摘　　要：为探讨绿豆/黑豆还田和减施化肥条件下,间作绿肥压青还田对宿根甘蔗生长的影响及绿肥还田和有机肥施用对化肥的替代作用。试验设计了常规施肥(CK)、化肥减施25%+12%营养元素当量绿豆绿肥还田+13%营养元素当量有机肥(H-LY)、化肥减施25%+全量绿豆还田(H-LQ)、化肥减施25%+25%营养元素当量有机肥(H-Y)、化肥减施25%+25%营养元素当量黑豆绿肥还田(H-HD)和化肥减施25%+全量黑豆还田(H-HQ)6个处理。结果表明,与CK处理相比,宿根蔗间作绿豆和黑豆压青还田对甘蔗株高、有效茎数和单茎重没有显著影响,所有处理的蔗茎产量与CK处理无显著差异,说明宿根蔗间作绿豆和黑豆绿肥压青还田、当量有机肥施用均可以替代25%的甘蔗化肥。The impact of intercropping green manure returning to the field on the growth of ratoon sugarcane and the substitution of chemical fertilizer were further discussed under the condition of reducing the application of chemical fertilizer on the basis of new sugarcane intercropping mung bean/black bean. Conventional fertilization(CK) was the control, and the other five treatments lowered chemical fertilizer by 25% and substitution in other ways substitution by 12% nutrient element equivalent from green mung bean and 13%nutrient element equivalent from organic fertilizer(H-LY), substitution by full amount of green mung bean returning to the field(H-LQ), substitution by 25% nutrient element equivalent from organic fertilizer(H-Y),substitution by 25% nutrient element equivalent from green black bean returned to the field(H-HD) and substitution by full amount of green black bean returning to the field(H-HQ). The results showed that there were no significant effects on sugarcane plant height, number of productive tiller, weight of single stem compared with CK treatment. There was no significant difference in cane yield between all treatments. It indicated that intercropping with green manure between ratoon sugarcane line and returned it to the field combined with nutrient element equivalent from organic fertilizer could substitute 25% of sugarcane chemical fertilizer.
