Synthetic Techniques for Edible Fungus Cultivation by Substituting Grains with Grass

I. Overview

The mushroom, fungus and other edible mushroom cultivation around the world are mainly used for cultivation materials such as forest trees, wheat husks and rice bran, and the cultivation period of the forest tree raw materials is long, which restricts the large-scale development of the bacteria industry.

In the present invention, wild and artificially cultivated grasses rich in resources are used in place of forest trees, wheat husks and rice bran to cultivate edible fungi and medicinal fungi, and wastes of edible fungi and medicinal fungi are used to produce high-quality high-protein feeds. It breaks the boundary between the traditional woody bacteria and grassy bacteria in concept, and breaks through the boundary of bacteria, grass, animal husbandry and other disciplines. It is a great change in the cultivation of edible fungi, and it has opened up a new generation of edible fungi and medicinal cultivation materials, which is conducive to the vigorous development of the bacteria industry and conducive to the protection of the ecological environment. The three major economic, social, and ecological benefits of bacterial production are organically combined. So far, 27 kinds of fungus can be used to cultivate 38 species of edible fungi and medicinal fungi. This is the most economical way for humans to obtain mushroom health foods and provide high-quality bacterial protein feeds for livestock. This is a comprehensive new technology pioneered by the international community with strong practicality, wide application scope, high economic benefits and good ecological benefits.

Second, the main content

(a) concept

1. Fungi: Suitable for cultivation of edible fungi; Medicinal plants such as weeds, pastures, and seaweed are commonly called grasses.

2. Germplasm technology: the use of solar energy to synthesize grass, and then use grass cultivation of edible fungi, medicinal bacteria, culture of bacterial protein feed comprehensive technology referred to as grass technology.

(II) Main technical content

Since 1983, researches on grass and grass technology have been carried out. Now we have screened, planted, managed, harvested, and processed the grasses and grasses, and cultivated edible fungi, strains of medicinal bacteria, breeding strains, cultivation techniques, and bacteria. The systematic research on the protein feed production technology and other aspects has formed a mature supporting new technology that can be applied on a large scale in production. The main contents are as follows:

1. Screening of grasses and grasses: The research has found that 27 kinds of high-yield and high-quality grasses can be used to cultivate edible fungi instead of forest resources.

Most of these cultivars have nine advantages: nutrient-rich, high yield, perennial, strong regeneration ability, high plant height, wide distribution, strong adaptability, easy artificial cultivation and management, and abundant existing resources. It is a good culture medium for edible mushrooms. The nutrition of these grasses is richer than that of wood chips, and the nutrition structure is also more reasonable. The contents of protein, nitrogen, fat, phosphorus, potassium, and magnesium are all higher than that of wood chips. Among them, wild moor, genus reed, swamp and reed The protein content of the ramie and ramie is 237-361% of the mixed wood chips, 191-303% of the mixed wood containing magnesium, 101-216% of the wood containing fat, and 232-353% of the mixed wood containing nitrogen. , Phosphorus is 225-685% of the mixed wood chips, and 346-908% of the mixed wood contains potassium.

2. It was found for the first time that 38 species of edible fungi and medicinal fungi were cultivated using the above-mentioned fungi.

3. It was found for the first time that DN2 mycelial proteins with high fecundity and high protein content could be used instead of wheat husks, rice bran to cultivate shiitake mushrooms, fungus and other edible fungi. Open up a new way of growing the nitrogen nutrition needed for edible fungus.

4. To study the high-yield and stable yield cultivation techniques for edible mushrooms such as shiitake mushrooms, fungus, and mushroom, which are compatible with the nutrition, nutritional structure and physical characteristics of the grass.

5. Sorghum substitutes for the generation of wood to cultivate mushrooms, fur auricularia, black fungus, shield fungus, bamboo worm, fungus and other edible mushroom technology.

6. Fungus grass fermentation cultivation of mushrooms, hair fungus, black fungus, mushroom, Hericium, Ganoderma lucidum and other edible mushroom technology.

7. The annual outdoor mushroom cultivation technology.

8. The annual cultivation of edible fungus at the factory.

9. Grass grass cultivation mushroom technology.

10. The artificial cultivation and management techniques of fungus grass.

11. The manufacturing technology of the grass grinder.

12. Straw cultivation of mushrooms, oyster mushrooms, mushroom, hair fungus and other edible fungus waste bacteria production of protein feed technology.

13. Straw culture cultivation of edible fungi fertilizer application technology.

Third, the application of broad

(I) Application

This technology was listed by the National Science and Technology Commission as one of the twelve major agricultural starlight projects of the state in 1991. It has been proved that the cultivation of edible fungus in grassland is low in input, high in output, short in period, quick in efficiency, and high in economic efficiency. Good "short, flat, fast" project with good ecological benefits.

(B) The main advantages, characteristics:

The application practice shows that the cultivation of edible fungi with grass and grass has more than eight advantages compared to conventional methods for the cultivation of wood and sawdust:

1. Help protect the ecological environment. "Using grass to replace the wood" cultivation of edible fungi, to achieve a major change in the raw materials for the production of edible fungi, and fundamentally solved the "bacterial forest conflict" between edible fungi production and forestry ecological balance.

2. Change the weeds for the delicacy, change the waste into treasure, and change the damage to benefit. Developed and utilized the most abundant grassland resources in the world.

3. Cultivation of edible mushrooms with grass and fungi. Relieve the contradiction between edible fungus production and animal husbandry for grain.

4. High solar and biological conversion rates. Under the natural conditions of light, humidity, and heat in Fujian, the conversion rate of solar energy into grass is 4-6 times that of broad-leaved trees, and the biological efficiency of the cultivation of edible grasses in Yincao is 20-40% higher than that of mixed-wood cultivation. And the cost is reduced by more than 20%.

5. Good quality. The cultivation of mushrooms, fungus and other edible fungi such as mushrooms, fungus, and other nutrients such as nitrogen, phosphorus, and potassium are more important than the cultivation of swarf and wood. Heavy metals such as mercury, cadmium, lead, and arsenic are all within the allowable range of relevant international regulations.

6. The cycle is short. Among them, the whole growth period of the cultivated shiitake mushrooms was shorter than that of sawdust cultivation by three weeks. The bamboo shoots cultured with the grass and grasses were mushroomed two months earlier than the wood chips cultivation.

7. The raw material is cultivated quickly and the yield is high. Planting in the spring can be used in the autumn, and only the broad-leaved trees can be cultivated for six to twenty minutes, and one-time planting can be done for many years. Such as grass, in the first year of artificial cultivation in the south of China can produce 4-5 tons of hay powder, and can be cut for many years.

8. The three major economic, social and ecological benefits are combined organically, and resources can be comprehensively utilized to form a virtuous cycle. In the soil erosion area, weeds, soil conservation, cultivation, and waste materials are used as fertilizers to form grasses - soil - bacteria - and benign fertility. In the pastoral area, a benign cycle of grass, bacteria, pasture and manure can be formed, which is conducive to achieving a virtuous circle of plants, fungi, and animals.

(c) Strong practicality and wide application range.

It can be produced on a small scale and on a large scale. It is suitable for both rural and industrial production. It can be applied in most countries in the world and in the border areas. Any herbaceous grass such as Manghi, Ashcroft, Prunus armandi, and Phragmites communis, there are pasture areas such as grassy grass and broadleaf gar, and they can be used in planting corn, sorghum, and wheat.
