1) Ridge rice field
垄作稻田
2) ridged-furrow
垄作区田
1.
As a soil conservation tillage method, ridged-furrow has been applied in sloping field.
垄作区田作为水土保持措施已在黑龙江省丘陵地区推广应用。
3) ridge plotted field
垄作区田
1.
ridge plotted field not only is a way of preserving water and soil, but also perfect soil-water environment and improve the yield of crops.
坐水种是一种较好的抗旱播种方法,苗期补灌技术也是一种旱地农业生产措施,垄作区田不仅是一项水土保持措施,而且也能改善土壤的水分环境,促使作物增产。
4) ridge tillage
垄作区田
1.
Based on the experimental study on the effect of combination technology of water saving and drought control, adopting the Statistical Analysis System (SAS),the author studied the influence of irrigation water and ridge tillage on the yield of maize, set up mathematical model of relation between yield ,irrigation water and ridge tillage.
以节水抗旱组合技术"机械化暗式坐水点播技术+机械化苗期补灌技术+垄作区田保水技术"的实施效果的实验研究为基础,采用SAS统计分析方法,对水分(播种期坐水量和苗期补灌水量)、垄作区田对玉米产量的影响进行了分析,建立了产量与水分、区田关系的数学模型。
5) paddy-field rotate
稻田轮作
1.
In the field experiment of five years in this paper, ecological analysis based on paddy-field rotate system and continuous cropping was studied in the view of soil physical and chemical characteristics, crop output variety, occurring and developing rule of plant diseases and insect pests of farmland, power-flow and state of equilibrium nutrient.
结果表明,与连作耕作制度相比较,在试验设计范围内,稻田轮作系统明显改善了土壤的理化性状,使得土壤随着耕种年限增加,容重下降,而孔隙度增加,固相比率下降,气相比率上升,气液比值增大,土壤通透性大大增强,有效阻止土壤次生潜育化和土壤酸化,提高土壤pH值。
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。
