本试验于1987～1988年在上海地区设施条件下进行。供试草莓品种为宝交早生。促成栽培于10月27日起苗定植,10月30日大棚覆盖两层聚乙烯薄膜,10月30日～2月25日夜间补充2小时光照。半促成栽培于11月23日起苗定植,12月22月开始保温。促成栽培草莓分别于11月12日、20日,11月20日、12月5日,12月5日、18日分三期喷布10ppm赤霉素溶液,以不喷为对照,每区10株,重复3次。结果第一、二期处理的植株生长状况明显好于对照和第三期赤霉素处理的植株,产量分别比对照高80.9％、78.1％,具有抑制促成栽培草莓休眠的效应。其草莓的平均果重都低于对照,但差异不显著。半促成栽培草莓于1月13日,27日用10ppm赤霉素处理,其叶柄长、叶面积和有效花数与对照无
The experiment was carried out in 1987 ~ 1988 in Shanghai facilities. Strawberry varieties for the examination of early and late students. Promote cultivation on October 27 seedlings planted October 30 shed covered with two layers of polyethylene film, October 30 ~ February 25 at night to add 2 hours of light. Half contributed to the cultivation of seedlings planted on November 23, December insulation began in December. Fertilization strawberries were sprayed on 10, 12, 20, November 20, December 5, December 5 and 18 respectively in three phases of spraying on November 12, 20, Strains were repeated 3 times. Results The plants in the first and second phases were significantly better than those in the control and the third gibberellic acid treatment plants. The yield was 80.9% and 78.1% higher than that of the control respectively, which had the effect of inhibiting the dormancy of cultivated strawberry. The average fruit weight of strawberry is lower than the control, but the difference is not significant. Half-cultivated strawberry on January 13, 27 with 10ppm gibberellin treatment, the petiole length, leaf area and the effective number of flowers and the control without
