Wang Ronghuan · Heilongjiang nongye kexue · 2012
The United States maize planting area and yield are the most in the world,whose researches on production,scientific research and extension are all advanced and scientific.Learning from their advanced technology and experience has will great practical significance for guiding China's maize production,especially for Heilongjiang maize production.Through an on-the-spot investigation on maize planting,scientific research and extension in Iowa and Nebraska,it concluded the United States maize production was: maize farming and cultivation system were more science,agronomy combined with farm machinery closer,using comprehensive transgenic maize varieties,scientific and reasonable fertilizer management,at the same time,a comprehensive intelligent direction to develop and enhance.So the enlightenment to China maize production were: agricultural machinery and agronomy should combine to meet actual;should promote protective farming efforts and reform of low yield field,culture fertilizer to increase soil organic matter;should carry out precision agricultural research and apply in practice to guide production;should strengthen research and application of transgenic technology,water-saving and benefit increasing technology;should promote Heilongjiang land scale operating,strengthen farmers training to improve quality;should strengthen researches on differences of maize yield potential and actual yield.
