东北地区水稻机械化种植模式

The Mode of Rice Mechanized Planting in the Northeast of China

为解决东北地区年积温小、水稻安全生长期短、种植模式多样化等特点对水稻机械化种植模式影响的问题，通过对东北地区水稻种机械化种植模式中的机插秧、机直播、机抛秧进行对比分析，并采用一种钵苗行栽技术，实现了钵苗的有序浅栽，增产增效效果显著。田间试验表明，钵苗行栽技术满足水稻种植的农艺要求，增产8％～10％，比常规人工种植节约成本约20％。研究认为，机械化插秧与钵苗行栽是2种适合东北地区的水稻种植模式，对该地区水稻机械化种植有一定的促进作用。

Analysis and contrast of rice transplanting, direct seeding, seeding throwing was studied and rice mechanized potted-seedling transplanting was proposed. This planting mode could make rice growing orderly and increase rice yield. Field experiment showed rice mechanized potted-seedling transplanting could meet the agronomic requirement of rice with 8% - 10% increase of yield and 20% decrease of cost compared with the traditional manual planting. Rice transplanting and rice mechanized potted-seedling transplanting are Suitable to the northeast of China.
