A brief discussion on the key points of management techniques of wood edible fungi in summer

Most edible mushroom growers know that summer is the main harvest time for Auricularia auricula. At the same time, after Lentinus edodes is produced in spring, the mycelial nutrition consumption is very high, and the free period of mushroom production in summer should be prepared in time for the emergence of mushrooms in autumn. The following summarizes the technical measures for the management of Auricularia auricula and Lentinus edodes in summer for your reference.

Auricularia auricula

The water management method of "dry, dry and wet, dry and wet alternately" should be adopted during the ear-out period. if there is a continuous sunny day and there are young ears on the earwood, water can be sprayed around noon; if the temperature is too high from July to August, water should be sprayed at night to supplement the water content of the earwood. When the temperature is suitable for the growth and development of Auricularia auricula, we should pay close attention to spraying water out of the ear, spray heavy water in the early stage, let the auricular wood absorb water, promote the occurrence of ear buds, spray gently and carefully after coming out of the ear, stop spraying once every 2 times every 3 days, with an interval of 2 days; after each harvest of Auricularia auricula, water should be stopped for 6 times for 7 days, according to the mycelium growth of auricula and whether the temperature is suitable, and then carry out the next crop of ear-stimulating and ear management. During the period of ear spraying, the earwood should be turned over as much as possible, so that the earwood can absorb water and receive light evenly. In case of high temperature and drought, it is especially necessary to prevent the earwood from peeling. Water spray must be carried out at night after the surface temperature of the earwood drops. Fu ear (summer ear) is required to be harvested both big and small, because the high temperature is easy to be caused by insect pests and bacterial contamination, auricularia auricula should be harvested when the weather is sunny after rain, the ear piece is dry and the ear root is still wet.

2. Management of Lentinus edodes over summer

(1) refurbishing the mushroom shed. Corresponding management measures must be taken according to the change of air temperature, build a shade shed according to the requirements of "seven yin and three yang" in summer, create a suitable cool environment for bacterial sticks, prevent sun exposure, replenish water during drought, and adjust temperature and humidity. to ensure the robust growth and safety of Lentinus edodes mycelium through the summer.

(2) bacterial stick management. Set up the code of the bacteria stick and dig the drainage ditch to prevent the mushroom farm from accumulating water. 40-60 days before promoting mushrooms in autumn, code the mushroom wood into a "thin # word pile". Cover it with agricultural film on rainy days to prevent rain, so that the stick is gradually dry and ready for autumn.

(3) Control of Lentinus edodes gall midge

1. Agricultural measures

First, clean up the old mushroom farm thoroughly, remove the waste bacterial sticks, dead branches and leaves, burn them centrally, and transfer the mushroom sticks if possible; the new mushroom farm should be cleaned thoroughly before it can be used. Second, the new mushroom farm should be far away from the mountain forest slope and the old mushroom farm. Third, newly harvested mushroom sticks should be brushed with lime water or barbecued with bark for 3 minutes to kill insects. The fourth is to strengthen cultivation management, promote the good development of Lentinus edodes mycelium and enhance resistance.

two。 Physical prevention and cure

One is artificial culling of larvae. Second, the adults of mosquito pests have strong phototaxis, which can be trapped and killed by black light or high-pressure insecticidal lamps around the mushroom farm.

3. Chemical control

(1) mushroom farm. After cleaning the mushroom farm, you can sprinkle 4.5% cypermethrin EC 1500 times or 50% phoxim EC 1000 times.

(2) bacterial stick. The rods with pests can be killed by soaking or fumigation.

① soaking: soak the bacterial stick with 4.5% cypermethrin EC 1500 times or 20% methamphetamine EC 1200 times for 3 hours. The stick must be completely immersed in the liquid.

② fumigation: per mu of mushroom wood was fumigated with 22% dichlorvos fumigant 0.5kg for 3 days.

(3) the use of chemicals should be carried out during the summer, free period and 30 days before mushroom emergence, so as to prevent the pollution of Lentinus edodes, pay attention to the safety of drug use and prevent human and animal poisoning.
