“春种一粒粟,秋收万颗籽”的古诗句虽有文学夸张的成分,却可知我国古代劳动人民在漫长的农业实践中早已积累了丰富的良种繁殖经验。但纤维亚麻和一般农作物不同,其种子繁殖倍数低(多数良繁田仅10～15倍)。大面积生产上的采麻田也是种子田,且以生产原茎为主要目的,要在工艺成熟期收获,成熟度差籽粒不饱满,是加骤良种退化的主要因素之一。原部分亚麻种子田因密度低茎长的粗大,导致出麻率低、纤维粗硬,而降低纤维产、质量和经济效益。 Despite the exaggerated literary composition of the ancient poem “Spring Planting a Millet, Autumn Collecting 10,000 Seeds,” we can see that the ancient working people in our country have already accumulated rich experience in breeding in the long agricultural practice. However, unlike flax and other crops, the seed multiplication factor is low (only 10 to 15 times for most species). It is also one of the main reasons for the degeneration of elite in the field of crop cultivation. The original part of the flax seed field due to the density of stem length of the coarse, resulting in low rate of hemp, coarse fiber, and reduce fiber production, quality and economic benefits.
