Efficient Cultivation of Agrocybe aegerita

Agrocybe aegerita, also known as columnar head mushroom, poplar mushroom, liu mushroom, columnar ring rust umbrella. At present, there are large-scale cultivation in China, Guangdong, Fujian, and Jiangxi. The cultivation methods are divided into spring planting and autumn planting according to time. The high-yielding planting techniques are described as follows: 1. Select the improved plant species. First of all, we should choose high-yield, high-quality varieties; to ensure the quality of seed production, the original species and cultivars of the best use of wheat seeds. Appropriate production of seeds, the use of bacteria of a moderate age. Second, scientific ingredients. The following formulas are better: sawdust 40%, cottonseed husk 30%, wheat bran 18%, tea seed cake 6%, corn flour 5%, gypsum powder 1%, water content 60%. If there is no tea seed cake, the content of wheat bran and corn flour may be increased in an appropriate amount, or bean cake may be used instead. If the cottonseed hulls and sawdust can be fermented before mixing with other ingredients, it can be sterilized by bagging. With this formula conversion rate will reach 80%. Third, strict inoculation operation. First, the amount of inoculum should be increased. When the inoculum is inoculated, the strains cannot be made too crumbly to ensure the colonization of the strains. Second, inoculation should be performed before the bacterial bag is completely cooled to reduce the contamination rate. Fourth, mushroom management. During the germination period, the temperature was found to be high and should be turned over in time to avoid burning. After the cover of the mycelium was opened, the bag was opened or the ventilation was done in time to speed up the hyphae consumption. During the fruiting period, the relative humidity in the air should be ensured to meet the differentiation and growth needs of fruiting bodies. Secondly, attention should be paid to the cleanliness of the mushrooming site to prevent the occurrence of insect pests. Once the insect pests occur, pyrethrin spray can be used or a dichlorvos ball can be hung on the mushroom field. In addition, attention should be paid to ventilation to prevent bacterial bag infection and high carbon dioxide concentration to prevent the occurrence of fruit body abnormalities. Fifth, timely replenishment. Rehydration is a key step in increasing production. After the mushroom bag has finished the second tidal mushroom, the culture medium has become very dry, and it is difficult to satisfy the requirement of mushrooming, and water must be supplied. The replenishment can be done by injection method. It is better to use broth (100g of glucose, 0.05g of triacontanol, 50g of phosphorus-potassium compound fertilizer, 20g of urea, and 10000ml of water). The number of replenishment begins with the second tidal mushroom, and each replenishment of the tidal volume occurs once. China Agricultural Network Editor
