由于铁岭市地处辽宁省北部,积温和日照光热资源比照辽宁省中部和南部稻区明显不足,目前水田生产发展不平衡,存在着一些栽培技术上亟待改进的环节,如品种选择、育苗粗放、肥水管理等方面的实际问题,制约了辽北地区水稻产量的进一步提升。基于此,分析水稻栽培存在的一些常见问题,提出相应的解决对策。由于铁岭市地处辽宁省北部,辽北的光热资源比照辽宁省中部和南部明显不足,有一定的差距。具体而言,铁岭市各地种植水平不均衡,中部和南部稻区产量和管理水平稍好一些,东北部和山区等落后稻区仍存在诸多
Due to the fact that Tieling City is located in the northern part of Liaoning Province, accumulated light and sunlight are significantly less than those in the central and southern Liaoning Provinces. At present, there is an imbalance in paddy field production and there are still some urgent needs to be improved on cultivation techniques such as variety selection, , Fertilizer and water management and other aspects of the actual problems that restrict the further increase of rice production in northern Liaoning. Based on this, we analyzed some common problems existing in rice cultivation and put forward corresponding solutions. Due to the fact that Tieling City is located in the northern part of Liaoning Province, the light and heat resources in northern Liaoning are obviously deficient compared with the central and southern part of Liaoning Province, and there is a certain gap. Specifically, the planting level in various areas of Tieling is not balanced, the output and management level in the central and southern rice areas are slightly better, and there are still many backward rice areas in the northeast and mountainous areas
