How to Make Maitake High Yield


Water management: In late April, when the natural temperature reaches above 15°C, water should be poured once in the border. The amount of water should be about 2 cm without the border surface. The ground is suitable, and try to spray to the space. According to the rainfall situation, it should be watered once every 5 to 7 days during the drought, and it is advisable for the water to seep immediately, and less irrigation when there is rainfall. After the original base of Grifola frondosa grows, you should pay attention to keeping away from the original base when spraying water, so as to avoid washing away the yellow water drops on the original base. After Grifola frondosa grows up, water can be sprayed on the mushroom to promote the growth of the mushroom body. For 3 days after harvesting, the roots of Grifola frondosa should not be sprayed with water, so as to facilitate the rejuvenation of the hyphae and the growth of damp mushrooms. In the high temperature season, it is also necessary to sprinkle water on the straw curtains and the open space outside the pit to cool down and increase humidity. It is best to use warm water that has been exposed to sunlight when spraying and irrigation in low temperature seasons to facilitate heat preservation. In the rainy season, when there is sufficient rainfall, less water can be sprayed or no water can be sprayed. If it is dry and hot, it is necessary to spray a large amount of water at noon during the day.

Temperature management: In late April or early May, heat preservation is the main focus. At night, straw curtains and plastic sheets should be covered tightly, or straw curtains should be placed underneath and plastic sheets should be placed on top, and the time for direct sunlight to the border should be extended appropriately when there is sufficient sunlight. The high temperature and high heat period from late June to August should be mainly to cool down. You can use water spray to cool down and increase the mulch on the grass screen to increase the degree of shade. At night, the plastic sheet or straw curtain is uncovered to grow in the open air, and the grass curtain or plastic sheet is covered again when the temperature is high during the day.

Ventilation management: After mid-April, the plastic cloth on the north side should be rolled up and stacked on the straw curtains to keep the north side ventilated for a long time. The straw curtains should be opened for 1 to 2 hours every morning and evening. Pay attention to less ventilation in low temperature and windy weather, more ventilation in high temperature and rainy weather, and increase ventilation appropriately before and after spraying large water in the morning and evening. Ventilation should be carried out in harmony with heat preservation, moisture retention, and shading. It must be ventilated or over ventilated. During the differentiation period of mushroom buds, there is less ventilation and more moisture retention, while during the growth period of mushroom buds, more ventilation is used to promote evaporation.

Illumination management: Keep the stable scattered light for the growth of Grifola frondosa with the method of supporting inclined frames, and increase the weak direct light in the sun every morning and evening for 1 to 2 hours. In production, do not use too thick straw curtains to retain sparse direct light, avoid strong direct light during the fruiting period, and do not remove shades for heat preservation and easy operation, resulting in strong light mushrooms.

Coordinated management of light, temperature, water and air: factors such as light, temperature, water, and air must be coordinated. In different seasons, different periods, different weather conditions, and cultivation management conditions, the main aspects should be grasped, but they should not be ignored so as to deviate from the secondary The limit of the aspect also needs to create demand conditions for other factors through the profile measures of any one factor. For example, increase ventilation in rainy days to achieve the moist conditions for fruiting, and reduce high temperature damage by increasing shading in dry heat; open the curtain every morning and evening to dry, and can be carried out at the same time as ventilation and water spraying, or mushrooms can be harvested at this time.

Grifola frondosa deformed mushrooms are mostly caused by uncoordinated environment, such as primordium yellowing, wilting and non-differentiation, due to high ventilation and low humidity; small scattered mushrooms are caused by lack of ventilation and lack of light; mushroom caps are shaped like leaflets, and differentiation is slow Staghorn mushrooms and tall mushrooms are caused by poor ventilation and excessive humidity; yellow swollen mushrooms are caused by large water vapor, weak ventilation or high temperature; albino mushrooms are mostly caused by weak light; scorched mushrooms are caused by low light intensity and moisture ; The primordium does not grow, mostly due to the thick soil, watering too often, and cold water, resulting in low temperature and slow growth; thin meat mushrooms are caused by high temperature, high humidity, poor ventilation, and the mushroom body does not evaporate; the culture medium collapses It is caused by the death of mycelium due to high temperature and lack of ventilation.

In short, the premise of high yield of Grifola frondosa is to coordinate light, temperature, water and air factors to create conditions suitable for growth and development.
