近年来,随着农村种植业结构凋整的不断深入,相应带来了杂交稻种市场竞争加剧,一些应用时间较长的杂交组合由于品种老化、米质较差、抗性较弱等原因将逐步被淘汰,而产量高、米质优、抗性强的杂交组合仍然供不应求,成为广大经营客户和农民朋友的抢手货,但有些新组合因为受到气候、地理等因素的限制,育种地不能大面积制种而直接影响其推广速度,只能异地生产来满足市场需要。不过异地制种无论在种子产量上,还是在种子质量上,都有较大的风险,要想获得成功,笔者认为应该注意以下几方面的问题:
In recent years, with the continuous deepening of the structural adjustment in rural areas, the competition in hybrid rice varieties has been correspondingly intensified. Some of the hybrid combinations with longer application time, due to aging varieties, poor quality and weak resistance, Gradually eliminated. However, the hybrid combination with high yield, high quality and strong resistance is still in short supply and has become a hot commodity for the majority of business customers and peasant friends. However, some new combinations can not be bred due to climate, geography and other factors Seed production and directly affect the speed of its promotion, only off-site production to meet market needs. However, seed production in different places, both in seed yield, or in the quality of the seeds, have a greater risk, in order to be successful, I think we should pay attention to the following aspects:
