摘　　要：为了探究德江县八月瓜果园种植绿肥鲜草还田对果园产量、收入及耕地质量的影响效果,试验以箭筈豌豆作为绿肥作物,设置了4个施肥处理,分别为优化施肥+绿肥不还田、减量5%施肥+绿肥压青还田、减量10%施肥+绿肥压青还田、减量15%施肥+绿肥压青还田,每个处理设3次重复,其余栽培管理措施一致。试验结果:重复间产量差异不显著,处理间产量差异显著,且随着实施时间延长,处理2从增产不显著到极显著,处理3从负增产到增产显著,处理4从负增产到增产不显著;种植绿肥压青还田可以提升八月瓜果园的耕地质量;种植绿肥压青还田可以减少15%的化肥投入,实施2年所有绿肥压青还田处理均实现了增收。This study explores the impact of incorporating fresh green manure into the soil on orchard yield,income,and soil quality at the August melon orchard in Dejiang County.The experiment utilized jack bean as the green manure crop.Four fertilization treatments were implemented:optimized fertilization without green manure incorporation,and reduced fertilization with crushed green manure incorporation at reductions of 5%,10%,and 15%.Each treatment was replicated three times,maintaining consistent other cultivation practices across all treatments.Results indicated no significant differences in yield among the repetitions;however,there were significant differences between treatments,with yields showing significant increases over time:Treatment 2 progressed from no significant increase to a highly significant increase,Treatment 3 from a decrease to a significant increase,and Treatment 4 from a decrease to a non-significant increase.The incorporation of crushed green manure into the soil has enhanced the soil quality of the August melon orchard.Additionally,the use of green manure enabled a 15%reduction in chemical fertilizer input,and after two years,all treatments involving green manure incorporation achieved increased income.
