在苏联亚麻种植地区亚麻毒麦分布广泛,给许多亚麻生产单位造成很大损失。亚麻毒麦的颜色与亚麻植株十分相近,即使人工仔细除草也难于把亚麻毒麦从麻田中拔出。因此,亚麻种子清选在防除亚麻毒麦中具有决定性意义。亚麻毒麦颖果的质量与承风率几乎与亚麻种子相同,与亚麻种子不同的是毒麦颖果表面稍不光滑。根据这种特性,用ЗМС—1A型电磁选种机,可以在很大程度上把毒麦从亚麻种子中清选出去。在缺种的情 The widespread distribution of flax toxins in the flax area of ​​the Soviet Union has caused considerable losses to many flax production units. The color of flax toxin is very similar to that of flax plants, and it is difficult to pull the flax toxins out of the flax field even with careful weeding by hand. Therefore, the flaxseed clearance is of decisive importance in the control of flax. Flaxseed Mai Ying fruit quality and bearing the wind almost the same with the flax seeds, and flax seeds is different from the surface of toxic wheat crackers slightly dull. According to this characteristic, the toxic wheat can be largely removed from the flax seeds using the ЗМС-1A electromagnetic seeding machine. In the absence of love
