原苏联曾报道亚麻种子分级后的播种材料有增产提质效果。我国亚麻种植业实践证明,有的年份由于种粒均匀麻苗就整齐,毛麻率低,原茎产量高质量好。但多数年份由于使用混级种子播种,因生活力的差异,导致麻苗高矮不齐,粗细不均,熟期不一致。为了在同等栽培条件下,提高亚麻产质量,增加工农业的经济效益,亚麻种子分级势在必行。亚麻种子几何尺寸比较复杂,不如粮豆作物好分级。我们经过对千余粒种子长、宽、厚的测试分析。其宽度与体积或千粒重正相关,同级种
The former Soviet Union reported that seeding materials after flax seed grading have the effect of increasing production and improving quality. Flax cultivation in our country has proved that in practice, some of the years due to uniform seedlings Maize neat, Ma Ma rate is low, the high yield of good quality stems. However, due to the use of mixed-grade seed sowing in most of the years, the difference in vitality led to irregular height and uneven thickness and inconsistent maturity. In order to improve the quality of flax and increase the economic benefits of industry and agriculture under the same cultivation conditions, the classification of flax seeds is imperative. Flax seed geometry is more complex, not as good as grain crops grading. We have more than a thousand seeds long, wide, thick test analysis. The width and size or 1000 grain weight is related to the same species
