How to grow straw mushrooms with sawdust – Complete and effective instructions right from the first time

The trend of growing mushrooms at home is increasingly popular, instead of having to buy straw mushrooms from the market with concerns about food hygiene and safety and uncertain quality. In this context, GREEN MECH wants to share how to grow straw mushrooms with sawdust – a simple and effective method.

How to grow straw mushrooms with sawdust is done through the following steps

Prepare materials

To start the process of growing straw mushrooms using sawdust, choose special sawdust that ensures three “3 NO” criteria: no mold, no essential oils, and no toxins such as chemicals or gasoline.

Next, put the sawdust into a humid environment to reach 70% hydrolysis. Then, compost the sawdust into piles, each pile weighing about 300kg. The composting process lasts 4 to 6 days, with the pile turning every 2-3 days. The composting process helps stimulate the growth of actinomycetes, enhances the decomposition of sawdust and creates favorable conditions for fungi.

To optimize harvest yield, you can add organic fertilizers such as manure and plant matter to your sawdust pile. Note that the rate of adding organic fertilizer should not exceed 20% of the compost pile volume. At the same time, about 1% mineral supplementation is needed to provide enough nutrients for mushroom growth.

Add nutrients to sawdust

Adding nutrients to sawdust is an important step to optimize the quality of the incubation environment and improve performance in the mushroom growing process. This method includes adding nutrients from organic, inorganic and mineral fertilizers.

When using organic fertilizers such as manure or compost from plant remains, it should not exceed 20% of the compost pile’s volume. Inorganic fertilizers such as urea, DaP, SA, NPK are also added, with the amount adjusted so that the mushrooms receive the correct nutritional needs without causing excess or deficiency. Adding minerals such as ash to the compost pile at around 1% helps ensure mushrooms have enough minerals needed for healthy growth. This not only creates an ideal incubation environment but also ensures the quality and safety of the mushroom product.

Choose a planting location

Choosing a mushroom growing location is an important step in the growing process. Choose a clean, flat and high area, avoid places at risk of flooding. Growing mushrooms outdoors is also a viable option, however, it is necessary to avoid livestock areas and places containing wastewater or household waste. Before planting, it is important to clean up trash and grass in the land area and spread lime to kill bacteria.

Sow seeds

Preparing spawn is an important step, ensuring they are good, of the right age and free of bacterial contamination. The quality of spawn greatly affects the yield and quality of mushrooms. The spawn bag needs to meet the criteria such as white mushroom mycelium, pink speckles, and when opening the bag, it emits the characteristic aroma of straw mushrooms. On average, each bag of spawn weighs about 120g.

Nursery seedling sawdust bags

After the sawdust bags have been transplanted, farmers move them into the nursery with a stable temperature of about 24 – 26 degrees Celsius. The nursery needs to be designed to be clean, airy and without light to create dark conditions. optimal for fungal growth. The trellis system in the nursery is built with multiple floors, with each floor 50cm apart, effectively saving space.

Next, people arrange sawdust bags on the trellis, making sure that the bags are about 7 – 10 cm apart. The incubation process lasts about 60 – 70 days, allowing the mycelium to grow deep into the sawdust material and create a uniform white color.

During this time, maintaining the ventilation of the nursery room is important, and removing moldy bags to prevent cross-spreading of the disease. At the same time, implement measures against rats, bugs and pests to protect sawdust bags and ensure the safety and quality of mushroom products.

How to care for and harvest mushrooms

After the fiber growing stage, when the sawdust bag has mushroom fibers growing evenly and discreetly, people open the cotton bag and its mouth and move them to another room, different from the nursery room. This room needs to maintain 80% humidity, with a temperature of about 16 – 18 degrees Celsius.

About 15 days later, the mushrooms will begin to grow, and farmers can begin the harvesting process. The mushroom growing season usually lasts about 4-5 months before ending.

Each bag of mushrooms grown by this method can yield about 600 – 800g of fresh mushrooms. If not sold immediately, people need to store them in plastic bags at cold temperatures to keep the mushrooms properly preserved for a reasonable period of time. This helps ensure the freshness and quality of mushroom products.
