根据中国农科院油料所革委会科研生产组报导,花生追施“五四○六”菌肥有抑制花生根瘤菌生长,降低产量的趋势。试验进行四个处理:1)、“五四○六”开沟条施,2)、“五四○六”撒施培土,3)、饼土撒施培土,4)、空白对照。除空白对照外,均按饼土1:9,每亩用量200斤,施用时期为七月十七日,花生结荚期。于八月三日检查长势、叶色、封行情况,饼土处理与对照相似,追施“五四○六”的处理最差,叶色变黄,苗小,根瘤有的霉烂。收获前九月二十二日取样调查结果如表:
According to the research report of the Research Institute of Oil and Agriculture Revolutionary Committee of the Chinese Academy of Agricultural Sciences, peanut topdressing “May Fourth” bacterial fertilizer has the tendency of inhibiting the growth of peanut rhizobia and reducing the yield. The experiment carried out four treatments: 1) “trenching” under “May Fourth”; 2) “spreading soil under” May Fourth “; 3) applying earth and soil with cake and soil; and 4) blank control. In addition to the blank control, according to the cake 1: 9, 200 kg per acre, application period for July 17, peanut pod stage. On August 3, we checked the situation, the color of leaf and the situation of sealing the envelope. The processing of the cake was similar to that of the control. The treatment of ”May Fourth" was the worst, the leaf color turned yellow, the seedling was small, and the nodules were rotten. The results of sampling survey on September 22 before harvesting are shown in the table below:
