is more cumbersome; pre-fermentation material cultivation operation is simple, safe and practical. The author mainly introduces the cultivation techniques of pre-fermented materials. The culture material should be fresh, dry, mildew-free and decay-free.

Preparation of culture material: the ratio of coffee shell to shavings is 1 ∶ 1, and the total amount of dry material per mu is 50008000kg. After the two substrates are evenly mixed, 10% of the total (dry) fresh wheat bran is mixed evenly before laying.

The treatment of culture material: (1) pre-wetting. The coffee shell and shavings were mixed well according to the ratio of 1 ∶ 1, and then soaked in water. The purpose of immersion: one is to make the culture material absorb enough water, the second is to reduce the pH value of the matrix, and the third is to soften it to facilitate operation. The immersion method is usually soaked in a pool (first digging potholes and lined with plastic sheeting) for 6-12 hours. The immersion standard of the culture material should be 70%-75% water content after natural leaching. The judgment method is that the material is pinched and then dripping linearly. (2) pre-fermentation. The culture material will be stacked into 1.5 meters wide, 1 meter high, unlimited length of material heap, pre-fermentation. When the material temperature rises above 60 ℃, keep it for 12 hours and 36 hours, the stack can be turned over. Turn the pile again every other day, and after 1-2 days, the pile can be broken up, adjust the pH value to 6-7, and put it into bed to spread the seeds.
