Pampa grass cultivation management skills : (1) Temperature : Temperature has an extremely important relationship with the growth and development of Pleurotus. The average temperature in Wuhan from April to July is 16.5-21.7 °C, which is most suitable for seedling culture. When the average temperature in August exceeds 29 °C, the growth and development of the plant will be affected. When the temperature is 38 °C for a long time. The plants stop growing or grow very slowly; when the temperature is above 42 °C, when the surface temperature is at 53 °C, the water temperature will rise, and the leaves will appear, and the heavy ones will cause the plants to die. Therefore, the water source must be kept flowing during this period. The optimum temperature for the genus Pleurotus: the monthly average temperature range is 16.5-24- 13-13 °C. When the daily average temperature (late November or early December) is about 10 °C, the plants stop growing. (2) Illumination : Light has little effect on the growth and development of P. sylvestris. It can grow normally under the light conditions in Wuhan. (3) Soil : The pH of the soil of the plant is not very strict, and it can grow normally under the condition of pH=5.5-7.5. However, fertility has a close relationship with it. The soil is fertile, the flowers are rich, the colors are bright, the flowering period is long, the whole plant grows vigorously, and the viewing period is long. On the contrary, the ornamental value is lost. (4) Selection of cylinder and pool : We choose a planting condition with a cylinder height of 65 cm, a cylinder inner diameter of 65-80 cm, a diameter of 1 x 1 m or 2 x 2 m, and a depth of 60 cm. (5) Pest control: prevention and control of water cotton (moss) can be sprayed in water with copper sulfate. The spraying concentration in seedling stage is 3-5mg/L, and the seedling stage is 30-50mg/L. Aphids can be used for 1000-1200 times of trichlorfon, dichlorvos or 2000 times with 50% dimethoate emulsion. Spiders such as Spodoptera litura can be sprayed on the surface of the leaves with 1000-1500 times of enemy killing to have an insecticidal effect. The snails can be used for tea insecticides, quicklime, and turmeric powder to achieve insecticidal effects. There is also a field management law that continuously removes water and weeds.
