以烘干粉碎后的秸秆与灭菌后的土壤配制成栽培基质,接种5种丛枝菌根菌种接种剂进行番茄栽培试验。结果表明,各种丛枝菌根共生微生物接种后对番茄幼苗生长发育和矿质元素吸收有很好的改善和促进作用,特别是对P、K吸收作用显著,对番茄干质量有明显增加作用。通过对番茄菌根侵染情况分析发现根部丛枝菌根侵染率(F)以Glomusmosseae-1和G.mosseae-2最高,可达30%以上,而丛枝菌根形成率(a)则以G.mosseae-2最高,促进番茄生长效果最好的菌种亦为G.mosseae-2。
The dried straw and the sterilized soil were used to prepare the cultivation substrate, inoculated with 5 kinds of arbuscular mycorrhizal inoculants for tomato cultivation. The results showed that the arbuscular mycorrhizal inoculation of various arbuscular mycorrhizal symbiotic microorganisms improved and promoted the growth of tomato seedlings and the absorption of mineral elements, especially the absorption of P and K, but significantly increased the dry weight of tomato. According to the analysis of mycorrhizal infection in tomato, the highest arbuscular mycorrhizal infection rate (F) of Glomus mosseae-1 and G. mosseae-2 was up to 30%, while the arbuscular mycorrhizal formation rate (a) G.mosseae-2 highest in the promotion of tomato growth is the best strain of G.mosseae-2.
