Study on Application Effect of Maize Conservation Tillage Technology in Liaoyang Area
The research on conservation tillage was carried out in Liaoyang area.In the project area,the methods of uniform no-till seeding and wide-narrow no-till seeding were adopted,and the traditional shallow rotation seeding was set as the control.The results showed that the average seedling emergence rate of no-till maize was 83.83%,1.15% lower than that of the control;The average plant height was 398.40 mm,33.60 mm higher than that of control;From the results of production measurement,the uniform row and wide-narrow row no-tillage seeding mode increased the yield by 4.9% and 4.6%,respectively.
