杂交制种去雄是玉米种子生产的重要环节.常规的去雄方法,常使玉米制种去雄不及时,不彻底,产生部分伪杂种,从而降低了种子质量. 为探讨解决玉米制种去雄的质量问题和减轻去雄工作的部分劳务,我们于1984～1985年进行了不同带叶量提前去雄的试验。一、试验的基本方法在制种田内划定3个重复区组,品种为英64×系14,制种比例1:4,处理为去雄带1叶,带2叶,带3叶,每处理28平方米。以相邻的制种田常规除雄为对照.各处理及种子田拔蓼工作均于7月26日开始(玉米吐丝前)进行。各处理每间隔3天
Maize hybridization is an important part of the production of maize seeds.Experimental methods to de-maize, maize seed often go male or not, not complete, resulting in some pseudo-hybrids, thereby reducing the seed quality.To explore the maize seed to go Male quality problems and to alleviate some of the labor-deprivation work, we carried out in 1984 to 1985 with different amount of leaves to pre-test the male. First, the basic method of experiment In the system of farming delineated three repeat groups, the varieties of the British 64 × line 14, seed production ratio of 1: 4, to deal with the male with a leaf, with 2 leaves, with 3 leaves, each Processing 28 square meters. The conventional farming system was used to remove the male as the control, and the treatments of all the treatments and the planting of Polygonum orientale were started on July 26 (before corn spinning). Each treatment every 3 days
