经过对四川省内有代表性的地区(宜宾、乐山、温江、绵阳)82年新入库油菜籽微生物区系分布的调查,分离出油菜籽内外部的微生物共19属30多个种。外部平均带菌量为:细菌183—12561千个/克,以草生假单孢杆菌为优势菌,真菌2.7—148千个/克,以细交链孢霉为优势菌;油菜籽内部真菌平均感染率2.3—22.3%以细交链孢霉为优势菌。上述四地区比较,宜宾地区油菜籽内外部带菌量最高,菌相也比较复杂。这主要与当地的地理、气候条件、收获方式及油菜籽的品种品质等因素有关。
After investigation of the distribution of micro-flora of rapeseed newly introduced in 1982 in representative areas in Sichuan Province (Yibin, Leshan, Wenjiang and Mianyang), a total of 19 genera and 30 species of rapeseed were isolated. The average external bacteriostasis amount was: 183-12561 bacteria / gram, Pseudomonas aeruginosa was the predominant bacteria, fungi 2.7-148 thousand / gram, the dominant bacteria were Alternaria alternata; the average infection rate of the inner fungi in rapeseed The rate of 2.3-22.3% to the Penicillium sp. For the dominant bacteria. The above four areas, Yibin rapeseed inside and outside the highest amount of bacteria, bacteria phase is more complicated. This is mainly related to the local geography, climatic conditions, harvesting patterns and the quality and variety of rapeseed.
