为了加快化杀杂交小麦的推广应用,降低制种成本,提高制种质量,解决制种过程中出现的问题,现将我所近几年在陕西省杨陵、兴平、华县、三原等地制种中的技术要点总结如下:1.合理选择制种田块,防止天然混杂制种田块必须绝对安全隔离。在周围种植大量其它小麦品种时,隔离应在500米以上,有油菜和大麦隔离时,至少也应在200米以上。最好利用山、楼房、村庄等自然屏障隔离。
In order to accelerate the popularization and application of crossbreeding wheat, reduce the cost of seed production, improve the quality of seed production and solve the problems in the seed production process, now in recent years I have been in Yangling, Xingping, Huaxian and Mihara in Shaanxi Province The technical points of seed production are summarized as follows: 1. Reasonable selection of farming plots to prevent natural hybrid farming system must be absolutely safe isolation. When planting a large number of other wheat varieties around the isolation should be more than 500 meters, with rape and barley isolation should be at least 200 meters above. The best use of mountains, buildings, villages and other natural barrier isolation.
