摘要
以云南永胜县涛源乡选择水稻超高产生态区土壤为对象,对水稻根际微生物主要类群量数量进行了探讨。结果表明,在水稻生长过程中,不同产量田块水稻根际的细菌和放线菌数量为组合II优28>甬优6号>汕优63>II优725(cK),水稻的产量情况与其变化一致,真菌数量为组合甬优6号>II优28>汕优63>II优725(cK)。水稻根际细菌、真菌和放线菌数量随着生育期的变化是不一致的。而在同一生育期,不同的水稻产量田块根际细菌、真菌和放线菌之间存在显著不同的差异。根际微生物数量大的其不同水稻田块的产量也高。
Original study on physiological populations and quantity of rhizosphere microorganism was worked on which selected the soil of super-high ecological rice fields in Taoyuan county Yunnan province.During the growing periods of rice,it was showed that the count of bacteria and actinomycetes were foundⅡyou28〉Yongyou6〉Shanyou63〉Ⅱyou725(cK),so did the changes of rice yields.The count of fungi Yongyou6〉Ⅱyou28〉Shanyou63〉Ⅱyou725(cK).The quantity fluctuating of the rhizospheric bacteria,fungi,actinomycetes were not in accordance with the rice growing stage.It was different distinct differences that The quantity changes of the rhizospheric bacteria,fungi,actinomycetes in the same growing periods in different fields.In addition,the more abundant microorganisms quantities,the higher rice yields.
