Benefit technique of interplanting Pleurotus ostreatus in Pear Orchard

After the pear trees are harvested, the pear orchards have a long leisure time. Planting Pleurotus ostreatus in one season by using the empty rows among the pear trees can obtain better economic, ecological and social benefits. A nursery bed of about 10 square meters can produce more than 100 kilograms of Pleurotus ostreatus with an income of more than 200 yuan, with less input and quick effect; it can also increase fertilizer sources, improve soil fertility, improve soil fertility, increase the content of phosphorus and potassium, and kill winter weeds; it is beneficial to the secondary rooting of pear trees in autumn.

In order to interplant Pleurotus ostreatus in pear orchard, the following points should be mastered in planting techniques.

I. choose the location of the bed

First, the mushroom bed should be chosen in the pear orchard near the village.

Second, the bed should sit north and face south.

Third, the soil quality is better, drainage and irrigation are both convenient.

Fourth, it is close to the suburbs of cities and towns, and the transportation is smooth.

Second, the mushroom bed of the finishing bed is 10 meters long and 1.2 meters wide. The bed soil is ploughed 15cm and 20cm deep, and it should be carefully arranged so that the soil is clean, empty and solid, pinched into a ball by hand, and scattered when it falls to the ground. The surface of the bed should be surrounded by a ridge with a height of 4ml and 5cm, in order to preserve soil moisture. After the mushroom bed is finished, a drainage ditch is opened around it to filter the water.

Third, the border bed with a general formula of 10 square meters should use 100 kg of raw materials for the production of Pleurotus ostreatus, including 93 kg of cottonseed shell, 2 kg of gypsum powder, 3 kg of quicklime and 2 kg of superphosphate. And mix with 100g carbendazim, 20ml Huimanfeng active liquid fertilizer, 130MUR 140kg water, fully mix with raw materials, then cover the pile with 5Mel film for 7 days, in order to make the ingredients uniform, turn the heap and mix twice, wait for the material to cool to about 20 ℃, then sow.

4. The varieties of normal temperature type and low temperature tolerance type should be selected according to the sowing date. The bacteria should be white and thick, robust, without yellow water, covered with hyphae inside and outside, and pay attention to no miscellaneous bacteria and no mushroom buds. The normal temperature strain was selected for sowing in September. Low temperature tolerant strains were selected for sowing in October. For every 100 kg of raw materials, strain 10m / 12kg should be used. The bed should be watered before sowing. Sowing should be 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, which should facilitate the mycelium to cover the material surface quickly and restrain the pollution of miscellaneous bacteria. After sowing, clap the bed tightly, then cover the film, and then cover the straw.

Fifth, management and harvest and sowing 10 days after opening both ends of the bed membrane, check whether there is miscellaneous bacterial infection, can also be properly breathable. After 25 days, the temperature in the film exceeds 28 ℃, and the film should be ventilated. After the hyphae are covered, the bamboo bow should be used to arch the film, and pay attention to preserving soil moisture and promoting the formation of mushroom buds. The mushroom buds can be harvested in 7 days when the mushroom buds grow. The mushroom bed was cleaned immediately after the head mushroom was harvested, the water was stopped for 2murine for 3 days, and the plastic film was covered to promote the growth of the second stubble mushroom. After the second stubble mushroom is harvested, 500 times Huimanfeng active liquid fertilizer and 0.5% urea mixture should be sprayed to supplement nutrition and promote early and more mushroom production.
