做好玉米种子的脱水工作是保证玉米种子质量的一个重要方面。脱水问题解决不好,会降低种子发芽率,直接影响质量。针对脱水保质的问题,我们提出了“一割”、“一超前”、“四上”的脱水保质措施,收到了良好的效果。 “一割”就是在父本完成授粉后,及时割除,增强通风透光能力,促进早熟。 “一超前”就是超前站秆扒皮,对于晚熟的品种采取在乳熟末期站秆扒皮晾晒,平均每天降水0.2～0.5%。 “四上”就是改过去的大堆晾晒为因地制宜地挂秆、上房、上树、上墙,对于苞叶特短或苞叶掉 Doing the dehydration of corn seeds is an important aspect to ensure the quality of corn seeds. Dehydration problem is not solved, will reduce the rate of seed germination, a direct impact on quality. For the issue of dehydration durability, we put forward a “a cut ”, “an advance ”, “four ” dehydration quality measures, received good results. “A cut ” is cut off in time after the completion of pollination of the male parent, enhance the ability of ventilation and light, and promote premature. “An advanced ” is the advance station stalk skin, for the late varieties to take the end of the milk stalks flatter skin drying, the average daily rainfall of 0.2 to 0.5%. “Four on ” is to change the past, a lot of drying to hang for the local conditions stalk, on the room, on the tree, on the wall, for bracts short or bracts leaves out
