1造成种子质量纠纷的原因1.1种子质量因素1.1.1种子发芽率低在收获期种子水分含量高,脱水不及时,储藏不得当,影响种子发芽率,造成播种后田间出苗率低、出苗不整齐、苗势弱,遇不利天气或播种质量差时甚至不出苗。1.1.2种子纯度不达标种子纯度不达标,造成植株整齐度差,成熟期不一致,严重影响作物的应有产量,造成减产。种子纯度不达标主要是由生物学混杂和机械混杂等因素造成。生物 1 Causes of seed quality disputes 1.1 Seeds quality factors 1.1.1 Seeds germination rate is low In the harvest seed moisture content is high, dehydration is not timely, storage should not be, affecting the seed germination rate, resulting in low field emergence after sowing, sprouting irregularity , Miao weak, in adverse weather or seeding quality is poor or not sprout. 1.1.2 Non-compliance of seed purity Non-compliance of seed purity, resulting in poor plant uniformity, maturity is inconsistent, seriously affecting the crop yield, resulting in reduced production. Non-compliance of seed purity is mainly caused by such factors as biological confounding and mechanical confounding. biological
