赤霉素(920),最显著的生理效应是促茎叶的伸长。芹菜施用赤霉素后,叶柄变粗,叶片增长多,产量提高20～30%。一、时期与浓度200ppm 赤霉素溶液,收获前30天,20天各喷1次;或30～50ppm 溶液收获15天连喷2次。二、配制赤霉素粉剂须先用酒精溶解,然后倒入定量水中配成相应浓度的溶液。1升水加赤霉素30、50、100毫克分别得到30、50、
Gibberellin (920), the most significant physiological effect is to promote the elongation of stems and leaves. Celery gibberellin, petiole thicker, more leaf growth, yield increased by 20 to 30%. First, the period and the concentration of 200ppm gibberellin solution, 30 days before harvest, 20 days each spraying 1; or 30 ~ 50ppm solution 15 days spray even spray 2 times. Second, the preparation of gibberellin powder to be dissolved in alcohol first, and then poured into quantitative water dubbed the corresponding concentration of the solution. 1 liter of water plus gibberellin 30,50,100 mg were 30,50,
