What are the points to note when preparing the substrate mix for tea tree mushrooms?
What should be noted in the substrate mix for tea tree mushrooms? I hope a fellow grower can give some guidance. Factors that easily lead to substandard substrate mix in the tea tree mushroom formula: the bioconversion rate of the tea tree mushroom (Agrocybe aegerita) can reach 133%, meaning that 100 kg of substrate (dry material) can produce 133 kg of fresh mushrooms. Although there are many factors behind substandard yields, one very important reason is improper culture...

Although there are many factors behind substandard yields, one very important reason is improper preparation of the culture medium.
First, one-sidedly emphasizing cost reduction and cutting the amount of wheat bran, with some wheat bran proportions accounting for only 10%, or even only 5%;
Second, the amount of lime used is the same in spring, summer, autumn and winter;
Third, mixing the substrate and bagging it before putting it on the stove takes too long, so the substrate spoils, and nutrients are destroyed.
The correct substrate mixing method for tea tree mushrooms:
The entire production cycle of tea tree mushrooms requires 10 months, and a large amount of nutrients is consumed. If nutrition cannot keep up, there is an inherent deficiency, and high yields cannot be achieved, so their nutritional needs must be met. The nutrients required by the tea tree mushroom (Agrocybe aegerita) are mainly protein. The commonly used cultivation material is cottonseed hulls, whose protein content is only 4%, while wheat bran has a protein content of 13.5%, which is more than 3 times that of cottonseed hulls. Its amino acid content is as high as 46%, and it is also a vitamin B1 additive. Therefore, wheat bran is indispensable in the formula, and the wheat bran content should be no less than 15%.
Lime serves as a pH buffer for the culture medium and also increases calcium nutrients. Its amount should be determined according to the temperature on the day of mixing: use less when the temperature is below 20°C, and more when the temperature is above 28°C. The purpose is to control the substrate from turning acidic, with an amount of 2-3%.
