为了探讨大田甘蔗接种丛枝菌根(AM)真菌促进甘蔗生长的效果,本研究对甘蔗品种“福农41号”进行大田接种AM菌剂的试验,初步分析其对甘蔗生长的影响。研究结果表明:AM菌剂能促进甘蔗对土壤中Mg和有机质的吸收;在施用AM菌剂及50%复合肥(375 kg·hm-2)的条件下,能促进P的吸收,提高磷肥的利用率。施AM菌剂能提高土壤的p H值,促进甘蔗植株生长,增加甘蔗有效茎数,提高产量和含糖量。
In order to investigate the effect of sugarcane inoculation with arbuscular mycorrhizal (AM) fungi on the growth of sugarcane in sugarcane field in our country, the experiment was carried out to inoculate the sugarcane variety “FuNong41” with AM fungi in field and the effects on the growth of sugarcane were analyzed. The results showed that: AM fungi could promote the absorption of Mg and organic matter in soil by AM fungi; under AM fungi and 50% compound fertilizer (375 kg · hm-2), AM fungi could promote P uptake, Utilization rate. Shi AM fungi can improve soil p H value, promote plant growth in sugarcane, increase the effective stem number of sugarcane, increase yield and sugar content.
