摘　　要：有效活菌数是衡量颗粒微生物菌剂质量的重要指标。通过实验研究颗粒微生物菌剂水分、储存温度、光照对有效活菌数的影响。结果表明:随着颗粒微生物菌剂水分升高,有效活菌衰减加快,菌剂w(H_(2)O)为5.0%、15.0%、25.0%时,存放60 d后有效活菌分别衰减3.6%、9.1%、21.8%;随着储存温度升高,有效活菌衰减加快,在5、20、35℃存放60 d后,有效活菌分别衰减3.6%、5.5%、12.7%;当菌剂在室外储存,阳光直射条件下9 d有效活菌衰减41.8%,而避光存放则基本不衰减。为了减缓有效活菌衰减,提高颗粒微生物菌剂产品效果,用户应挑选水分较低的产品,同时尽量低温储存,避免阳光暴晒。The effective viable bacterial count is an important indicator for measuring the quality of granular microbial inoculants.Through experiments,the effects of moisture content,storage temperature,and light on the effective viable bacterial count of granular microbial inoculants are studied.The results show that the effective viable bacterial count decreases faster with the increase of the moisture content of the granular microbial inoculants,with the moisture content of 5.0%,15.0%and 25.0%,the effective viable bacterial count are reduced by 3.6%,9.1%and 21.8%respectively after 60 days of storage;The effective viable bacterial decays faster as the storage temperature of the particles increases,when stored at 5,20,35℃C for 60 days,the decay rates are 3.6%,5.5%and 12.7%respectively;When stored outdoors in direct sunlight,the effective viable bacterial decays by 41.8%within 9 days,while when stored away from light,it remains almost unchanged.In order to slow down the decay of effective viable bacteria and improve the effectiveness of granular microbial inoculants,users should choose products with low moisture content,store them as low as possible and avoid direct sunlight.
