摘　　要：对不同温度和相对湿度条件储藏的稻谷进行微生物活动和品质监测，实验结果表明，稻谷在30℃、相对湿度70％～80％条件下储藏42d，微生物活动的水平相对较低，没有对储藏稻谷的品质造成明显的影响；当储藏环境相对湿度超过80％后，稻谷中的微生物活动明显增加，储藏21天的微生物活性检测值均可超过500u；特别是当环境相对湿度大于90％时，储藏稻谷的品质将受到显著的影响。高相对湿度环境主要影响储藏稻谷表层的微生物活动，粮层对湿度的扩散有显著的阻挡作用，相对湿度低于90％，30℃、21d内，不会对0．25m粮层以下稻谷微生物活动产生明显的影响。The detection of microbe activity and paddy quality for the paddy stored at different temperature and humidity were carried out. The results indicated that the microbe was inactivity and non - destroy for the quality of paddy 30℃ and 70 % - 80 % RH for 42 days. The microbe on the paddy flourished and the microbe activity value were over 500u after 21 days when the relative humidity exceed 80 o,6, and the paddy quality damaged when the relative humidity exceed 90 %. The grain bulk can block the humidity diffusing, and the microbe activity of paddy below 0.25m did not increased clearly below 90 % RH and 30℃ for 21 days.
