摘要
在播种前和定植后分别向基质中添加FZB-42、GM以及Bio微生物菌剂,研究其对黄瓜生长和基质环境的影响。连续3茬试验结果表明:添加GM菌剂减缓了基质pH值的升高速度,提高了基质的电导率,改善了基质营养供应能力;FZB-42处理能显著减少基质中细菌数量,增加放线菌数量;FZB-42、GM和Bio处理的黄瓜根长分别比对照增加57.1%、51.8%和44.9%,根表面积增加了56.5%、51.5%和44.3%,根体积增加了35.4%、82.3%和61.1%;不同菌剂处理均能提高黄瓜单株产量,Bio和GM处理增产效果明显。
Substrates were treated with various amounts of Bacillus amyloliquefaciens,Glomus Mosseae and a commercial bio-fertilizer called Bio twice prior to sowing and after transplanting,in order to figure out the effects of those micro-fertilizers on cucumber(Cacumis sativus L.)root zone environment and yield.The results of 3 constant seasons' experiments showed that Glomus Mosseae can slow down pH value from raising too fast and can increase EC value in adequate range.Bacillus amyloliquefaciens can significantly decrease the numbers of bacteria,while increase actinomycetes numbers.Bacillus amyloliquefaciens,Glomus Mosseae and Bio can increase root length by 57.1%,51.8% and 44.9%,respectively.They can enlarge root surface areas by 56.5%,51.5% and 44.3%;in addition,all these 3 treatments can increase root volume by 35.4%,82.3% and 61.1%,comparatively.Different micro-fertilizer treatments can improve cucumber plant yield,Bio and GM treatments have remarkable effect on yield increase.
