吉林省西部低洼盐碱地稻、苇、鱼开发模式的研究

Climate Becoming Warmer Influences to Agricultural Production in Jilin Province

摘要:

本文报道了1994~1995年大安市叉干镇科技示范区低洼盐碱地稻、苇、鱼开发模式的试验结果。试验面积7.27hm²，采取稻田养鱼(3.77hm²)、苇塘养鱼(1.92hm²)、泡沼养鱼(1.58hm²)、综合利用稻田排水及塘泥返田等措施，水稻、芦苇平均单产分别为6693.6kg/hm²及9320.3kg/hm²;稻田、苇塘及泡沼养鱼的净产量分别为580.4、2523.3及3892.5kg/hm²。单位土地面积纯经济效益平均12868元/hm²。还探讨了稻、苇、鱼模式的改土培肥、调节小气候、保护农业环境等生态效益。

Abstract:

Anaiyzing the atmosphere temperature datas of Jilin Province during 1909~1995 indi-cates that the climate of Jilin Province has being become warmer.Climate becoming warmer has caused change of agricultural production and increased crop yield. This paper put forward a proplsal about making further increase on agricultural production, paying attention to defending meteorological calamity, and protecting the climate environment.
