木薯和豇豆或花生间作对土地利用率和产量的影响鲜为人知。本研究旨在测定木薯、豇豆、花生在间作和单作时的土地利用率、产量和产量组分。木薯和豇豆或木著和花生间作使木薯减产2.3—4.7吨/公顷(1982年木薯和豇豆间作的结果除外)。1981年豇豆在与木薯间作时的产量比单作的产量少1025公斤/公顷,1982年减少899公斤/公顷。两年平均,花生在与木薯间作时的产量比单作的产量减少806公斤/公顷。尽管各种作物因间种而减产,但木薯与豇豆和木薯与花生间作制度在11个月生长期间的土地利用率却比单作制度高15—35％。这对于人均可耕地少的发展中国家确是很重要。
The impact of cassava and cowpea or peanut intercropping on land use and yield is poorly understood. The purpose of this study was to determine the land use efficiency, yield and yield components of cassava, cowpea and peanut during intercropping and single cropping. Cassava and cowpea or intercropping with peanuts reduced the production of cassava by 2.3-4.7 tons / hectare (except for the result of intercropping between cassava and cowpea in 1982). In 1981, the yield of cowpea during intercropping with cassava was 1025 kg / ha less than that of monoculture and 899 kg / ha in 1982. For a two-year average, peanut production decreased by 806 kg / ha when compared to single-crop production. Although crop yields were reduced by inter-cropping, the inter-cropping system for cassava and cowpea and cassava and peanuts achieved 15-35% greater land use during the 11-month period than monoculture. This is indeed important for developing countries with a small arable land per capita.
