- 摘要:
- 通过田间观察和对鸭跖草进行种子萌发试验，初步明确鸭跖草的生物学特性，在黑河地区鸭跖草5月中旬开始萌发，5月下旬鸭跖草进入出苗盛期。鸭跖草最适萌发温度为15℃；最适发芽土壤含水量40%；最适发芽深度5～10 cm。
- Abstract:
- In order to provide theoretical basis for a safe and effective method，a series of experiments on germination of dayflowers were conducted.The result showed that germination of dayflower began at the middle ten days of May，mushrooming from the last ten days of May.When temperature was 15℃，the soil water content was 40%，the sowing depth was 5～10 cm，the emergence rate was the highest.
