Abstract:
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.
