In order to achieve the best effect, the existing variety structure must be completely changed or adjusted, otherwise it will return to the dead end of seasonal production and single production. For example, in 1980s, Fujian Gutian was known as "the hometown of tremella in China", which is well known. However, Gutian people are not complacent, so they are. On the contrary, they constantly develop new varieties and markets and take advantage of their comprehensive advantages. Lentinus edodes, Agrocybe aegerita and Lentinus edodes from Jin Fu have been developed and industrialized one after another, which has enhanced the ability of edible fungi industry in this area to resist market risks, and the production of tremella has been continuously upgraded. However, some areas in the north, such as the tremella in Liangshan, Shandong Province, fell into the trough of 8 yuan per kilogram in the early 1990s because of single production and totally or mostly relying on foreign merchants to receive goods, and the tremella industry in Sheng Xing soon shrank.

Changing a single variety into a multi-variety combination, changing simple production into one-stop production, supply and marketing, and integrating agriculture, industry and commerce are undoubtedly effective measures to solve the above phenomenon. However, before selecting varieties, it is necessary to conduct extensive investigation, research and demonstration analysis on local raw materials, technology, market and production environment, so as to effectively ensure production benefits. According to the current domestic market recognition of edible fungi and consumers' consumption concept of edible fungi food, as well as local economic development and residents' income level, the domestic market and consumption can be divided into the following three categories for analysis.

① The southern market includes markets in most parts of South China and parts of East China. Due to the relatively developed economy and high income and consumption level of residents, the general consumption trend is high-grade varieties and perennial consumption, such as Pleurotus nebrodensis, Pleurotus eryngii, Pleurotus ostreatus, Agrocybe aegerita and Agaricus blazei. And the price is relatively high, generally around 20 yuan per kilogram, even reaching 50 yuan; Common varieties include white strains of Flammulina velutipes, medium-sized Coprinus comatus and small-sized white Pleurotus ostreatus. The consumption of residents is also very large. However, the quality and packaging grade of mushroom products are high, and it is necessary to supply them in time to ensure supply.

② The normal consumption of large central cities and developed coastal cities, such as Beijing as the capital, is an amazing figure. Coupled with the huge floating population, the consumption ranks first in the country. Another example is Tianjin, where the residents' concept and taste of paying attention to nutrition and health care can be comparable to those of southern cities such as Shanghai and Guangzhou. Another example is Dalian, as a developed coastal city, in addition to normal consumption, the migrant population is a huge consumer group. Similarly, this kind of market has a high consumption consciousness, and generally tends to the perennial consumption of ordinary varieties and the consumption of high-grade varieties. The main varieties are Pleurotus eryngii, Pleurotus eryngii, hypsizygus marmoreus and Agaricus blazei, while the common varieties are Flammulina velutipes, Hericium erinaceus, Lentinus edodes, Auricularia auricula, Pleurotus ostreatus and Volvariella volvacea.

(3) The market of small and medium-sized towns is restricted by economy, culture and consumption consciousness, and most of them are confined to ordinary varieties such as Pleurotus ostreatus, Flammulina velutipes (yellow strain), Volvariella volvacea, Agaricus bisporus and Coprinus comatus, and some high-grade varieties such as Pleurotus eryngii (columnar strain) and Pleurotus ferulae (columnar strain). Although Pleurotus nebrodensis, Poplar mushroom, Agaricus blazei Murill and Grifola frondosa are occasionally consumed, they can only be used as supplements.

(2) Launch a propaganda campaign to gain fame.

Due to the development of economy, the popularization of communication and the convenience of transportation, any agricultural products rarely appear "tight". Although edible fungi are international health food, the traditional thought of "good wine is not afraid of the deep alley" is no longer suitable for today's trade. Therefore, as an industrial production base, extensive publicity, appropriate publicity and "all-round" publicity in a necessary period are the basic measures for smooth product sales and stable industrial development.

(1) Value Publicity If Coprinus comatus is the leading industrial production base, the nutritional value of Coprinus comatus, especially its health care value, should be emphasized, so that people can realize the functions of this variety in treating hemorrhoids, lowering blood pressure, lowering blood sugar and improving human immunity, and then cooperate with the publicity of other auxiliary varieties.

As a modern publicity channel, online publicity is incomparable in speed, low cost and wide coverage.

(3) Conference publicity includes international and domestic academic seminars, technical exchanges, edible fungi fairs and trade fairs. And the above-mentioned regional meetings. The main work to be done is: prepare corresponding materials, including words and pictures, bring corresponding product samples, have corresponding words or pictures, and highlight their own characteristics, such as Duanmu imitation wild black fungus in Northeast China, off-season Agaricus bisporus in Shandong, and pollution-free Pleurotus ostreatus in Hebei.

(4) Media propaganda, such as TV pictures, can give the audience a direct impression, and broadcasting can give the audience an opportunity to listen and remember. The biggest advantage of newspapers and magazines is that they can be explained and introduced in detail, and can be preserved and circulated to each other for a long time.

⑤ Product promotion speaks with facts, which is immediate and clear at a glance, and makes the audience feel personally. Including: the words and patterns of product packaging; Send small packaged products or set up corresponding sites for consumers to watch or taste in person.

(3) Strict standards, quality equals life.

We have to notice that the planting methods inherited from the 20th century, especially in the aspects of ingredients, pest control, postpartum processing, etc., have outstanding product quality and safety problems. Therefore, it is necessary to carry out base construction in strict accordance with relevant international or national standards, strengthen the training of mushroom farmers' awareness of "pollution-free" goods and production technology, strictly inspect the quality, and form a system to ensure that processed products such as dried, fresh and salty edible fungi enter the market and serve on the table in a green way. Only in this way can the base production be sustainable for a long time and the stable development of edible fungi industry can be guaranteed.

(4) expand sales channels, small profits but quick turnover is the best.

Frankly speaking, at present, the technological process or technical operation of almost all conventional agricultural products is not the main problem, but the key lies in the smooth sales channels, which in turn depends on the establishment and improvement of the sales network, as in the production of edible fungi. Looking at the development of edible fungi industry and product prices, the whole is a "saddle-shaped" trajectory, and the reasons for this ups and downs are not only some man-made or natural factors, but also smooth sales channels are the main restrictive factors. The establishment of sales channels will take a long time to "imperceptibly" before it can "accumulate and develop" and further stabilize and develop.
