补充资料：垄作
| 垄作 ridge culture 在高于地面的土埨上栽种作物的耕作方式。中国华北、东北和内蒙古等地多用于栽培玉米、高粱、甜菜等旱地作物，其他地区主要用于栽培甘薯、马铃薯等薯芋类作物。垄由高凸的垄台和低凹的垄沟组成。其优点：垄台土层厚，土壤空隙度大，不易板结，利于作物根系生长；垄作地表面积比平地增加20％～30％，昼间土温比平地增高2～3℃，昼夜温差大，有利于光合产物积累；垄台与垄沟位差大，利于排水防涝，干旱时可顺沟灌水以免受旱；垄台能阻风和降低风速；利于集中施肥。垄的高低、垄距、垄向因作物种类、土质、气候和地势而异。作垄方法有整地后起垄和不整地直接起垄以及山坡地等高起垄。播种方法有种和扣种。
