为了缓和杂交玉米制种田、亲本繁殖田与大田在安排作物布局上的矛盾,现根据国外种子田的规程标准和辽宁等地国内试验研究资料,提出玉米制种田和自交系繁殖田的隔离标准,供讨论参考。一、执行现行标准难度较大。杂交玉米制种和亲本繁殖田,采用空间安全隔离是保证种子质量的重要环节之一。种子质量的高低,不仅受距离、风速、风向、地形、屏障、污染粉源面积、制种繁殖
In order to alleviate the contradiction between hybrid maize farming, parental breeding field and field arrangement of crops, according to the rules and regulations of foreign seed fields and the domestic experimental research data of Liaoning and other places, the isolation standard of maize farming and inbreeding lines For discussion and reference. First, the implementation of the current standard more difficult. Hybrid corn seed and parent propagation fields, the use of space-safe isolation is one of the important links to ensure the quality of seeds. The level of seed quality, not only by the distance, wind speed, wind direction, topography, barriers, pollution powder area, seed multiplication
