Why is the mortality rate of morels in the seedling stage so high?

The seedling stage of morel mushrooms is still very delicate. If the humidity is not suitable, or if the temperature is high and humid, the morel will rot. In addition, if there are pests and diseases or if the light is not suitable, it will also cause its death.

Because of the temperature, the seedling stage is very fragile, we must maintain the right temperature, as well as the right light, the humidity of the soil also needs to be very strict, to be managed in accordance with the scientific breeding.

First, it is caused by excessive humidity or too little, second, it may be caused by high temperature and high humidity, third, it can be caused by pests and diseases, and fourth, it is caused by light and field management. You have to pay attention to what causes it.

Because the probability of morel infection during the vaccine is very high, and once such morel is infected with the disease, there is no hope of **.

Because the seedlings are susceptible to pests and diseases, coupled with the lack of timely absorption of nutrients and lack of adaptation to the environment, it will cause a high mortality rate.

Because such bacteria are particularly virulent and do not have any resistance at the seedling stage, the mortality rate is particularly high.

Summary. The temperature range for the growth of morel mycelium is generally , and the appropriate temperature for spore germination is ; Fruiting bodies can grow in , but they grow best in the temperature range. Morel mushroom is a low-temperature type of fungus, in the early stage of growth, the underground mycelium begins to grow, the mushroom is in March to April, but if the temperature exceeds, the daily growth rate of mycelium will turn sharply.

At temperature, the growth rate of mycelium is the fastest, but the layer of fungi is relatively thin and easy to age. The average annual temperature in the valley is very suitable for the growth of morels, which is very suitable for the growth of morels, even if there is abnormal temperature, the growth environment can be optimized through artificial planting, and the yield of artificial cultivation of morels can be improved.

The temperature range for the growth of morel mycelium is generally , and the appropriate temperature for spore germination is ; Fruiting bodies can grow in , but they grow best in the temperature range. Morel mushroom is a low-temperature type of fungus, in the early stage of growth, the underground mycelium begins to grow, the mushroom emerges in March-April, but if the temperature exceeds, the growth rate of the mycelium will turn sharply on the day of the encounter. At temperature, the growth rate of mycelium is the fastest, but the layer of fungi is relatively thin and easy to age.

The average annual temperature in the river valley is very suitable for the growth of morels, which are cool-loving species, and even if there is an abnormal temperature, the hereditary environment can be optimized through artificial planting to improve the yield of artificial cultivation of morels.

The morel mycelium will freeze to death, and the morel belongs to the low-temperature type of modified fungi, and the temperature is below 0 and will not grow. If the temperature is too low or too high, it may lead to the mycelium of morels can not survive, if you want the mycelium of morels to grow normally, you should pay attention to the temperature of the sowing environment should not exceed 20, and the ground temperature is best maintained at 10-16. Morel mushrooms in the mushroom period to pay attention to the control of the temperature of the disturbance, pay attention to the light, generally three points of yang slow annihilation Li Guang seven points of yin is the best, when the mushroom emerges, to ensure the soil moisture content.

Summary. Dear, hello, I am the answer is honored to answer for you, the biggest harm is afraid of morel mushroom stubble, which will cause sparse mycelium, slow germination, easy to be infected with Fusarium, blackfoot, arachniosis and other miscellaneous fungi and insect pests during mushroom emergence, sometimes the yield is reduced by more than half, and even the harvest will be lost. How to solve the hazards of heavy stubble disinfection If it is a plastic greenhouse, the disinfection treatment of the inner wall of the greenhouse, the shed film, facilities and other equipment, increase the humidity to more than 70%, induce the germination of miscellaneous bacteria and harmful microbial spores, use bacteria to eliminate fumigation and disinfection, once every 3-5 days, 2-3 times in a row, and the old shed becomes a new shed!

Combined with high temperature stuffy shed, the effect is better! Secondly, the disinfection of the soil, after the planting of morels, water thoroughly on the morel residues, and spray compound probiotics + chelated trace elements + chelated traditional Chinese medicine + biological insect control products, two days later, water the soil in the greenhouse to make the depth reach about 15 cm, and then carry out high temperature stuffy shed for 7-15 days. Old plots become new plots!

If it is a flat shed, 20 days before the morel mushroom is sown, the pesticide phosphine (refer to the instructions for dosage) is scattered on the surface of the soil, and then rotary tillage is carried out to kill pests in the soil. When planting morels, the use of Yifuyuan mushroom ecological treasure flushing, 5-10 kg per mu, can not only improve the yield, but also play a role in preventing heavy stubble obstacles.

Morel is a low-temperature and high-humidity fungus, most of which grow in chalky soil or limestone, and occur in humus soil, black-yellow loam soil, and sand-mud mixed soil. Among them, the rock ash and charred wood of apple trees are the best nutrients for morels, which prefer to grow in burned areas and old apple orchards.

<> morel mushroom is a high-humidity fungus, which likes shade, and has a variety of soil environment and vegetation types required for growth, and generally produces mushrooms at the turn of spring and summer, and its yield is directly related to rainfall. So, how many low-temperature levels of morels freeze to death?

Morel mushrooms may freeze to death at a low temperature of 0 degrees. The suitable temperature of the hyphae is 18-22 degrees, the suitable temperature for spore germination is 18-22 degrees, and the fruiting body of the letter punch is 10-20 degrees. In addition, sufficient oxygen is one of the essential and important conditions for the growth and development of morels.

Morel mushrooms freeze to death at minus 38 degrees Celsius. The mycelium will be damaged by He Ming in a low temperature environment, but the sclerotia resistance is relatively good and it is not easy to freeze to death, minus 38 generally will not freeze to death noisy bacteria, but it will be frostbitten, and below minus 38 will cause morels to freeze to death.

Growing environmentMorel mushrooms generally grow from low-altitude plain areas to 3,200 meters above sea level. It mostly grows on the humus layer of broad-leaved forests or mixed coniferous and broad-leaved forests. It mainly grows in sandy loam soil rich in humus or brown soil, brown soil, etc.

Morel mushrooms grow more easily on burned forest floors.

Morel mushrooms are generally easy to germinate fruiting bodies under low temperature and high humidity conditions, so the growing season of wild morel fruiting bodies is generally in March-May or August-September every year. Studies have shown that the conditions for the occurrence of morels in the wild mainly depend on the precipitation in November of the previous year, and the occurrence of morels in the current year depends on whether the temperature of the 5 cm surface soil in the spring of the current year is stable. Therefore, the occurrence period of morel mushroom is affected by the annual climatic conditions, and is closely related to the temperature, rainfall and rainfall time in the area where it occurs.

In general, morels tend to occur in environments where the soil is moist or rainfall is high and easily moisturized, or the water table is high. Light has a certain role in promoting the formation of fruiting bodies, and the growth and development of fruiting bodies has phototaxis. Adequate oxygen and a well-ventilated place are necessary conditions for the normal growth and development of morels.
