摘　　要：为评估田间连续移栽由根际促生菌与普通育苗基质联合研制成的生物育苗基质所育种苗的增产效果,通过田间试验,研究连续5季,移栽含解淀粉芽胞杆菌SQR9生物育苗基质所育种苗对设施黄瓜产量、生物量、土壤理化及尖孢镰刀菌数量的影响.结果显示,连续5季移栽生物育苗基质所育黄瓜种苗处理（OFNS）的黄瓜产量,每一季均高于移栽普通育苗基质所育黄瓜种苗对照（OF）的产量,在第1、2、3、4和5季,分别提高了2.74%、4.35%、5.95%、15.14%和11.07%,且第4和5季产量间具有显著性差异.相比于OF处理,OFNS处理连续5季均提高了黄瓜的株高和茎粗,有效提高了土壤中速效钾、速效磷、电导率、全氮和总钾的含量,同时降低了土体土壤和根际土壤中尖孢镰刀菌的数量.本研究表明,连续5季移栽生物育苗基质所育种苗能够有效促进黄瓜生长和提高黄瓜产量,结果可为根际有益微生物新产品的开发提供新思路以及为设施蔬菜高产栽培提供指导.Bio-nursery substrate is produced by combining plant growth-promoting rhizobacteria （PGPR） with ordinary nursery substrate. The transformation of seedlings with the novel product （bio-nursery substrate） in the field can then be used to evaluate the yield-enhancing effects of the substrate, which can provide practical guidance and support for the development of high-yield plantations in facility agriculture, as well as for the effective application of PGPR. In the present study, the effects of transforming cucumber seedlings using a bio-nursery substrate produced by combining Bacillus amyloliquefaciens SQR9 and ordinary nursery substrate on the plant biomass, fruit yield, soil physiochemical properties, and Fusarium oxysporum f. sp. cucumerinum numbers were investigated in five successive seasons of field experiments in a plastic greenhouse. Results showed that over five continuous seasons the transformation of cucumber seedlings with a bio-nursery substrate （with organic fertilizor and nursery strain, OFNS） resulted in a higher fruit yield compared to that of control seedlings transformed with the ordinary nursery substrate, and yields were increased by 2.74%, 4.35%, 5.95%, 15.14%, and 11.07% in the 1st, 2nd, 3rd, 4th, and 5th seasons, respectively. Significant differences were also observed between the 4th and 5th seasons. Moreover, during these 5-season-long experiments, OFNS treatment improved the plant height and stem diameter, enhanced the content of available potassium, available phosphorus, electrical conductivity （EC）, total nitrogen （TN）, and total phosphorus （TP） in the soil, and reduced the number of F. oxysporum in both the bulk and rhizosphere soils compared to the control. In summary, the results of the field experiment conducted over 5 consecutive seasons indicated that the transformation of seedlings in a bio-nurserysubstrate effectively promoted plant growth and enhanced fruit yields. These results will help provide a novel strategy for developing new PGPR products and sup
