摘要 在印度尼西亚苏门答腊岛南端楠榜省的丘陵地区，咖啡通常种植在陡峭的山坡上，土壤侵蚀影响了咖啡的可持续生产。进行了为期 4 年的咖啡种植田间试验，以评估巷作和免耕对该地区陡坡地区咖啡种子生产和侵蚀控制的影响。当咖啡树还很小的时候，间作蔬菜、红辣椒、西红柿和长豆的种植就被引入了咖啡田。在处理之间，咖啡树或间作蔬菜的产量没有显着差异。然而，免耕处理使咖啡芽鲜重略有增加。由于免耕，土壤侵蚀减少了 37%，而小巷种植则减少了 64%。当地农民实行耕作+免耕处理的水土流失量是免耕+免耕处理的四倍多。这些结果表明，巷作和免耕对于陡坡咖啡田的侵蚀控制是有效的，并且产量不受这些做法的影响。引入间作蔬菜对农业经济有利，特别是在咖啡种植收入有限的情况下。
Abstract In a hilly area in Lampung State, the southern end of Sumatra Island in Indonesia, coffee is commonly cultivated on hillsides with steep slopes and soil erosion affects sustainable coffee production. A field experiment on coffee cultivation was conducted for 4 years to evaluate the effects of alley cropping and no-tillage on the seed production of coffee and on erosion control in a steep slope area in this region. The cultivation of intercropped vegetables, red peppers, tomatoes, and long beans was introduced into the coffee fields when the coffee plants were small. No significant differences in the yields of either the coffee plants or the intercropped vegetables were noted among the treatments. Coffee shoot fresh weight, however, was slightly increased by no-tillage treatment. Soil erosion was reduced by 37% as a result of no tillage and by 64% with alley cropping. The amount of soil erosion for local farmers practice, tillage & no-alley, was more than four times that in no-tillage and alley treatment. These results indicate that alley cropping and no-tillage are effective for erosion control on coffee fields on steep slopes and that yield is not affected by these practices. The introduction of intercropped vegetables is beneficial in terms of farm economy, especially when the income from coffee cultivation is limited.
