Glasshouse experiments were conducted twice to assess the ash amendments (0, 20, and 40% with soil), a phosphate solubilizing microorganism Pseudomonas striata and a root-nodule bacterium Rhizobium sp on the reproduction of root-knot nematode Meloidogyne incognita and on the growth and transpiration of pea. Amendments of fly ash with soil had no effect on transpiration. However, M. incognita reduced the rate of transpiration from 1st week onward after inoculation while inoculation of Rhizobium sp and P. striata increased transpiration from 1st week onward after their inoculation both in nematode inoculated and uninoculated plants. Increase in transpiration was greater when both organisms were inoculated together. Addition of 20 and 40% fly ash with soil was beneficial for plant growth both in nematode inoculated and uninoculated plants. Inoculation of above organisms also increases plant growth of nematode inoculated and uninoculated plants in different fly ash soil mixture but increase in growth was greater when both organisms were inoculated together. Use of 20% fly ash increased galling and nematode multiplication over plants grown in without fly ash while 40% fly ash had adverse effect on galling and nematode multiplication. Rhizobium sp had greater adverse effect on galling and nematode multiplication than P. striata. Use of both organisms together had greater adverse effect on galling and nematode multiplication than caused by either of them alone. Highest reduction in galling and nematode multiplication was observed when both organisms were used in 40% fly ash amended soil. However, highest transpiration was observed in plants without nematodes and inoculated with both organisms together both in with or without fly ash amended soil.
进行了两次温室试验，以评估灰分改良剂（与土壤混合比例为0%、20%和40%）、解磷微生物条纹假单胞菌和根瘤菌对根结线虫南方根结线虫繁殖以及豌豆生长和蒸腾作用的影响。粉煤灰与土壤混合对蒸腾作用没有影响。然而，接种南方根结线虫后，从第1周起蒸腾速率降低，而接种根瘤菌和条纹假单胞菌后，无论是否接种线虫，从接种后的第1周起蒸腾作用均增强。两种生物一起接种时蒸腾作用的增强更为显著。在接种和未接种线虫的植株中，添加20%和40%的粉煤灰与土壤混合对植物生长均有益。接种上述生物也能增加接种和未接种线虫的植株在不同粉煤灰土壤混合物中的生长，但两种生物一起接种时生长增加更为显著。使用20%的粉煤灰会使植株上的虫瘿和线虫繁殖比不使用粉煤灰的植株更多，而40%的粉煤灰对虫瘿和线虫繁殖有不利影响。根瘤菌对虫瘿和线虫繁殖的不利影响比条纹假单胞菌更大。两种生物一起使用对虫瘿和线虫繁殖的不利影响比单独使用其中任何一种更大。在40%粉煤灰改良土壤中同时使用两种生物时，观察到虫瘿和线虫繁殖的减少最为显著。然而，在有或没有粉煤灰改良土壤的情况下，未接种线虫且同时接种两种生物的植株中观察到蒸腾作用最强。
