番薯与绿豆、矮菜豆、大豆和花生轮作大大提高了番薯的产量。其中番薯与绿豆轮作的增产最多。木薯与这些豆科作物轮作并不影响木薯的农学特性、产量和产量组分。芋头与花生轮作的增产量比其他处理的多得多。成本与收益分析表明,在用于轮作的豆科作物中,花生无论与番薯、木薯或芋头轮作,其净收益均最高。这证明花生与块根(块茎)类的作物轮作是最有利可图的轮作制度。
Sweet potato and mung bean, dwarf bean, soybean and peanut rotation greatly increased the yield of sweet potato. Which sweet potato and mung bean rotation yield the most. The rotation of cassava with these leguminous crops does not affect the agronomic characteristics, yield and yield components of the cassava. Taro and peanut rotation increased much more than the other treatments. Cost and benefit analysis shows that peanut has the highest net income among the leguminous crops used for rotation, both with sweet potatoes, cassava or taro rotation. This proves that the crop rotation of peanut and tuber (tuber) species is the most profitable rotation system.
