红麻全秆堆贮致霉的重要条件是大气湿度和麻秆含水量。湖南沅江历年旬平均湿度很少超过９０％，将堆贮麻秆起始含水量控制在２５％以下，堆垛离地面０．５米以上，设置纵、横通风道，辅以覆盖防雨，堆贮２个月，麻秆含水量可降到１５％左右，堆贮一年，麻秆霉变损失可控制在５％以下。鉴于霉变菌种类庞杂，无处不有，用药剂处理麻秆防霉仅能收到短期效果，待药剂分解失效后，只要湿度适宜，空气中及附着在麻秆上的霉变菌又可很快繁殖致霉。
Kenaf whole stalk pile mold storage is an important condition of atmospheric humidity and stalk water content. Hunan Province rarely over 90 years of average humidity over the years, the heap stalks start water content controlled below 25%, stacking more than 0.5 meters above the ground, set vertical and horizontal ventilation, supplemented by rain, Storing for 2 months, the moisture content of hemp stem can be reduced to about 15%, heap for one year, mildew mold loss can be controlled below 5%. In view of the complex types of moldy, ubiquitous, with the treatment of mold stem mold can only receive short-term effects, until the failure of pharmaceutical decomposition, as long as the appropriate humidity, air and attached to the mold on the mulberry mold can Rapid breeding mold.
