摘要
为进一步完善玉米免耕栽培技术,集成适合马山县实际的多样化玉米免耕栽培技术模式,从2004年下半年至2007年上半年,连续3年6造进行玉米秸秆还田免耕栽培试验,结果表明,玉米秸秆还田免耕栽培具有改善土壤理化性状、培肥地力、减少水土流失、降低劳动强度和生产成本、提高玉米产量等作用;秸秆还田免耕栽培玉米平均产量达6965kg/hm2,比常耕栽培增产229kg/hm2,增产7.2%,平均节本增收1223元/hm2。
In order to improve the no-tillage cultivation techniques for maize, different types of no-tillage cultivation models for maize were integrated according to the practical situation of Mashan County. From the second half year of 2004 to the first half year of 2007, the maize straw-returning to field with no-tillage cultivation was carried out for six cropping seasons in three years. The results showed that maize straw-returning with no-tillage cultivation could improve the physical-chemical characteristics of soil and soil fertility, reduce soil erosion, decrease the labor intensity and production costs and increase the yield of maize, etc. The yield of maize reached 6965 kg/hm^2 on avarage, and it increased 229kg/hm^2 over the conventional tillage with an increase rate of 7.2%; the average increasing income and saving costs was 1223 yuan RMB/hm^2. Therefore, it had significant social economic benefits.
