大田接种丛枝菌根真菌对甘蔗品种“福农41号”生长的影响

摘要

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pH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。%To reveal the influence of inoculation of arbuscular mycorrhizal (AM) fungi on sugarcane, sugarcane variety Funong 41 grown in fields were inoculated with AM fungi, and the soil property and the plant growth were investigated. The results showed that AM fungi can stimulate sugarcane plants to absorb magnesium and organic matter, especially available phosphorus when inoculating AM fungi together with 50% compound fertilizer. Arbuscular mycorrhizal (AM) fungi inoculation increased soil pH value, stimulated the plant growth, and increased millable cane stalks, cane production and sugar contents.
