嫁接对寒地棚室茄子根际土壤微生物的影响

以"托鲁巴姆"茄子为砧木,以"龙园棚茄一号"为接穗,研究了嫁接技术对连作棚室茄子根际土壤微生物的影响。结果表明:随着连作年限的增加,未嫁接茄子根际土壤中的细菌和放线菌的数量明显降低,而真菌数量则明显增加,采用"托鲁巴姆"为砧木嫁接后与未嫁接相比,土壤中的细菌和放线菌稍有降低,但基本上仍维持在较高水平,真菌略有增加,土壤中的微生物数量基本上维持在相对平衡的水平。

Effect of Grafting on Soil Rhizosphere Microorganisms of Solanum melongena L.in the Plastic Greenhouses in Cold Area

The Solanum melongena L.of tuolubamu were used as the rootstock and the 'Longyuan No.1'as the scion in study on the effect of grafting technology on soil rhizosphere microorganisms of Solanum melongena L.in the plastic greenhouses in cold area.The results showed that the increasing of the continuous cropping year,the amount of bacteria and actinobacteria of soil rhizosphere of non-grafting decreased obviously,the amount of fungi increased obviously. Compared with non-grafting,the grafting used Tuolubamu as ...
