草莓(Fragaria×Ananassa Duch.)在印度半干旱地区的土壤中种植，产量不佳。低有机碳和低磷(P)有效性，加上高磷固定，极大地影响P的有效性，即使是在外部应用。通过田间试验，研究了接种丛枝菌根(AM)真菌和施磷对微繁草莓Fragaria×Ana Nassa‘Pajaro’Pajaro的增产效果。研究了4种剂量的P(50、100、150和200 kg P·ha1)在高固磷能力和缺磷的情况下对AM的反应。收获时，除最高施磷量(200 kg·ha~(-1))外，所有接种株均具有较高的单株产量、单位质量、节数、较高的地上部干物质和地上部P含量。然而，AM对产量的反应随磷浓度的不同而不同。接种植株在150 kg·ha~(-1)条件下果实产量显著高于未接种植株，产量与未接种植株相当.
Strawberries (Fragaria ×ananassa Duch.) grown in alfisols of semiarid areas in India results in suboptimal yields. Low organic carbon and low phosphorus (P) availability, in addition to high P fixation, affects P availability drastically, even when it is applied externally. The benefit to the yield of micropropagated strawberry Fragaria ×ana nassa 'Pajaro' through inoculation with arbuscular mycorrhizal (AM) fungi and P application was examined in a field experiment. AM response was evaluated at four doses of P (50, 100, 150, and 200 kg P·ha1) in a high P-fixing capacity and P-deficient alfisol. At harvest, all inoculated plants, except those at the highest level of applied P (200 kg·ha1), had larger fruit yields per plant, unit mass, number of runners, higher shoot dry matter, and shoot P content. However, the AM response as measured by yield varied with P concentration. Inoculated plants had a significantly greater fruit yield when grown at 150 kg P·ha1, and the yield was comparable with uninoculated...
