Introduction

Analysis of the core content of the standard

Technical dimensions	Three-dimensional cultivation	Ground cultivation
Facility requirements	Steel frame structure load-bearing 150-200kg/㎡, hanging rod spacing 0.3m	Bed height 0.1-0.15m, working road width 0.5-0.6m
Water management	Alternating dry and wet cycle (spraying water → drying bags 2-3d → cycle)	Same as three-dimensional cultivation mode
Space utilization	6-8 sticks per string, bottom layer ≥0.3m from the ground	25-30 sticks (short sticks) or 20-25 sticks (long sticks) per ㎡

Key Technical Points

1. Standardized process for mushroom stick production

The moisture content of the substrate is strictly controlled at 55%-60%, and the pH value is 7.0-8.0. Sterilization steps:

Normal pressure sterilization: short rod 8-10h, long rod ≥30h (100℃)
High pressure sterilization: 120-125℃ for 2-3h

2. Differentiated solutions for ear management

Three-dimensional cultivation case

A base in Heilongjiang uses a rope suspension system, combined with an automatic spray device, to achieve precise control of humidity at 75-85%, increasing the yield of a single rod by 23%.

Implementation suggestions

Environmental monitoring: Install temperature and humidity sensors to collect culture room data in real time
Selection of strains: Select stress-resistant varieties approved by the provincial government (such as "Heiwei No. 15")
Recycling: Mushroom residue is returned to the field as organic fertilizer after high-temperature composting

Analysis of standard evolution

Compared with the 2013 version of NY/T 2375, this standard adds:

The sterilization time of long rods is extended from 24h to 30h
The number of puncture holes is accurate to the rod (160-240 holes for short rods and 190-220 holes for long rods)
Clearly list of banned pesticides (refer to NY/T 393)
