摘要选择高锰酸钾、石灰或草木灰、腐熟农家肥等有机投入品对根肿病的控制效果和施用方法进行了初步尝试。

Result The results revealed that different concentration of C6-HSL could obviously inhibit the growth rate of root and the number of roots, but have no effects on plant height, number of nodes and leaf size. The POD and SOD activities and the concentration of H2O2 showed a significantly increased when the potato implants were pretreated with C6-HSL, however, no effect of C6-HSL pretreatment on PAL and PPO activities were found. The ability of resistance aginst Erwinia carotovora subp. carotovora was signifinantly improved after treated by C6-HSL. Incidence was obviously lower than the control group.

结果］不同浓度的C6-HSL能明显抑制马铃薯的出根率和生根数，而对株高、茎节数及叶片大小没有影响；植物标志性防御酶类中POD和SOD的活性以及H2O2的产生量经C6-HSL诱导后显著提高，而PAL和PPO的活性则没有明显变化；抗病试验中，经C6-HSL诱导的马铃薯植株能有效抑制胡萝卜软腐欧文氏菌的侵染，发病率明显低于对照组。

In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.

本研究从长期连作田种植的大豆及其根际土壤中分离细菌1554株，采用平板测试、温室盆栽及田间试验等方法，筛选了对大豆根腐病菌(主要是尖孢镰孢菌Fusarium oxysporum)有很好作用效果的生防细菌6株，在离体的条件下均表现出不同程度的拮抗作用，其中生防细菌18BR2-2和18BR9-1表现出很广的杀菌谱，对大豆根腐病菌尖孢镰孢菌(F.oxysporum)、燕麦镰孢菌(F.avenaoeum)、茄腐镰孢菌和立枯丝核菌都有很好的离体拮抗作用，并且这6株生防细菌在盆栽和田间的情况下均表现出对大豆根腐病一定的防治效果。

Shake hands and hold pots, make humus tight, and then narcissus bulb plate located in the basin, and then continue to the soil about 1 cm, then Jiaotou water, and then pot in the shade , 5 days until bulb set to grow roots, it will flower pot into a sunny office culture ...

双手抱盆摇动，使腐殖土紧实，然后将水仙鳞茎盘座落在盆中，再继续加土约1厘米左右，接着浇透水，然后将花盆放在阴凉处，5天后待鳞茎盘长出根后，将花盆放到有阳光处养殖。。。。

Most are saprobes living in soil,dung,or rotting wood.A few species are involved in mycorrhizae.

盘菌大多数为腐生菌，生活在土壤、粪便或朽木上，少数种类与菌根的形成有关。
