我们在棉花杂种优势利用研究中,通过学习外地经验,对传统的人工剥花去雄授粉法进行了改革,摸索出一套雌雄蕊麦秆隔离吸管授粉的杂交新方法,工效和质量显著提高。具体作法:取直径4—5毫米,长约35—40毫米无节小麦秆,于清晨5时至7时半棉花花药开裂前,将麦秆沿花柱插下,使花丝花药与柱头彻底隔离。上午8时待父本花药开
In our study on the utilization of cotton heterosis, we learned from the experiences of other countries to reform the traditional manual pollination and pollination method and found out a new hybridization method of pollination of stamen and straw isolation straw. The work efficiency and quality of the pollination method were significantly improved. Specific practices: take diameter 4-5 mm, about 35-40 mm sectionless wheat straw, early in the morning 5 am to 7:30 cotton anther before cracking, the straw along the style inserted, so that filigree anthers and stigma completely isolated. 8:00 am to be open to the male parent anther
