摘要
以自然重壤土和无菌砂为培养基质,栽种大豆,采用MPN法测数,证明了大豆根瘤菌数量的增长符合逻辑斯谛模型并编写了相应的BASIC程序。通过6组试验数据的计算,发现根瘤菌接种量和其占瘤率之间存在一定的数学关系,并编写了相应的BASIC程序。
In this paper, leguminous plants grown in both natural heavy loam and sterile sand were studied. The increase of Rhizobium japonicum number conforms to Logistic model using MPN method, and a corresponding BASIC program about counting is compiled. There is a mathematical relationship between inoculum rate and nodule occupancy by counting six groups of data, and also, a corresponding BASIC program about counting is compiled.
