1野生麦的形成途径1.1小麦分离退化野生麦发生的根本原因是由小麦生物特性和生态条件限制引起的分离退化而产生,因此其生物特性具有明显的野生性。在连作麦田这种现象发生更为普遍,其他茬口麦田较少。连作麦田多年种植小麦,一些野生麦种子成熟后掉落田间,其发生量逐年积累,出现连作麦田野生麦丛生现象,如不加以防治,会与繁殖品种争肥争水争空间,影响种子产量和质量。
1 formation of wild wheat pathway 1.1 wheat separation and degradation of wild wheat is the root cause of wheat biological characteristics and ecological conditions caused by the separation and degradation resulting from its biological characteristics of the obvious wild. The phenomenon of continuous cropping of wheat is more common, with fewer stubble wheat fields. Continuous cropping of wheat for many years planting wheat, some wild wheat seeds fall into the field after maturity, the amount of accumulation year after year, there is continuous cropping of wheat in the phenomenon of wild wheat, if not to be controlled, will struggle with breeding varieties of water and fight for space, affecting seed yield and quality.
