Due to the rapid development of the production of Agaricus bisporus, the mushroom production has soared, and the product's digestive channels are single. Therefore, the purchaser's strict requirements on the fresh mushroom (requires a diameter of 2 to 4 cm) affect the production to a great extent. Benefits and the enthusiasm of production of mushroom farmers, the mushroom planting season will be approaching, now on how to control the mushroom head size, talk about my experience. First, change strains The mushroom species commonly used in Guangxi is currently the "As2796" strain, which is a large-grained hybrid species. Its main advantages are its wide adaptability, strong resistance, large size, and high yield, but it meets the requirements of merchant acquisitions. Relatively small. If there is a contract for ordering, small-sized strains should be promptly replaced. For example, F56, F62, etc. are all small-sized varieties. Although the production of small-grained varieties is slightly lower, fresh mushrooms that meet the acquisition requirements account for a large proportion. Second, changing the thickness of the overburdened soil directly affects the size of the entity. The mechanism of action is: With the thickening of the soil, the mycelium in the soil layer is dense, but it is not easy to kink. Once the kink begins to appear, the surrounding hyphae will be supplied with nutrients and moisture, which will inevitably form a large head entity. If it is too late to change bacteria, it can be controlled by adjusting the covering layer. The normal thickness of the covering is 3 to 5 cm and can be adjusted to 2 cm. In this way, the mycelia twists and buds are densely concentrated, forming a certain degree of survival and competition, and it is not easy to form a "major mushroom." Third, the appropriate temperature mushroom temperature growth is generally between 15 °C ~ 20 °C, as appropriate to increase the temperature within the greenhouse 1 °C ~ 2 °C, can significantly increase the bud volume, growth accelerated, so that the majority of fruiting bodies The lower middle level, its mechanism of action is the same as above. Fourth, timely early mining when the visual test of fruiting bodies long to meet the requirements of the harvest, do not have to wait for seven to eight minutes to mature. Early harvesting seems to affect production, but the high rate of delivery will virtually increase the value of commodities, and it will prevent the sub-entities from fully growing up and consume too much nutrients. The output will be compensated for in increasing tides. The overall benefits are not only It will decrease, but there will be higher income.
