Twenty two strains(14 bacteria and 8 actinomyces strains) of antagonistic microorganisms against Fulvia fulva were isolated from vegetable field soil.

从蔬菜地田间土壤中筛选出对番茄叶霉病具拮抗作用的22株菌株，其中14株细菌，8株放线菌。孢子萌发抑制试验表明，细菌X14菌株和放线菌F15菌株的发酵液及其离心后上清液对番茄叶霉病菌孢子萌发抑制率均达100%。

Especially, the inhibition zones out to the width of 14.8-15.0 mm were presented by the strain against 2 ones of the pathogens, Fusarium oxysporum and Fulvia fulva The biocontrol effect of strain F-15 to leaf mold of tomato reached 73.2% in greenhouse.

温室防病实验结果表明：其发酵上清液对番茄叶霉病具有良好的生防作用，防治效果可以达到73.2%。

By comparing with the curves of classical antibiotics in Doskochilova system, the antibiotic type of fermentation broths was identified. The antimicrobial tests showed, the inhibition rate of alt the twenty strains were considerably and ten of them reached 80% when the fermentation broths was diluted by 10 times. It showed strongest inhibition effect against Erwinia carotorora (17.75 mm). Organize method tests showed that inhibition rate of fermentation broths of the strain HJ1-2 to Sclerotinia sclerotiorum and Botrytis cinerea was 100% and 71.39%, respectively.

发酵液的抑菌活性测定结果表明，放线菌HJ1-2菌株发酵液对20种供试病原真菌均具有不同程度抑制作用，其10倍稀释液对其中10种病原真菌菌丝生长的抑制率达到80%以上；供试7种细菌中放线菌HJ1-2菌株发酵液对白菜软腐病菌的抑制作用最强，抑菌圈直径为17.75mn；放线菌HJ1-2菌株发酵液对油菜菌核病和番茄灰霉病的抑制率分别为100和71.39%。

Result The phytopathogenic fungus Pythium aphanidermatum was isolated; 7 strains of antagonistic actinomycete, which had obvious inhibitory effects on Pythium aphanidermatum were screened. The inhibitory ring of No.8 strain was 13.3 mm, and reached 88.3% when cultivated for 120 h.

伽师甜瓜猝倒病的病原菌为瓜果腐霉；筛选出7株对瓜果腐霉具有显著拮抗性的生防放线菌，其中8号放线菌对瓜果腐霉的拮抗环宽度为13.3mm，其无菌发酵滤液对瓜果腐霉的抑菌率在培养120h时高达88.3%。

The inhibitory effect of different component from the filtrate of two antagonists was tested: the polysaccharose, crude fat, and protein produced by Gvirens had inhibitory activity to the spore germination of P.funerea, and the crude fat and protein was more significant, the protein more stable. The crude fat from B.firmus could completely inhibit the Rfunerea's spore germination, the inhibitory effect of polysaccharose and protein also was stable, but polysaccharose more excellent.

G.virens与B.firmus的亲合性研究显示，G.virens发酵滤液在70％浓度以下对B.firmus的生长繁殖无明显抑制作用，在70％以上浓度，B.firmus的生物量有所下降；而B.firmus发酵滤液对G.virens的生长繁殖无明显抑制作用，这种状况有利于二者在植物病害生物防治中协同作用的发挥，表明了两种微生物在松赤枯病生物防治中联合作用的可能性。

Their fermentation filtrates had significant inhibitory effects upon the pathogen, with the inhibitory rates as 73.72% and 75.32%, respectively.

sp。 Mali具有较强拮抗作用的菌株，其中菌株B86和B91的发酵滤液在活体上时苹果斑点落叶病的防治效果显著，分别为73.72%和75.32%。

Then, mixed the fermentation liquid of the 8 antinomyces strains and spore the pathogens of Banana Fusarium wilt disease for 12 hours,the result shows those 4 strains\' antagonism all beyond 80%.

另在分别对这8株放线菌发酵上清液和香蕉枯萎病病原菌菌株孢子混合12h后，测其对病原菌的抑菌作用均超过80%。

Two outstanding fusants SR-7 and SR-T19 were chose out in the fusion group 90-11×FR-008, the former produces not only antibiotics the parents produced but also a new antibiotic effective gainst a wide range of both gram positive and negative bacteria, which the parents could not produce, and its product of the 37℃ fermentation was very effective against the cotton seedling damping off caused by Rhizoctonia sonali while product of the 26℃ was effective agaist the bacterial rots of turnip and Chinese cabbage; the latter have a much stronger activity against a wide range of fungi and yeasts than the parents.

在90-11×FR-008融合组合中，筛选获得2个优良融合子SR-7和SR-T19，前者除产生亲本产生的抗生素外，还产生亲本不产生的一种新的具有广谱抗细菌活性的碱性水溶性抗生素，防病试验表明，其37℃发酵产物对棉花苗期立枯病具有良好的防治效果，28℃发酵产物对萝卜和大白菜具有明显的防腐作用；后者与亲本FR-008的抗菌谱完全一致，但其活性强度都超过了FR-008；采用RAPD分子标记技术检测了SR-7和SR-T19与亲本的同源性及彼此间的差异，从而首次直接从DNA分子水平上验证了链霉菌的原生质体融合子及其遗传重组的多样性。
