| 摘 要： | There is great potential for agriculture in saline-alkali soil area in Songnen Plain, Northeast China. Butthe sustainable crop production in this area has been restricted by a few of main factors, such as less precipitation, higherevaporation and frequent drought, high salinity and alkalinity, high exchangeable sodium content and poor infiltration ofthe soil, and insufficiency and low availability in nutrition. It is also considered that there are a few of favorable condi-tions for agricultural development in this region, such as sufficient light and heat resources, rich ground water resources,plenty of manure produced by livestock, and so on. At the same time, scientific management and measurements havebeen employed; rational irrigation and drainage system has been established; reclamation, amendment and fertilization ofsoil, and suitable strategies of cropping practices have been made for the sustainable development of agriculture. Great progress has been made during 1996- 2000.

| Abstract: | There is great potential for agriculture in saline-alkali soil area in Songnen Plain, Northeast China. But the sustainable crop production in this area has been restricted by a few of main factors, such as less precipitation, h igher evaporation and frequent drought, high salinity and alkalinity, high excha ngeable sodium content and poor infiltration of the soil, and insufficiency and low availability in nutrition. It is also considered that there are a few of fav orable conditions for agricultural development in this region, such as sufficien t light and heat resources, rich ground water resources, plenty of manure produc ed by livestock, and so on. At the same time, scientific management and measurem ents have been employed; rational irrigation and drainage system has been establ ished; reclamation, amendment and fertilization of soil, and suitable strategies of cropping practices have been made for the sustainable development of agricul ture. Great progress has been made during 1996-2000. |
