摘  要:
通过对鸭跖草进行种子发芽、出苗和抗逆性试验,初步明确了鸭跖草的生长发育规律,鸭跖草种子适宜的发芽温度为10~15℃;出苗的适宜深度为3~8 cm,深度20 cm以上不出苗;出苗的适宜土壤含水量为40%;鸭跖草在4叶期以前抗逆性较差,4叶期以后抗逆性增强;鸭跖草前期生长较慢,从第4、5叶龄开始生长速度加快。

摘  要:
In order to provide theorietics basis for a safe,economical and effective controlling method,a series of experi-ments on the germination of dayflowers were conducted by the authors.The growth and development laws of dayflower as follows:the seeds of dayflowers germinated at the temperature around 10~15℃ and at the depth of soil 3~8 cm.If the depth was over 20 cm,the dayflower failed to germinate.The proper soil moisture content for germination should reach 40%.The antireversion force of the dayflower is weak before four-leaf stage and it would become stronger afterwards.The prophase of the dayflowers growth was much slow,whereas it reached the four-leaf or five-leaf stage its growth speed accelerated.
