Excellent varieties are the basis and key to the production of tea tree mushrooms with high quality and high efficiency. At present, the market of tea tree mushroom strains is relatively disordered, and the phenomenon of homonymy and heterogeneity is serious. When cultivators choose cultivated varieties, it is recommended to choose from the following aspects:
(1) Purchase from a strain institution with better qualifications
The strain institutions with better qualifications generally have strain numbers and strain names. The strains they sell have been approved by long-term field tests and relevant state departments, and the source of strains and the quality of strains are guaranteed.
(2) Pay attention to the transportation process
During the transportation process of bacteria purchase, you need to pay attention to weather, temperature, packaging and other issues. The hot weather can easily lead to high temperature burning of bacteria, which will seriously cause the death of bacteria and cause huge losses. During the transportation process, strict attention should be paid and the transportation temperature should be controlled below 30 °C; It is well isolated from the outside world to prevent miscellaneous bacteria from invading the inside of the bacteria.
(3) Observe the health of the mycelium
Robust hyphae are generally thick white, dense, uniform, and have strong vitality. If the mycelium is sparse, uneven, aging, variegated spots or antagonistic lines, it must not be used as a cultivar.
(4) Carefully select new varieties
Common cultivars are generally produced and cultivated for many years, their characters are relatively stable, and they are suitable for habitual management experience. For new varieties, it is necessary to know the characteristics of the varieties, suitable cultivation areas, cultivation substrate formulations, temperature types and other information, and conduct larger-scale production after introduction and completion of fruiting experiments and uation.
Cultivation material formula
In production, cottonseed husks, sawdust, corncob, etc. are the main materials, and wheat bran, corn flour, tea seed cake, brown sugar, lime, gypsum, etc. are the auxiliary materials. The optional formulas are as follows:
(1) Cottonseed hull 82%, wheat bran 16%, lime 2%.
(2) Cottonseed husk 78%, wheat bran 20%, gypsum 1%, lime 0.5%, sucrose 0.5%.
(3) 45% cottonseed husk, 40% corncob (under 10 mm), 13% wheat bran, 2% lime.
After inoculation, the bacteria sticks were moved into the bacteria room for bacteria management. During the germinative period, attention should be paid to controlling temperature, humidity, light and carbon dioxide.
Air temperature: The ambient temperature should be controlled at 20-27°C during the germ-infestation period.
Air humidity: The air humidity during the germ-forming period should be controlled at 60% to 70%.
Light intensity: The tea tree mushroom mycelium does not need light during the growth process, and the light will inhibit the growth of the mycelium. Therefore, it is necessary to maintain a completely dark and non-light growing environment throughout the growth period.
Carbon dioxide: The carbon dioxide concentration is controlled at 0.2%~0.4% throughout the germ cycle.
There are three criteria for physiological maturity. The first is the age of the bacteria in a suitable temperature environment, about 60 to 80 days; the second is that the color of the mycelium is thick white, the growth is vigorous, and some bacteria sticks begin to spit yellow water;The third is that the bacteria sticks become hard and elastic, and the quality is reduced by about 20% compared with the time of inoculation. After physiological maturity, it will be transferred to fruiting management.
