过去,我们采用的小麦杂交法,是在整穗去雄后,一朵一朵花地进行人工授粉的。这种方法,工作量大,费工费时。近两年,我们借鉴墨西哥小麦杂交法,加以改进后,操作简便,省工省时,杂种结实率达70％以上。现将此法介绍如下:去雄:选择生长健壮的主穗或分蘖穗3—4个,在穗颈抽出叶鞘1厘米左右、花药青綠色时去雄,作为母本。去雄前,先剪掉基部和上部的小穗,留5—7排中间的小穗,每小穗只留基部的两朵小花,中部的小花用镊子夹除,然后剪芒(不剪 In the past, we used the method of wheat hybridization, after the whole ear is emasculated, one by one flower artificial pollination. This method, heavy workload, time-consuming work. In the past two years, after drawing lessons from the hybridization law of wheat in Mexico, we have made it easy to operate and save time and labor. The rate of cross-fertilization is over 70%. This method is now introduced as follows: Emasculating: Choose a robust main spike or tillering spike 3-4, about 1 cm in the panicle out of the sheath, green anthers when male, as the female parent. To go before the male, first cut off the base and the upper spikelets, leaving the middle of the spikelets 5-7 rows, leaving only the base of two small flowers per spike, the middle of the flowers with tweezers folder, and then cut Mans (not cut
