1.
For instance, interplanting commercial crops, winter or early spring vegetables in interplanting space of wheat-maize rotation before maize seeding can increase returns significantly.
例如，在小麦玉米轮作中玉米播种前在套种带中插套经济作物、冬前和早春蔬菜可显著增加收入。
2.
In wheat-maize rotation, about60-75% of total P should be applied to wheat and about70% of total K to maize.
小麦-玉米轮作中，总磷的60~5%施于小麦，总钾的70%于玉米。
