吉林省湿润冷凉区通过3种旋耕灭茬起垄机播种玉米的试验,筛选出旋耕灭茬起垄机播种玉米的最佳机械。结果表明,处理3比处理1和处理2的灭茬率分别提高7.0%和9.5%,出苗率分别提高9.0%和11.0%,处理3的机械播种玉米的效果明显提高。处理3比处理1、处理2分别增产904 kg/hm2、975 kg/hm2,产值分别提高1 808元/hm2、1 950元/hm2。明确处理3的机械为该区域旋耕起垄灭茬播种玉米的最佳机械。
Jilin Province, humid and cool area by three kinds of rotary tillage machine sowing corn cultivation test, screened rotary tillage ridging machine sowing the best corn machinery. The results showed that the stubble ratio of treatment 3 and treatment 2 increased 7.0% and 9.5% respectively, the germination rate increased 9.0% and 11.0% respectively, and the effect of mechanical sowing maize 3 was obviously improved. Treatment 3 and treatment 2 increased yields by 904 kg / hm2 and 975 kg / hm2, respectively, and the output value increased by 1 808 yuan / hm2 and 1 950 yuan / hm2, respectively. Clearly deal with the 3 machinery for the region rotary ridging crop cultivation of corn crop the best machinery.
