寒地越冬模式下的羊肚菌生产菌株筛选

Screening Study of the Morchella esculenta Production Strains in the Overwintering Model in Cold Regions

  • 摘要: 以引进的22株羊肚菌生产菌株为试材,对比不同菌株cPDA平板培养基和栽培种培养基菌丝生长情况,寒地条件下暖棚内采用“秋播春收”模式,研究了cPDA培养基和栽培种培养基生长情况,并进行栽培比较试验,以期选育出适于寒冷地区栽培的优良生产菌株。结果表明:22个生产菌株,依据cPDA平板培养基生长情况可分为3个组群;依据栽培种生长情况可分为2个组群;从栽培试验结果看,9号菌株出菇早,产量最高,单畦产量为5 319 g; 21、19号和12号菌株相较于9号菌株出菇晚,单畦产量分别为4 341、4 059 g和3 429 g,经3个生产周期多点试验栽培,均取良好效果,初步确认这4个菌株可在寒冷地区推广使用。

     

    Abstract: Twenty-two production strains were used as materials to compare the mycelium growth in cPDA medium and cultivated medium.The growth of cPDA medium and cultivated medium was studied under the cold conditions and the ‘autumn sowing and spring harvest’ model.Cultivation tests were also used to compare different strains, in order to screen suitable production strains of Morchella esculenta for cultivation in cold areas.The results showed that 22 strains were divided into 3 groups, according to the growth in cPDA medium; while they were divided into 2 groups, according to the growth of cultivated tests.Base on the cultivation test results, the fruiting bodies of strain No.9 formed earlier, and strain No.9 had the highest yield, with a single border yield of 5 319 g.The fruiting bodies formation time of strain No.21,No.19 and No.12 performed later than strain No.9,the yield was 4 341 g, 4 059 g and 3 429 g, respectively.Good results were obtained after three production cycles of multi-point test cultivation.It was preliminarily confirmed that four strains could be popularized and used in cold areas.
