在毛主席革命路线指引下,在各级党委的正确领导下,几年来,我区广大贫下中农大力开展应用“鲁保一号”菌防治大豆菟丝子的群众性科学实验运动,防治面积达20余万亩,效果一般在80％左右。实践证明,“鲁保一号”菌是防治大豆菟丝子良好的生物制剂。“鲁保一号”菌和其他微生物一样,在室内经过多次传代培养由于各种因素的影响,常发生退化变异。主要表现孢子形态不整齐,菌体比原菌种缩小三分之一,菌落由
Under the guidance of Chairman Mao’s revolutionary line and under the correct leadership of the Party committees at all levels, over the past few years, the vast majority of poor and middle-level peasants in our region have energetically carried out mass scientific experiment campaigns using “Luba No.1” bacteria to control soybean dodder, with a control area of more than 20 Mu, the effect is generally about 80%. Practice has proved that “Lubaoyou” bacteria is a good biological control of soybean dodder. Like the other microorganisms, “Luobao No.1” strain often undergoes degenerative variation due to various factors in the house after multiple subcultures. Mainly irregular spore morphology, bacteria reduced by one-third of the original strain, colony from
