地上部和根系禾谷丝核菌菌量为组织鲜重,土壤为干重;小麦生育时期THS、TIS、OS、RES、RIS、JS和HS分别代表三叶、分蘖、越冬、返青、起身、拔节和抽穗期;玉米生育时期TLS、JS、TRS、TAS和MS分别代表三叶、拔节、大喇叭口、抽雄和乳熟期
Fig. 3. Distribution characteristics of R. cerealis in wheat (A) and maize (B) double cropping system
Content of R. cerealis was in fresh weight for the aboveground and root tissue, and was dry weight for soil, respectively. THS, TIS, OS, RES, RIS, JS and HS in growth stage of wheat stand for three-leaf stage, tillering stage, overwintering stage, regreening stage, rising stage, jointing stage and heading stage, respectively. TLS, JS, TRS, TAS and MS in growth stage of maize stand for three-leaf stage, jointing stage, trumpet stage, tasseling stage and milking stage, respectively
