Dictyophora dictyophora is a precious edible fungus. Because of its high price, more and more people began to plant it.

1, temperature

To plant dictyophora indusiata, we must first grasp the temperature. Dictyophora dictyophora is a typical mesophilic fungus. During the growth period of fungi, hyphae can grow at 6℃-27℃, but the optimum temperature is 65 08℃-24℃. When the temperature is lower than 15℃ or higher than 35℃, the mycelium grows slowly or stops growing.

Dictyophora dictyophora can grow at the temperature of 65438 08℃-30℃ during the fruiting period and fruiting body growth period, and the optimum temperature is 23℃. If the temperature is lower than 13℃, the growth of fruiting body cannot be hindered. When the temperature is higher than 30℃, the growth of fruiting body will slow down, and when it is higher than 35℃, the growth of fruiting body will stop.

When cultivating dictyophora indusiata, we must choose the planting time according to the local climate environment, and we can also adjust the temperature according to the climate change when planting.

Step 2 apply fertilizer

Fertilization, including nutrient components of culture materials and late topdressing, Dictyophora indusiata initially grows on rotten bamboo leaves or bamboo whips. As a rare edible fungus, it has a high demand for nutrients. There must be bamboo raw materials in the culture medium for planting dictyophora.

When planting, put bamboo stalks, branches, leaves and roots into fertile soil in advance to rot, and then add phosphate fertilizer and potash fertilizer to mix before planting. These bamboos can also be mixed with rice straw, sawdust and rice bran to form cultivation materials for planting.

In the later stage, topdressing is mainly to apply some nutrient solution. After a batch of Dictyophora dictyophora was harvested, it was irrigated with nutrient solution made of urea and potassium dihydrogen phosphate. When topdressing, it should not be directly poured on the fruiting body of Dictyophora indusiata to avoid the rot of infected bacteria.

Measures to ensure high yield of dictyophora indusiata;

I. Requirements for culture materials

1, the materials should be sufficient.

Use 3000~4000 Jin (dry material) per 667 square meters, which is the basis of high yield. Mushrooms can grow normally even if they are fed less, and the production cycle is short, which can improve the land utilization rate. However, it is almost impossible to achieve high yield under the condition of insufficient culture materials.

Step 2 use a mixture

At present, many mushroom farmers cultivate dictyophora indusiata with rice husk, and its yield is often low. Taking chaff as the main planting material, we can consider adding wood chips, flowers, bamboo chips, bamboo wool and other raw materials with high lignin content.

3. Increase the nitrogen content in the culture medium.

Insufficient ammonia is one of the important factors of low yield of dictyophora indusiata. Increasing nitrogen source in culture medium is an effective measure to increase the yield of dictyophora indusiata. The specific method is to add cow dung, chicken manure, duck manure or urea to the culture medium.

But the medium to which these substances are added must be fermented. Urea should be added separately, and the addition amount should not exceed 1.5% of the total weight of 0/000 parts of materials, and livestock manure should be added separately, and the addition amount should not exceed 20% of the total weight of 0/000 parts of materials.

Livestock manure and urea can also be added at the same time, but the proportion should be strictly controlled and cannot exceed the standard. In addition, about 65438 0% calcium carbonate or gypsum powder should be added in the fermentation process.

Second, change raw materials into fermented materials.

Planting fermentation medium is more conducive to the decomposition of Dictyophora dictyophora mycelium and can promote the accumulation of nutrients in mycelium, thus increasing the yield. The same fermentation process can also kill various pests such as mites and some competitive miscellaneous bacteria in the culture material to ensure the normal growth of hyphae.

In particular, the culture materials added with livestock manure and urea must be fermented. Otherwise, if the ammonia content in the culture medium is too high, the mycelium will become thinner, weaker and even die. The fermentation method can refer to the mushroom fermentation process.

Generally, it is fermented for 30-40 days. After fermentation, make sure that the culture material has no ammonia smell before sowing.

Third, improve the quality of covering soil.

Practice has proved that the growth of dictyophora indusiata fruiting body is closely related to soil covering. Without mulch, Dictyophora dictyophora can't grow even if its mycelium grows well, and the quality of mulch has a great influence on the yield.

It is best to choose loam with high humus content as covering soil for planting dictyophora indusiata. Humus contains a variety of nutrients needed for the growth of Dictyophora dictyophora, and also has the functions of loosening clay, fixing sand and promoting the formation of soil aggregate structure.

Therefore, if the planting site is covered with soil in situ, we must pay attention to the soil quality of the site when selecting the site. If you can't find a site with good soil quality, it's best to cover it with humus or burn some burnt soil, then pour some people's feces and leave it for a while before covering it.

Fourth, management should be cautious.

In order to obtain high quality and high yield of dictyophora indusiata, management should focus on the following points. The first is humidity management. For the cultivation of dictyophora indusiata, humidity management includes three aspects: the humidity of culture material, the humidity of covering soil and the relative humidity of air.

In the spawning stage, it is necessary to control the humidity of the culture medium to promote the normal growth of mycelium and lay the foundation for high yield. Theoretically, the water content of the culture material is 60%~65%, but in practice, as long as the humidity of the culture material is enough, it can be extruded by hand without adding water.

Don't let the rain shower for a long time before the mycelium is full of culture material, and it is not suitable to soak in the furrow for a long time. In the later period of fungus sprouting and fruiting, we should pay attention to the humidity of the covering soil, so as to promote hyphae to enter the soil, form fungus cords, and then grow dictyophora.

Under normal circumstances, when the soil particles are pinched by hand, the soil moisture is controlled to be flat but not sticky. During the fruit-bearing period, we should focus on controlling the relative humidity of the air in the border.

Generally, it is not watered in rainy days, and it should be watered in the border for continuous sunny days. But when the temperature is below 25℃, the number of water sprays should be less and the amount should be sufficient; When the temperature is higher than 30℃, a small amount of water should be sprayed several times. Followed by temperature management.

The cultivation of Dictyophora dictyophora is mainly through reasonable arrangement of seasons and growth and development at natural temperature. Temperature management should pay attention to the following points: first, if sowing in low temperature season, cover the border with a layer of straw and film to keep the temperature of the culture material above 65438 05℃.

Second, in hot weather, it is necessary to shade the sun in time to prevent strains or hyphae from being sunburned; Third, in the fruiting stage, in case of high temperature weather, the sunshade should be thickened to prevent the mushroom buds from shrinking and dying due to high temperature.
