The technique of aphid grass-breeding has been widely disseminated throughout the country. In the north, the main method is solar-green room shelfing, while in the south it is mostly indoor factory production and managed with artificial intelligence. My country, liaoning, shandong, henan, prefers rice and wheat. Pyrotechnics are used, while corrosives are used as whole-grass cultivation as surrogate hosts in jilin, jiangsu and zhejiang。
We're going to give you a detailed description of the planting process. The first is the preparation of bacteria, which is the key to the whole cultivation process. Care must be taken in the selection of bacteria, as aphid herbs are degraded more rapidly, which can lead to instability in cultivation. It is therefore recommended that parent species be purchased from authoritative research institutions and that blind expansion be avoided, including through the separation of sub-entity organizations。
And then we'll have the fungus preparation. The selection of high-quality, pure, robust and age-appropriate bacteria is essential and directly affects the high productivity and quality of herb. When tissue is separated, appropriate tissue blocks should be removed from the gestationary part of the child entity to obtain a good strain. At the same time, attention should be paid to the freshness of the strains to ensure that the husks are produced normally and have high yields。
And finally, let's find out about liquid bacterial inoculation techniques. It's a common method of mackerel cultivation. Fresh liquid culture fluids should be prepared before vaccination, and their formulations have an important impact on the growth and production of bacteria. Through careful operation, we can successfully inoculate liquid bacteria into the culture base and thus begin the journey of herb cultivation。
(1) 2 per cent corn powder, 2 per cent glucose, 1 per cent protein, 5 per cent yeast powder, 1 per cent potassium phosphate, 0. 5 per cent magnesium sulphate and 5 ph。
(2) the other formulation is 20 per cent potatoes, 3 per cent corn powder, 2 per cent glucose, 3 per cent protein, 15 per cent potassium phosphate and 0. 5 per cent magnesium sulphate, with ph also controlled at 5。
(3) in addition, 1 per cent glucose, 1 per cent protein, 1 per cent silk powder, 2 per cent milk powder and 15 per cent potassium phosphate, with ph of the same value of 5。
In a triangle of 500 ml, the amount of liquid should be kept between 200300 ml. It was then sterilized at 121°c for 20 minutes under 105 mpa pressure. Upon the end of the sterilization, 710 lumps of mother species of approximately green bean grains were connected to each bottle of culture fluid for a period of 12 hours. After that, a magnetic mixer was used to mix it 24 hours at 1,000 r/min and then placed on a rocking bed, which was browsing at 130140 r/min, lasting 2123 °c until after two to three days, again at 1,000 r/min. At this point, there are a large number of fungus ball sizes like small grains of rice in well-bred liquid species, and the culture fluid becomes clear and emitters a rich fragrance。
With regard to the planting season for herbicides, the fungus is of a medium- and low-temperature type and can be cultivated for two seasons a year under natural conditions. Cultivation in the spring usually takes place in february-march, when the temperature is low and it is appropriate to cultivate myceloids through heating. By april-may, natural temperatures had returned to about 20°c and air moisture was relatively high, which was a good season for sub-season growth. Autumn cultivation, on the other hand, has been chosen to start in july-august, with grass in september-october. Cultivation can be carried out over four seasons if it is indoor and has a manual control environment。
As for the formulation of the culture base, the planting of the herbicide grasshoppers is mainly based on silk or wheat. At present, it is more common to use rice or wheat as the primary feedstock. For example, in 750 ml canisters, 30 g wheat is bottled with 50 ml nutrient when wheat is the main ingredient, while 30 g rice is bottled with 40 ml nutrient. For 500 ml, the volume of bottled bottles is reduced accordingly。
The nutrient formulations are as follows:
(1) glucose 10g, protein 10g, potassium dihydrophosphate 2g, magnesium sulphate 1g, ammonium lemonate 1g, added to vitamin (b1) 10 mg, with full mixing, with water recharge up to 1000 ml, maintaining ph at around 7。
(2) another option is to use 200 g potatoes to boil the slag and then add sugar 20 g cane, milk powder 1520 g, potassium dihydrophosphate 2g and magnesium sulphate 1g in the leachate, with the same additional water to 1000 ml and ph to be controlled within 78 m。
(3) in addition, glucose 10g, protein 10g, potassium dihydrophosphate 2g, ammonium lemonate 1g and magnesium sulphate 5g may be selected to be added to vitamin (b1) 10 mg, also supplemented by water up to 1000 ml to make the appropriate culture base。
In the process of production, the following points need to be noted: first, to ensure that the ratio of primary to nutrients is moderate to obtain the appropriate water content, usually between 57 per cent and 65 per cent; secondly, to strictly control the ph value of the culture base within 52; in addition, it is not appropriate to impregnate the main ingredient and nutrients for too long, usually not longer than 5 hours, before sterilization, in order to prevent the cultivation of fermentation and sugar; and lastly, in the case of the application of normal volatilism, the temperature within the stove must be 100°c within three hours in order to avoid the degradation of the base acid。
Once these steps have been completed, bottled (boxes) may be performed. Select the canister or plastic bottle (box) as a planting container, filling the culture base to 1/4 ~1/3 deep in the bottle (box) and pouring it into an appropriate amount of nutrient. Polypropylene plastic sheeting is sealed prior to sterilization。
Then we're going to have a sterile treatment. High pressure sterilization is generally recommended at 128 °c for 5 hours at 147 mpa pressure. Alternatively, a 10-hour application at 100 °c is used. After sterilisation, to ensure a uniform water content on and below the culture base, there is a gap between the grains and no paste。
The last step is vaccination. Inoculation is carried out under sterile conditions when the culture base cools to below 30°c. For planting containers of 500 ml, 10 g of solid species or 10 ml of liquid species may be vaccinated. So, the production process of a cultured herb。
