超级稻垄栽与常规平栽宽窄行技术试验初报

Primary study on technology experiment of super rice ridge cultivated with conventional flat planting spacing

【目的】探索超级稻垄栽宽窄行的适宜插栽技术及对水稻产量的影响,发挥最大的增产效果,为今后大面积推广提供科学依据。【方法】进行了超级稻垄栽宽窄行种植和平栽宽窄行种植对比试验,试验田块面积:226.7m^2,对照田田块面积为320m^2。【结果】垄栽宽窄行试验比平栽田每667m^2增产136.91kg,以国家稻谷收购价2.9元/kg计,垄栽试验比平栽田多收入397.04元;增收节支397.04元,真正实现增产增效。【结论】超级稻实行垄栽宽窄行栽培是一项值得推行的超级稻高产栽培技术,特别适宜稻菜轮作地区推广种植。

[ Objective ] The present experiment was to explore the suitable technology of super rice ridge cul- tivated with conventional flat planting spacing and the influence on rice yield,try best to improve the yield, which provide a scientific basis for wide extension in future. [ Method ]The experiment conduct the compara- tive trial of ridge cultivated spacing and conventional flat planting, the area of experiment field is 226.7m2, while the area of contrast field is 320m2.[ Result ]The results showed that,compare with flare planting, the pro- duction of ridge cultivated spacing cultivated increase 136.91 kg per 667m2.[ Conclusion]The technology of super rice ridge cultivated and conventional flat planting spacing is a worthwhile high-yield cultivation tech- niques, particularly suitable for the area of rice-vegetable cabbage rotation system.
