Greenhouse vertical (standing stick) cultivation is a mainstream and high-efficiency planting method for shiitake mushrooms. Growers remove the outer bags of mushroom logs in the greenhouse and lean the logs on fixed wire frames. The planting density is 12,000 bags per acre.
Fruiting Period
1. Seasonal production: August-November & April-June of the next year
2. Off-season production: May-October (heating facilities are required during the mycelium growth stage)
Core Advantages
This cultivation mode delivers high yield and superior mushroom quality. It features water saving, effective bag rot prevention and safe product quality. It supports water-free fruiting, staggered fruiting periods, and efficiently solves the problem of labor shortage in mushroom planting.
1. Construction of Mushroom Growing Racks
On level ground, install steel reinforcement frames at a spacing of 2 meters. Each frame is 25cm in height and 1.4m in length. Fix steel wires or anti-aging ropes on the frames with a row spacing of 22-25cm. Reserve a 50cm-wide walking path in the middle of the greenhouse.
The standard layout is 6 rows in the middle area and 3 rows on the edge areas. The layout can be flexibly adjusted according to actual site conditions for convenient daily management.
2. Bag Removal & Mushroom Log Placement
2.1 Bag Removal Timing
When irregular small blisters and brown spots appear around the inoculation holes, move the mushroom logs into the greenhouse for 7-10 days of hardening treatment. Complete bag removal on sunny or cloudy mornings.
2.2 Two-Time Bag Removal Method (Recommended)
First cut open the film of mushroom logs as required, then lean the logs against the growing racks. This operation increases oxygen supply, promotes natural color transformation inside the logs, and accelerates mushroom bud formation before full bag removal.
Applicable scenarios: Ambient temperature above 25℃ or below 12℃; novice growers with insufficient bag removal experience.
3. Key Notes for Bag Removal
Morning is the optimal time for bag removal (low temperature and high humidity). Afternoon operation is not recommended, as high temperature and dry wind will dehydrate log surface mycelium, hinder color transformation and affect fruiting.
3.1 Weather Requirements
Only operate on sunny or cloudy mornings. Avoid operation on hot sunny days (easy water loss), rainy days (high miscellaneous fungus infection risk) and windy days above Level 3 (log surface dehydration).
3.2 Temperature Requirements
The optimal temperature for bag removal is 18-22℃.
- Temperature above 25℃: Only mycelium grows, no primordia formation, causing overgrowth of mycelium
- Temperature below 12℃: Slow mycelium recovery, difficult log color transformation
3.3 Timely Film Covering
After bag removal and log arrangement, cover the logs with film immediately to prevent surface dehydration and ensure smooth color transformation.
3.4 Broken Log Repair
Handle mushroom logs gently during bag removal to avoid breakage. Reconnect broken logs with bamboo skewers in time.
