通过7个水稻品种的灭菌土与不灭菌水稻土的盆栽试验和4个品种的田间调查试验结果表明：水稻不同的栽培条件、不同的品种、不同的生长发育期，水稻根际土壤真菌的数量、种群动态及根际效应是有差异的。未灭菌土壤的盆栽试验，根际土壤每克干土的真菌数量范围是273～24359个，各品种平均真菌数最高为6429个；灭菌土盆栽的数量范围是每克干土154～15118个，各品种平均真菌数最高为4488个；田间试验，最高达34369个，各品种平均真菌数最高为9128个。水稻根际土壤真菌的根际效益都很显著。最高可达191．9倍。田间水稻根际土壤真菌较盆栽的丰富，未灭菌盆栽上的根际真菌穗期以前一般较灭菌盆栽土丰富。
The pot experiment and the field investigation of 4 cultivars of sterilized soil and non-sterile paddy soil of 7 rice cultivars showed that different rice cultivation conditions, different varieties, different growth and development stages, rhizosphere soil fungi The number of population dynamics and rhizosphere effects are different. In the pot experiment of non-sterilized soil, the number of fungi per gram of dry soil in rhizosphere soil ranged from 273 to 24359, and the average number of fungi in each species was up to 6429. The number of sterile soil pots ranged from 154 to 15118 The average number of fungi in each cultivar was 4488, the highest was 34369 in field experiment, and the average number of fungi in each cultivar was 9128. Rhizosphere soil fungi rhizosphere benefits are significant. Up to 191.9 times. The rhizospheric soil fungi in field rice were more abundant than potted plants, and the rhizospheric fungi on non-sterile pots were generally more abundant than the sterile soil for potting.
