When actinomycetes antagonist is cultured in the cotton seed cake and usedas a fertilizer for cotton,a stimulating effect on growth of the plant and a decr-ease of percentage of Verticillium wilt has been observed.The isolates of Actino-mycetes which have shown the best results are G_4 and 5406.Throughout thegrowing period,three applications of the antagonist carried fertilizer show a decr-ease of 31-50% disease and an increase of 14-40% yield.The three applicationsof the antagonist carried fertilizer seem to be better than that of two applications.However,the yield increase due to the fourth application can hardly cover the costof labour and material. According to the results of a burried-slide test for inspecting the dynamics ofthe antagonist in certain depths of soil,it is found that the actinomycetous isolatesG_4 and 5406 survive a comparativly longer period at a soil depth of 2.5-10 cm.,buttheir amount per unit volume of soil is gradually reduced with time.The anta-gonists are most abundantly distributed at a depth of 5-7.5 cm.It is suggestedthat three applications of the antagonist carried fertilizer may be practical in con-trolling the Verticillium wilt of cotton.

1.1954—1956年在辽陽和北京两地的田間試驗証明:施用“加用抗生菌的肥料”后,不仅能增加棉花的出苗、刺激棉株的生育,并且对黃萎病有显著的防治作用,增产的效果很明显。2.从不同菌种的效能来看,都有防病增产的作用。其中的G_4和5406号抗生菌(均屬放綫菌)的效果最好。进行三次分施时,可减輕發病率31—50%,增加产量14—40%。402号抗生菌种有引起花蕾脫落的恶果;3号及13号虽有显著的防病作用,但增产效能不如G_4。3.不同的抗生菌种混合施用时,沒有表現出增强的作用。4.抗生菌肥料施用的次数,以愈多愈好。在播种前十天作为基肥一次施入者,防病的作用最差,增产作用也不显著。两次分施的,必須在播种时沟施小部份,而将大部份在显蕾期中施入;三次分施的,一般較二次分施的效果高。基肥时不施,单在定苗、显蕾、开花期分施的,对黃萎病的防除效果較大,而对增产作用較小。分四次施肥,所須人工太多,防病、增产的效果并不比三次分施的显著提高。5.根据“埋片法”檢查施入的抗生菌在棉田中消长情况的結果,証明C_4号及5406号放綫菌施入棉田后,在2.5—10厘米深处能維持很长的时間,但其菌量随时間延长而逐漸减少。单施棉籽餅的,在2....

At the same time, the antagonistic effects of the 12 strains against collectotrichumgossypii,Fusarinm oxysporam were measured.The pot exporiment showed that the cotton seedlingmoralities of 5 treatments(spraying 5 different strains)droppod 6.78%~15. 75%as compared withthe CK,The 5 strains were identified as different groups of streptomyces, The further research wasdiscussed in the end.

采用稀释平板法从全省各地不同类型的土壤中共分离到放线菌4885株。以棉花立枯病菌(Rhizoctoniasolani)为指示菌,测定固体培养基平板生长的放线菌的抑菌作用,获拮抗菌株624支,占12.77%,其中53支菌株表现出较强的抑菌作用。上述624支菌株发酵液拮抗作用的测定表明,有45支菌株对R.solani有抑制作用,占7.21%,其中有12支菌株表现出较的抑制作用。同时测定了这12支菌株对棉花炭疽病菌(Collectotrichumgossypii)、棉花枯萎病菌(Fusariumoxysporum)的抑制作用。盆栽试验表明有5个处理(喷5个菌株的发酵液)的棉苗死亡率比对照降低6.78~15.75%,经鉴定,这5支菌株均匀为链霉菌属(Streptomgces)的不同类群。文未对今后的研究进行了阐述。
