Interplanting Pleurotus ostreatus in Pear Orchard

After pear harvest, the pear orchard has a long leisure time, and planting Pleurotus ostreatus in the empty row of pear trees can obtain better benefits.

1. Choose the bed site: it is best to choose a pear orchard close to the village, which requires better soil quality, irrigation and drainage, and smooth transportation.

2. Finishing the border bed: the mushroom bed is 8-10 meters long and 1.2 meters wide, and the bed soil is 15-20 cm deep. It should be finely arranged so that the soil is clean, empty and solid, pinched by hands and scattered when it falls to the ground. The bed surface is surrounded by 4-5 cm high ridges to preserve soil moisture. After the mushroom bed is finished, a drainage ditch is opened around the mushroom bed to filter the water.

3. Raw material formula: 100 kg of raw materials for 10 square meters of border bed, including 93 kg of cottonseed shell, 2 kg of gypsum powder, 3 kg of quicklime, 2 kg of superphosphate, 100 grams of carbendazim and 20 ml of Huimanfeng active liquid fertilizer, 130-140 kg of water were fully mixed with the raw materials, and then covered with the film for 5-7 days. In order to make the ingredients uniform, turn the heap and mix twice and sow seeds when the temperature of the material is reduced to 20 ℃.

4. Uniform sowing bacteria: normal temperature type or low temperature tolerant strain should be selected according to sowing date. Strain 10-12 kg for every 100 kg of raw materials. The bed was watered thoroughly before sowing. When sowing is divided into three layers of interval sowing or hole sowing, the amount of sowing in the lower layer is slightly less and that in the upper layer is larger, so as to facilitate the mycelium to cover the material surface quickly and restrain the pollution of miscellaneous bacteria. After sowing, pat the surface of the bed and cover the film, and then cover the straw.

5. Management and harvest: uncover both ends of the bed membrane 10 days after sowing, check for contamination by miscellaneous bacteria, and be properly ventilated. After 20-25 days, the film should be ventilated when the temperature in the film exceeds 28 ℃. After the mycelium was covered, it was covered in a small arch shed, and attention was paid to preserving soil moisture and promoting the formation of mushroom buds. The mushroom buds can be harvested after growing for 5-7 days. Clean the mushroom bed immediately after harvest, stop water for 2-3 days, and then cover with plastic film to promote the growth of Pleurotus ostreatus. After the harvest of Erchao mushroom, 500 times Huimanfeng active liquid fertilizer and 0.5% urea mixture were sprayed to supplement nutrition.
