近年,磐石市大部分地区低温多雨,异常的低温抑制了玉米种子的萌发与幼苗的生长,土壤水分过大,通透性差,种子长期处在厌氧状态下,加大了自身养分的消耗,活力降低,抵御病害能力差,造成粉种、烂种现象增加,出苗率低,根腐病加重,畸形苗增多。幼苗生长缓慢,新陈代谢功能弱,分解药害能力下降,加重了药害的表现。各地玉米普遍出现出苗不好、病害、药害、缺素症等现象。
In recent years, most parts of Panshi are characterized by low temperature and rainy and abnormal low temperature, which inhibit the germination of maize seeds and the growth of seedlings. The soil moisture is too large and the permeability is poor. Under long-term anaerobic conditions, the seeds increase their nutrient consumption, Reduced vitality, poor resistance to disease, resulting in powder, rotten phenomenon increases, the emergence rate is low, root rot, malformations increased. Seedling growth is slow, the metabolism is weak, the ability to decompose phytotoxicity decreased, aggravating the performance of phytotoxicity. Common emergence of maize emergence is not good, disease, injury, deficiency and other phenomena.
