从福建龙眼根际土壤中，发现了一个VA根真菌优势种（种名待定），在此基础上进行了扩繁培养和生长效应的研究。初步结果表明，以优势种孢子接种龙眼幼苗，然后以侵染成功的龙眼幼苗作为过渡，套种红三叶草，能大大提高红三叶草的侵染成功率，这是在本省环境条件下，进行优势种扩繁培养的一条可行途径。盆栽接种试验初步表明，优势种能促进龙眼对磷的吸收，从而促进幼苗的生长。
From the rhizosphere of Fujian Longan, we found a dominant species of VA root fungi (species name to be determined), on the basis of expansion propagation and growth effects. The preliminary results showed that inoculation with the dominant species of spores of longan seedlings, and then with the success of the longan seedlings as a transition, intercropping red clover, can greatly improve the success rate of red clover infection, which is under the province’s environmental conditions, the expansion of the dominant species A feasible way to cultivate. Pot experiment showed that the dominant species could promote the absorption of phosphorus by longan and promote the growth of seedlings.
