在 ６ 年生藤稔葡萄花后 ５ ｄ，果穗喷布 ５０～４００ ｍ ｇ／ Ｌ 的 吲熟酯，疏果率达 到 １１６％ ～４３７％ ，且浓度越高，疏果率越高，但浓度达到 １００ ｍ ｇ ／ Ｌ 时，出现药害 于盛花期、谢花末期、花后 ５ ｄ 分别喷布５０ ｍ ｇ／ Ｌ 的 吲熟酯，疏果 率达 １１８％ ～４００％ ，喷布时 间越早，疏果 率越高，其 中谢花 末期 喷布的 疏果率与 人 工疏 果 相似 ，同 时单 果 重增 加 ３９１ ～６３８ ｇ， 可 溶性 固 形 物提 高 １３％ ～ １９％ ， 含 酸量 降 低０２９％ ～０４８％ ，果实商 品价值显 著提高 据 对盛花期 喷布 ５０ ｍ ｇ／ Ｌ 的处 理调查 分析，吲 熟酯使 藤稔葡萄幼果内乙烯与 Ａ Ｂ Ａ 的含量分别提高 ７５０％ ～１１６７％ 和 ６８８％ ～１６６８％ ，从而加速幼果的脱落，落果高峰比对 照提前 ２ ｄ 出现 从疏果程度与 果实品质 两方面考 虑，生产上 应选谢花末 期喷布吲 熟酯５０ ｍ ｇ／ Ｌ 为宜 On the 5th day after 6-year-old Fujiminori grapes, spraying 50-400 m g / L indomethacin on the ears, the fruit-thinning rate reached 11.6% -43.7%, and the higher the concentration, the higher the fruit thinning rate However, when the concentration reached 100 m g / L, phytotoxicity occurred. At the end of full flowering and Xiehua stages, 50 m g / L indomethacin was sprayed on the 5th day after flowering, the fruitless rate was 118% ~ 40  0%. The earlier the spraying time, the higher the fruit thinning rate. The fruit thinning rate was similar to the artificial fruit thinning at the end of the flower arrangement, while the fruit weight increased by 3.91-6.38 g and the soluble solid content increased by 1  3% ~ 1  9%, acid content decreased 0  29% ~ 0  48%, the value of the fruit products increased significantly  According to the full bloom flowering 50 m g / L of the treatment of investigation, The contents of ethylene and A B A in grape berries increased by 750% -1167% and 688% -1668% respectively, which accelerated the shedding of young fruits  considered from both the degree of thinning fruit quality fruit drop peaked earlier than according to 2 d, should be selected on the production of spraying Shabana end indazol cooked ester 50 m g / L preferably
