对春玉米进行不同种植方式的增产增效对比研究,结果表明:全覆膜双垄沟播(T3)、半覆膜双垄沟播(T4)两种种植方式都有增温保墒的作用,是有效的抗旱保苗种植方式,宽窄行留高茬交替种植(T2)也有一定作用但不显著。T3和T4种植方式可有效提高早春干旱地区玉米的出苗率,改善植株性状和产量性状,从而能有效提高玉米产量。两者比较,全覆膜双垄沟播更优于半覆膜双垄沟播方式。此外,两种覆膜播种方式可以减少田间管理和浇水费用以减少投入,从而达到增收目的。
The results showed that both double-furrow sowing (T3) and double furrow sowing (T4) both had the effect of warming and preserving soil moisture, which was effective Drought-tolerant seedlings planting mode, the width of the row of high stubble alternate planting (T2) also has some effect but not significant. T3 and T4 planting methods can effectively improve the emergence rate of maize in early spring arid areas and improve plant traits and yield traits, which can effectively increase maize yield. Comparison between the two, the full film double ridge furrow sowing is better than the half ridge double furrow sowing method. In addition, the two kinds of film sowing methods can reduce the field management and watering costs to reduce input, so as to achieve the purpose of increasing income.
