摘　　要：上海地区的桃(Prunus persica(L.)Batsck)果实受环境条件的影响,缝线处及果顶部易发生青斑或烂顶。研究表明,在桃硬核期前用B_92000ppm喷洒2—3次,并配合深沟排水,降低地下水位,可有效地克服这类生理病害的发生,并能使果实圆正,成熟期提前,采收期较集中,色泽鲜艳,贮藏期延长。In Shanghai area, owing to the climatic influence, the fruit of many peach cultivars colored poorly, ripened not uniformly, i. e., the flesh of the sut ure at the top of the fruit showed more advanced maturity and became soft.Furthermore, green spots and top-rot of the fruits occurred at the suture and top respectively. Fruits showing green spots or those ripened not uniformly reached senescence very quickly, turned brown and decayed rapidly. Three peach cultivars, 'Canning Peach No.5', 'Jinxiu' and 'Yulu' were used as experimental materials. Foliar application of Alar at ?the rate of 2000 ppm after 40 days full bloom , sprayed 2-3 times at about 10-day interval, together with deepening the drainage ditches to lower the ground water table, corrected these disorders. The fruits ripened uniformly with excellent color, enhanced firmness and prolonged storage life due to delayed onset of senescence.
