污泥堆肥利用中AM对三叶鬼针草生长及Cu富集作用的影响
Arbuscular Mycorrhizal Effect on Bidens pilosa Growth and Heavy Metal Accumulation in Application of Sewage Sludge Compost
摘要
Abstract
A pot culture experiment was carried out to study the influence of Arbuscular mycorrhizal on the growth and Cu accumulation of Bidens pilosa. Six levels of sewage sludge compost(0%, 20%, 40%, 60%, 80%, 100%), two AM fungal inoculation and one nonmycorrhizal inoculum(CK)were applied to coastal saline soils. The results showed that the biomass of B. pilosa seedlings was increased significantly with the sludge content increasing, and at level 40%-80% sewage sludge compost the biomass of inoculated seedlings was significantly higher than that of non-inoculated seedlings. Mycorrhizal infection rate at level of 20%-80% sewage sludge was increased significantly by inoculated with 2 AM fungi. Cu concentration of inoculated plant roots was significantly increased at level of 0%～60% sewage sludge, there was no significant difference in high proportion of sewage sludge between inoculated and non -inoculated plants. Cu accumulation of plant root was significantly increased when B. pilosa seedlings were inoculated with AM fungi, and Cu accumulation of inoculated plant roots was 3-4 times of plant shoots. These results indicated that AM fungi could promote the Bidens pilosa's growth and enhance to uptake heavy metal ions Cu.关键词
