本研究利用辽宁省铁岭市蔡牛镇玉米生产农户2018年与2019年两年的连续跟踪实地调研数据,对春玉米条带耕作密植高产技术的采用情况、经济效果进行分析,并基于随机前沿生产函数模型对农户玉米生产的技术效率进行评价。研究表明：种粮大户、合作社等有较大生产规模、农业收入占家庭总收入比重大、户主受教育程度较高的农户更倾向于采用技术,普通农户采用技术比例较低；不论是灾害年还是正常年,春玉米条带耕作密植高产技术都显著地提高了玉米生产农户的经济效益和技术效率,与正常年份比,春玉米条带耕作密植高产技术在灾害年份更能发挥提高经济效益、技术效率的优势。为此,政府应加大对该技术的宣传力度、提高农民专业素质、鼓励农户规模化经营、加大技术补贴力度以提高春玉米条带耕作密植高产技术的采用。

Using the tracked field survey data of corn producers in Cainiu town, Tieling city, Liaoning province in 2018 and 2019, the paper analyzed the adoption and economic effect of high yield technology of spring corn strip cultivation and close planting, technical efficiency was evaluated by stochastic frontier production function model method(SFA).The result is as follow: Those households with large production scale such as big farming household and cooperation were more likely to adopt the high yield technology .The households which were highly educated and whose agricultural income accounting for a large number of the total income were prone to adopt the high yield technology . The proportion of ordinary households adopting technology was low. The high yield technology of spring corn strip cultivation and close planting has significantly improved the economic benefit and technical efficiency of corn production. Compared with normal years, the high yield technology of spring maize strip tillage and close planting can play the advantages of improving economic benefits and technical efficiency in disaster years. Therefore, the government should intensify the propaganda of this technology, improve farmers" professional quality, encourage a large scale production, and increase technical subsidies to improve the adoption of the high yield technology of spring maize strip tillage and close planting.
