The invention discloses a planting method of pleurotus geesteranus. The method comprises the steps that materials are taken, and a culture medium is prepared, wherein the culture medium comprises, byweight, 15-25 parts of bacterium residues, 25-35 parts of cob cores, 10-20 parts of wheat bran, 10-20 parts of mixed saw dust, 10-15 parts of sweet potato residues, 8-12 parts of coconut shells, 4-6 parts of bamboo powder, 3-5 parts of activated carbon, 5-7 parts of bran skin, 1-3 parts of shell fossils, 2-4 parts of gypsum powder, 2-4 parts of mint, 2-4 parts of diethylaminoethyl hexanoate, 2-3 parts of fructo-oligosaccharide, 1-2 parts of chitosan, 0.05-0.1 part of guar gum, 0.05-0.09 part of sodium glutamate, 0.1-0.3 part of carbendazim and 0.2-0.4 part of urea. According to the planting method of pleurotus geesteranus, the problem of insufficient cultivation raw materials is solved, the production cost is lowered, resources are reasonably used, the yield is high and stable, the qualityis good, the growth vigor of hyphae is strong, the fruiting number is large, and mushroom shapes are in order; by controlling a ventilation structure, in summer or winter, the temperature and oxygencontent of a planting greenhouse can be controlled; the situation can be avoided that mushroom buds are frozen to be injured in winter, by adding an air cooler, cold stimulation to pleurotus geesteranus in summer can be achieved, and planted pleurotus geesteranus is fresh and tender in taste, delicious and tasty.
