Also rape seed yield per area in the mix cropping system was the highest. 间作与混作处理的油菜产量在可比面积上比油菜单作产量高，其中混作产量最高。
Thus there should be studies for finding an optimal fertilizer schedule based on a cropping system including intercropping systems rather than for a single crop only. 因此，应该研究包括间作在内的种植制度而不仅为某种作物寻找合适的施肥方案。
