To master the method of topdressing edible fungi, micro-sprinkler irrigation technology should be selected for the cultivation of edible fungi in greenhouse.

The cultivation technology of greenhouse edible fungi in China is becoming more and more mature. in the cultivation process of greenhouse edible fungi, micro-sprinkler irrigation has gradually replaced the traditional artificial irrigation, and its characteristics of saving water, increasing production, time and labor are deeply loved by farmers. The following is a brief introduction to the favorable effects of micro-sprinkler irrigation on the temperature and humidity in the greenhouse and the yield of edible fungi.

1. The effect of micro-sprinkler irrigation on the temperature and humidity of greenhouse. Temperature and humidity are the main environmental factors for the growth of edible fungi. In different seasons, the measures to adjust the temperature and humidity of the greenhouse, in addition to taking the corresponding lifting facilities, water spraying can play a certain role in regulating the temperature and humidity. If you spray water three times a day, the relative humidity can be maintained at about 85%. In practice, the daily water spraying times should be flexibly mastered according to the season and climate change, generally spraying more in sunny days, less spraying in cloudy days, and stopping spraying in rainy days. In summer, the water temperature is lower than the air temperature, and water spraying can lower the temperature, because water vapor evaporation can also take away part of the heat, so the use of micro-sprinkler irrigation in summer can increase the suspended water molecules in the air, and the cooling effect is more obvious. generally, water is sprayed 3-5 times a day, and the greenhouse temperature can be 2-4 ℃ lower than the air temperature.

2. Effect of micro-sprinkler irrigation on yield and quality of Pleurotus ostreatus. During artificial watering, most of the water is lost, and the humidity of the greenhouse mainly depends on the evaporation of ground water. When the weather is dry, young mushrooms are easy to lose water and dry up. After the use of micro-sprinkler irrigation, the water is atomized, stays in the air for a long time, and is not easy to produce dead corners, the bacteria bags and greenhouse films are stained with foggy water molecules, and the relative humidity in the greenhouse can basically maintain about 85%, which can make the fruiting body grow normally. According to statistics, the average yield of the mushroom shed with micro-sprinkler irrigation is 10%-15% higher than that of artificial watering, and the fruiting body is smooth and fresh, and the quality index is also better than that of artificially irrigated mushrooms.

3. The influence of micro-sprinkler irrigation on production management cost. The water management of edible fungi is the largest and most difficult work in daily management. Artificial watering not only takes a lot of labor, but also consumes a lot of water. After adopting Hui sprinkler irrigation, not only the labor intensity is greatly reduced and the productivity is liberated, but also the water resources are saved and the management cost is greatly reduced. According to statistics, compared with artificial watering, micro-sprinkler irrigation can save about 300 tons of water per mu per year, reduce 350 labor, and recover all the investment in one year.

Micro-sprinkler irrigation technology is adopted in the water management of edible fungi, which not only saves labor and cost, but also greatly saves water resources. it is the main measure for the transition from traditional artificial irrigation to modern automatic sprinkler irrigation in the 21st century. The water sprayed by micro-sprinkler irrigation is in the shape of fog and is very uniform. It is sprayed 2 or 3 times a day, which has an obvious effect on regulating the temperature and humidity of the grid and the microclimate in the field. When using the micro-sprinkler irrigation system, the water source should be clean and free of impurities, otherwise the micro-sprinkler will be blocked and the spray effect will be affected. after using it for a period of time, the filter should be cleaned to prevent the pressure from falling and affect the atomization effect.
