Detailed Explanation of Chestnut Mushroom Cultivation Techniques and Planting Management Methods

To cultivate chestnut mushroom, choose a plot with high terrain, facing the sun, and convenient drainage and irrigation, and do a good job in sterilization and disinfection, making beds, and watering. After that, plant the mushroom sticks properly, build a shade shed, and cover with plastic film and straw curtains. Then before fruiting, spray water appropriately every day or every few days. 7-10 days before budding, further increase the amount of water sprayed, and finally ventilate and raise the temperature appropriately. The detailed cultivation techniques are as follows:

1. Site selection and land preparation

For open-field cultivation, choose a plot with high terrain, facing the sun, and convenient drainage and irrigation, preferably sandy soil, and it is even better if there are coarse sand particles. Then in the selected site, dig small beds running east-west, 2.5-3.0 m long, 45 or 55 cm wide, and 25-30 cm deep, with a row spacing of 80-100 cm between beds. After the beds are made, expose them to the sun for 2-3 days. One day before cultivation, irrigate the beds once with a large amount of water. The amount of irrigation depends on the soil moisture. After the water seeps in, sprinkle a little lime in the beds.

2. Cultivation

Before planting the mushroom sticks, disinfect the planting tools, the outer packaging bags of the mushroom sticks, and the hands of the workers with 4% Lysol. Then arrange the mushroom sticks in the beds. After the mushroom sticks are planted, fill the gaps between the sticks tightly with new soil, and cover the surface of the sticks with a 1 cm thick layer of soil.

3. Growth management

Depending on the cultivation season and fruiting time, the management methods for the four major factors of temperature, humidity, light, and air also differ, and can be roughly divided into 3 stages. From after the mushroom blocks are covered with soil until the primordia emerge, depending on the water retention performance of the soil, spray water appropriately every day or every few days to keep the surface from drying out; for cultivation after removing the bags before the end of April, fruiting generally does not occur until mid-to-late May, and the first flush mushrooms are large and of good quality. For cultivation after removing the bags in June-July, fruiting generally occurs in 15-20 days, but the yield of the first flush is relatively low. In some cases, fruiting can occur on the seventh day, formed by the direct growth of primordia inside the bag, and the mushroom shape is relatively small. Generally, fruiting can occur after 25-85 days; after the primordia form, increase the humidity in the beds, strengthen ventilation, enhance light, and appropriately regulate the temperature.

In addition, during the cultivation period of chestnut mushroom, be sure to pay attention to temperature and humidity, ventilation and air permeability, light, and pest and disease control.
