在鲁西地区,利用合理的栽培技术措施,把西芹种苗定植于大田,并使其安全越冬,翌年种株生长健壮,进人生殖生长阶段时种株达到半成株标准,抽薹早,开花期提前,结籽期延长。同以往芹菜制种采用年前育苗,冬季贮藏或假植,年后定植大田这种方法相比,现在采取的西芹制种方法,具有省工、管理技术简便、制种产量高、质量优等特点。具体制种方法如下: 1 培育适龄壮苗西芹是伞形花科两年生蔬菜,完成一个生长周期近一年。属于绿体春化型,即幼苗长到一定大小,具有4～5片叶子以上,在2～5℃低温条件下,经30～40
In the Luxi area, using rational cultivation techniques and measures, the celery seedlings were planted in the field and made it safe for wintering. The next year, the seedlings grew robustly. When entering the reproductive growth stage, the seedlings reached the semi-adult standard, with early bolting, Flowering in advance, the seed-end extension. Compared with the celery seed production method used in the past, such as seedling raising in previous years, storage in winter or fake-planting in winter, and field planting in the year, the method of planting celery now has the advantages of labor saving, simple management techniques, high seed yield and excellent quality Features. Specific seed production methods are as follows: 1 Cultivation of age-strong seedlings celery is Umbelliferae biennial vegetables, to complete a growth cycle of nearly a year. Belonging to the vernal vernalization type, that is, the seedlings grow to a certain size, with 4 to 5 leaves above, at 2 ~ 5 ℃ low temperature conditions, the 30 ~ 40
