摘要

通过测定木霉T1010在土壤中的种群动态,评价T1010在土壤中的适应性和生命力,进一步挖掘T1010生态效应潜力。结果表明,随着樱桃番茄的生长,T1010孢子开始在土壤中萌发、生长,T1010种群数量均大幅度提高,与土壤中初始接种量相比,增长量高达31倍;通过来源不同的土样比较,T1010种群数量不同,来自日光温室周边的土壤利于T1010的繁殖,种群动态符合S生长曲线,菌落数量达到接种量的33倍;在樱桃番茄结果期,在离主根5~10 cm处土壤T1010种群数量大;5~20 cm耕作层土壤,T1010生长最好,T1010种群数为接种量的32倍。T1010处理组与常规对照相比,樱桃番茄始花着果期、结果期提前,果实整齐均匀,侧根数比常规化肥处理组增加144%,立枯病感病指数降低36.36%。木霉在不同土壤生态环境存活数量不同,为木霉制剂在不同环境中应用提供理论依据。
Improved colonization vigor of biocontrol agent during soil inoculation is crucial to their effective application.After mixing with the soil by the Trichoderma 1010 agent and its colonization,the population dynamics of T1010 in the soil of greenhouse was measured and analyzed.The pot experiment indicated that Soil 4 from the circumjacent areas of the solar greenhouse was beneficial to the propagation of T1010,and its population dynamics complied with S growth curve,and the amount of the colony was 33 times as large as the inoculation amount.It can be seen in the pot experiment that the colony amount of T1010 reached the maximum in the soil at a distance of 5 —10cm to the axial root.Similarly,T1010 grew best in the soil at a depth of 5 — 20 cm,and the amount of the colony in the pot experiment was 32 times as large as the inoculation amount.Compared with the control with regular management,the numbers of lateral roots of the colonized cherry tomato increased 144%.The index of infection decreased by 36.36%by preventive effect of T1010 on the Rhizoctonia solani Kuhn disease compared to the control.The vigor and amount of Trichoderma are different in ecological environment with different soil,root distances or soil depths.
