Gaoyang Township, Linzi District, Zibo City, Shandong Province made mushroom in the summer maize row, which increased land utilization and multiple cropping index. Pleurotus ostreatus from the species to close only 50 days, short time, quick effect. Intercropping maize has high economic benefits, ecological benefits and social benefits. 1. Maize 1 plot. To choose near water, loose land and fertile land. 2 varieties. To choose a plant type that is compact and suitable for planting shading, such as the Shandan 2 and so on. 3 planting specifications. In order to adapt Pleurotus ostreatus with summer corn during the mushrooming period, and at the same time to enable timely wheat in the autumn, corn should be interplanted in wheat in late May, using large and small rows of planting methods with a large row spacing of 60 cm and a small row spacing of 40 cm. 28 cm, with an average spacing of 53 cm, and a density of about 4,500 plants per mu. 4 field management. When interplanting Mu, soil and fertilizer, 75 kg, 75 kg of phosphate fertilizer, timely treatment of corn after the emergence of corn, wheat immediately after the harvest, and deep plowing, small bell-mouth acres of 40 kg of urea topdressing. After the Other management measures with Daejeon. 2, mushroom 1 species. To choose high-temperature or wide-temperature varieties, such as 831, HP-1, Jiuhua 191, CCEF89 and so on. 2 preparation of culture materials. Select fresh, dry cottonseed hulls, add 5% slaked lime, 2.5% superphosphate, 0.3% urea, 0.25% carbendazim (40% content), 130% to 150% water, and mix thoroughly. 3 sowing. Pleurotus ostreatus sowing period is suitable from corn jointing to small bellmouth stage. In mid-July and late July. 1 to 2 days before sowing, dig 40 cm wide and 20 cm deep in a row between the big corn rows. Leave a walking path for one line and use 20 kg of cottonseed hull per 1 square meter. Use layered inoculation and seeding on the surface for seeding, using 10% to 15% of dry cotton seed hull. Before sowing, firstly pour water into the pot. After the water seeps, disperse small amount of slaked lime evenly in the mushroom pot. Dispense the prepared culture material and strain block (about 1 cm in diameter) into the pot. Layers 1, 3, and 5 are species, which occupy 20%, 35%, and 45% of the species, respectively. Layers 2 and 4 are culture materials. When planting, the culture materials should be compacted, and the bacteria seed blocks should be evenly spread. Finally, a layer of plastic film should be placed on the surface and the plastic film should be covered with 10 cm thick wet soil to protect the water. 4 Field management and harvesting. About 10 days after the Pleurotus ostreatus was sown, the growth of mycelium was observed. After about 20 days, after the mycelium grows (the culture material turns white), the topsoil and mulch are cut off. After 2 to 3 days, when the buds grow to 1.5 cm in diameter, they can spray water once in the morning and in the evening. When drought occurs, the number of water sprays can be appropriately increased. From the appearance of small buds to the first harvest, it takes about 4 to 5 days. The first crop accounts for more than 40% of the total production. After the first crop is harvested, the ravioli is cleaned in time, the dead mushroom is eradicated, field management is strengthened, and the contamination of the culture material is observed constantly. If the contamination of the bacteria is found, the contaminated block is promptly removed with a sterile knife and used with 10% of the total. Lime water disinfection. After another 3 to 4 days, mushroom buds will appear, and the above management measures will be repeated. When the corn is harvested, the oysters can be harvested for 3 to 4 days. During this period, the agricultural film can be covered in case of rain. 3. Benefits Intercropping Pleurotus ostreatus between corn lines averages more than 2,000 kilograms per mu. Because of the carbon dioxide released from the culture of Pleurotus ostreatus in the transformation process, the photosynthetic activity of maize is increased, the maize growth is not premature, and the number of grain per spike and grain weight is increased. Therefore, the intercropping area has 612 kilograms of corn per mu, and the non-intercropping area is 200 mu. Produce 578 kilograms, increase production 34 kilograms (5.5%). After the oyster mushroom was harvested, the waste bacillus together with a large amount of mycelium turned into the soil before the fall season to loosen the soil, thereby changing the physical and chemical properties of the soil and increasing the content of various nutrients in the soil. In the second year, soil testing results showed that soil bulk density decreased 2.5 g/cm3, porosity increased by 9.5%, water content increased by 0.8%, organic matter increased by 0.679%, total nitrogen increased by 0.029%, total phosphorus increased by 0.038%, and immediate nitrogen increased by 28.7 ppm. The available potassium increased by 162 ppm, improved soil physical and chemical properties, and increased soil nutrient content.
