在生产上采用下列技术措施,能使有籽葡萄的种籽软化或败育,达到无籽、优质、早熟的效果。试验结果表明:葡萄无核率达98%—100%;果实含糖量提高2—3度;果实提早15—20天成熟。一、用“920”处理果穗。当葡萄果穗初步形成时,每亩取有效浓度4%的“920”25毫升或25克,用少许酒精溶解后加水20公斤,于葡萄始花期10—15天和盛花后5天内,用超低容量喷雾器盛药对准花穗反复均 In the production of the following technical measures can make the seeds of seed grapes softened or aborted to achieve seedless, high quality, precocious effect. The results showed that: grapes without nuclear rate of 98% -100%; fruit sugar content increased by 2-3 degrees; fruit mature 15-20 days earlier. First, use “920 ” handle ear. When the initial formation of grape berries, the effective concentration of 4% per acre take “920 ” 25 ml or 25 g, dissolved in a little alcohol and add water 20 kg, the grape flowering 10-15 days and 5 days after full bloom with Ultra-low-volume sprayer vials repeated spike alignment
