早春大棚芹菜生长发育规律研究

Growth Dynamics of Celery in Early-spring Greenhouse

为探索芹菜生长发育规律,选用示范园区最新育成的芹菜杂种一代"Y08-H11",对其质量、高度、叶柄长度、叶柄粗度、叶片数、发生分蘖数量和幼嫩花茎长等指标进行研究,结果表明,芹菜在定植后的前21d生长缓慢,22～63d生长迅速,最后7d生长又变缓。并且芹菜植株高度、叶柄第1节和第2节长度、叶柄宽度和厚度、叶片数出现速度与生长天数均呈线性相关。

The dynamics changes of the celery cultivar Y08-H11 were studied in order to study the weight,height,length and diameter of leafstalk,the number of leaves,the number of tillers and the length of young stem. The results showed that the development process of celery could be approximately divided into three periods. The first period was the first 21 days after planting,the plant grew slowly. The second period was from the 22nd day to the 63th day,the plant grew rapidly. The last period was from the 64th day to harvest,the plant grew slowly. The growth of plant height,growing speed,length,width and thickness of leafstalk showed liner relation with growing days.
