目前,香菇野外栽培主要采取菌筒式,但存在耗材量大,污染率高,工艺复杂,及管理费工等问题。为了解决这些矛盾,各地正致力于香菇生料栽培的探索,归纳起来有以下几条途径:1.加大菌种量:采用不少于50～70％的菌种加入生料,以便短期内占据生料阵地,但往往仍是杂菌占优势而失败。2.降低培菌 At present, mushroom cultivation in the field mainly adopts the cartridge type, but there are problems such as large amount of supplies, high pollution rate, complicated process, and management costs. In order to solve these contradictions, various localities are devoting themselves to the exploration of raw material cultivation of mushrooms. There are several ways to be summed up as follows: 1. Increase the amount of bacteria: add 50% to 70% Occupy raw material positions, but often still dominate and failed. 2. reduce bacteria
