Understand how to cultivate edible fungi and the application of fog irrigation in the cultivation of edible fungi in greenhouse

As the main area of cultivating edible fungi, greenhouse has very strict requirements on the irrigation mode of edible fungi. Fog irrigation is a new water-saving irrigation technology rising in recent years. Water-saving irrigation techniques such as sprinkler irrigation and drip irrigation are difficult to meet the normal growth needs of edible fungi. Therefore, fog irrigation has become the main irrigation method in the cultivation process of edible fungi in greenhouse.

Fog irrigation is a new irrigation technology rising in recent years. Fog irrigation combines the advantages of sprinkler irrigation and drip irrigation and abandons their disadvantages. Fog irrigation is the irrigation water through the pressure, through the pressure pipe network to the irrigation area, and then through the special atomization sprinkler to spray the irrigation water evenly to the field, because its raindrop diameter is usually smaller than 0.5mm, like cloud, so it is named fog irrigation. The effect of fog irrigation is good, which can not only meet the needs of normal crop growth, but also increase the air humidity among crop plants, adjust the temperature between crops, and improve the field microclimate. Compared with sprinkler irrigation, the equipment of fog irrigation system is less, the early capital investment is lower, and the effect of increasing production is obvious, which can usually increase production by about 50%, and the economic benefit is remarkable. And fog irrigation will not appear the phenomena of field runoff, soil surface consolidation, soil erosion and reducing fertilizer efficiency that often occur in the use of sprinkler irrigation. Compared with drip irrigation, fog irrigation has stronger anti-blocking and lower requirements for water quality, and the water-saving effect is better than sprinkler irrigation, which can usually save more than 60% of water. And fog irrigation will not appear in the use of drip irrigation in the process of excessive plant root water is easy to induce plant root diseases, inhibit plant growth and soil salt accumulation.

But correspondingly, fog irrigation also has some shortcomings. Fog irrigation is not conducive to reduce the air humidity in the greenhouse, too high air humidity is easy to cause large-scale diseases of edible fungi, so attention should be paid to the ventilation of the greenhouse in the process of use. At the same time, sprinkler irrigation will hinder the photosynthesis of crops in the greenhouse, reduce the accumulation of organic matter in edible fungi, and indirectly affect the yield and quality of edible fungi. In the process of use, the above phenomena should be avoided to ensure the yield and quality of edible fungi in the greenhouse.
