辽西风沙半干旱区发展马铃薯膜下滴灌的探讨

Discussion on Dripping Irrigation under Film of Potato in the Sandy and Semi-drought Area of Western Liaoning

马铃薯(Solanum tuberosum L.)膜下滴灌技术是一种新型高效节水旱作农业灌溉技术在马铃薯栽培生产上的应用,符合现代农业对机械化、信息化和智能化的要求。在辽西风沙半干旱区发展马铃薯膜下滴灌对该区经济增收和产业调整有重要的现实意义。该文从膜下滴灌技术特点着手,指出辽西风沙半干旱区发展马铃薯膜下滴灌将要面临成本高见效慢、种植户分散推广难、设备管理及技术不成熟等实践性问题,建议在政府投入、土地集中管理和技术培训等方面应进一步加大力度,同时认为马铃薯将会成为辽西风沙半干旱区农村发展特色产业中最有开发潜力的高产经济作物。

Drip irrigation under film technology is the application of a new high efficiency water-saving and dry farming irrigation technology in potato production, it accords with mechanization and information and intelligent demand of the modern agriculture. Developing drip irrigation under film is still of vital realistic significance for us to increase the income and adjust industry in the sandy and semi-drought area of western Liaoning. According to the characteristics of drip irrigation under film technology, the present problems would face was pointed out, which were high cost and slow effect, planters dispersion and hard popularization, equipment management and immature technologies. Then the corresponding suggestions of enlarging government investment,land concentration management,strengthening technical training were proposed,and confirmed that potato would become the most potential economic crop for the characteristic industry of agriculture development in the sandy and semi-drought area of western Liaoning.
