【摘要】 为确定叶面肥1125对玫瑰(R osa rug osa T hunb)开花习性、适采期的影响,采用对比试验方法,以清水为对照,于2003年3月26日玫瑰新梢两叶期喷施叶面肥1125。结果表明:喷施叶面肥1125的玫瑰初花期比对照提前2.5~3.0 d,开花集中,盛花期由6 d缩短到3 d,花期延长2~3 d。经1125处理的玫瑰整个花期比对照长5~6 d。经1125处理的玫瑰单株总花量多于对照,差异达极显著水平;单株花总鲜重、总干重,单花鲜重、干重与对照相比,差异均达极显著水平。经1125处理的玫瑰,无论是干花还是鲜花,适采期均为蕾期,比对照提前1天。更多还原

【Abstract】 In order to determine the effect of foliar fertilizer on the habit and characteristic and the optimal picking period of Rosa rugosa Thunb,foliar fertilizer 1125 was sprayed in two-leaf stage of the new top on March 26 th,2003.The experiment was carried out by the way of correlation experiment and the water was used as the contrast.The results showed:The start-bloom stage of Rosa rugosa Thunb sprayed with 1125 was 2.5～3.0 d earlier than that of the contrast.Moreover,the full-bloom stage was shortened from 6 d to 3 d,the period of blooming was extended by 2～3 d.The whole period of blooming of Rosa rugosa Thunb treated with 1125 was 5～6 d longer than that of the contrast.The whole number of flowers of a single plant treated with 1125 was more than the contrast,and the difference was remarkable.The total fresh weight,the total dry weight of a single flower,the fresh weight and the dry weight of a single flower were all heavier than the contrast,and the difference was remarkable.Whether the flowers of Rosa rugosa Thunb treated with 1125 were dry or fresh,the optimal period was the flower bud stage.更多还原
