摘  要：
对渭北旱塬50年生葡萄园解磷细菌进行了筛选,并对两个菌株的促生效应进行了研究。通过NBRIP平板,从葡萄根际土壤中分离得到29株解磷细菌。通过NBRIP液体摇瓶试验,培养7 d后得到两株解磷效果突出的菌株:JYR-12菌株培养液中有效磷含量高达673.99 mg/L,约有13.17%的磷酸钙被溶解出来;JYR-7菌株培养液中有效磷浓度为671.64 mg/L。在盆栽条件下,研究解磷细菌JYR-12和JYR-7对酿酒葡萄赤霞珠扦插苗生长及光合能力的影响。盆栽试验表明,接种解磷细菌处理的赤霞珠扦插苗株高、茎粗、地下干质量和地上干质量显著高于对照。葡萄扦插苗的光合指标及接种解磷细菌的均显著高于对照。可见,与对照相比,接种解磷细菌可以显著促进赤霞珠扦插苗生长,其中以菌株JYR-12效果最为明显。

摘  要：
Phosphate-solubilizing bacteria were screened and promotion effects on grapevine were studied.By using NBRIP plate method,29 strains of phosphate-solubilizing bacteria(PSB) were isolated from the grapevine rhizosphere.After seven days incubation in a liquid medium NBRIP,the soluble P in the cultures of strains JYR-12 and JYR-7 reached 673.99 mg/L and 671.64 mg/L respectively.About 13.17% of tricalcium phosphate was dissolved.In pot experiment,the growth of Cabernet sauvignon after inoculation with phosphate-solubilizing bacteria was studied.The results showed that the plant height,stem thickness,shoot dry weight and root dry weight were significantly higher in PSB treatments than in CK.After the inoculation with phosphate-solubilizing bacteria,photosynthesis indexes of grape were obviously higher than those of contrast plants.In conclusion,the inoculation of phosphate-solubilizing bacteria could significantly promote the growth of Cabernet sauvignon.Among all these inoculation methods,the best is JYR-12.
