Guizhou Edible Fungi: beware of misunderstandings in Edible Fungi cultivation

In the process of cultivating edible fungi, after several successes, there will often be ideological carelessness, thinking that they understand the cultivation techniques of edible fungi, and even try to change the operation in the cultivation of edible fungi. But do not know, suddenly change the operation of edible fungus cultivation, but may cause the failure of strain cultivation, and even cause serious economic losses. The following summarizes several possible mistakes in the process of planting edible fungi, which should be avoided as far as possible in the actual planting process.

1. Self-made edible fungus species: because the purchase price of edible fungi is generally high, and with the idea of increasing the benefits of edible mushroom cultivation, individual growers try to make self-made strains after planting for a period of time, but they do not know that this can easily lead to artificial reduction of production. or even cause cultivation failure. In strain cultivation, it is necessary to establish the consciousness of generation-by-generation domestication, and the selection of high-yield strain cultivation can better increase the income; at the same time, if the original seed is cultivated directly according to the inoculation operation of the cultivation bag, it will reduce the degree of sterility and produce miscellaneous bacterial infection. If the infection of miscellaneous bacteria can no longer be identified and the contaminated strains are not removed in time, the planted strains will be infected in a large area in the later stage of edible fungus growth, resulting in the failure of edible fungus cultivation and economic loss.

2. Blindly increase the culture medium nutrients in the cultivation of edible fungi: sometimes, some growers simply think that increasing the nutrition of culture materials can achieve the purpose of high yield of edible fungi, and greatly increase the content of matrix such as corn meal in the culture materials. But do not know, this will cause the phenomenon of excessive growth of hyphae, edible fungi only grow hyphae but it is difficult to form mushroom buds, resulting in a decline in production.

3, do not pay attention to ingredient mixing, fertilizer distribution is uneven: in the allocation of edible fungus cultivation fertilizer, for convenience, some people say that a handful of fertilizer is simply sprinkled into the ingredients. However, it is not known that because the fertilizer is granular, it often fails to dissolve immediately, resulting in uneven fertilizer distribution and affecting the growth of bacteria.

4. Do not pay attention to the aseptic conditions during inoculation: when making edible fungus nutrients, some people will adopt the form of clinker, and think that the nutrients have been thoroughly sterilized and can be put to the aseptic requirements at the time of inoculation. However, I do not know that in some places with more miscellaneous bacteria, both ends or damaged parts of the bag are easy to be infected with external miscellaneous bacteria, resulting in a reduction in the rate of finished products of edible mushroom bags, and then reduce production.

5. Neglect of management after inoculation: some mushroom farmers think that they have done a good job after completing the inoculation of edible fungi, and that they can let the hyphae grow on their own without too much management, but they do not know that this idea is very wrong. At the initial stage of inoculation, the indoor temperature is relatively low, and it will also cause poplar acidification if it is easy to breed miscellaneous bacteria. In addition, if the temperature in the bacteria room is too high or the bag is not turned in time, the root type may cause the consequence of burning fungus. The cultivation of edible fungi fell short of success.

6. no matter whether it is suitable for the local situation or not, blindly borrow the "high-yield" technology: for example, in autumn and winter, wall cultivation techniques are often used to cultivate edible fungi in Guanzhong, Shaanxi Province. After knowing this, mushroom farmers in other places think that the use of wall soil mulching technology will certainly increase the yield, but they do not know that if this method is adopted in spring and summer, it is very likely to cause the growth of burning bacteria or actinomycetes that like high temperature, resulting in a reduction in the production of cultivated edible fungi.
