Straw mushrooms take only 7-10 days from spawning to cultivation: cultivation techniques
I. Determining the cultivation period. Straw mushrooms (Volvariella volvacea) like high temperature and high humidity, so in northern regions they should be grown in summer. In central Hebei and southern Hebei, this is generally from late May to early September, when the temperature inside plastic greenhouses can be maintained at 22-31°C. When cultivated in this period, the mycelium generally germinates on the second day after spawning, the mycelium runs through the substrate on the third day, and the first flush of mushrooms can be harvested on days 7-9; growers in other regions can adjust the cultivation period flexibly according to local climatic conditions. II. Selection and treatment of the growing substrate. The growing substrate is the nutritional medium for growth, and choosing a suitable substrate is

Button Mushroom Spawning Methods and Technical Key Points
(1) Spawning date. In each region, an appropriate spawning period must be chosen according to local climatic conditions. The standard for the optimal spawning period is: during the mycelium-running stage of the compost, the natural temperature should be 24-26°C as far as possible. In the Yangtze River basin area, the spawning period is in early to mid-September; in Shanghai and areas near Shanghai, the optimal spawning period is September 8-12. If spawning is too early, temperatures above 28°C are often encountered after spawning, causing the spawn not to germinate and to die; if spawning is too late, the number of days suitable for fruiting is shortened, making it difficult to obtain high yields. (2) Before spawning

Indoor Cultivation Techniques for Oyster Mushrooms: Detailed Explanation of Compounding, Filling, and Spawning Methods
1. For the formula of the growing substrate, cottonseed hulls are generally the better choice, because cottonseed hulls are relatively rich in nutrients and also have good air permeability. Choose dry cottonseed hulls with no mold, and it is best to sun-dry them for 2-3 days in advance. The raw material formula is: 100 kg cottonseed hulls, add 2 kg superphosphate, 3 kg gypsum, 0.2 kg carbendazim, and add about 150-160 kg water (depending on how dry the cottonseed hulls are and how much cotton lint they contain). Mix the above raw materials thoroughly, and adjust the moisture until it feels right when squeezed tightly by hand: water droplets appear between the fingers but do not drip
