摘要
综合分析了冈优２２母本直播高产制种技术增产节支效果，对父母本主要特性和经济技术指标，以及对播差期安排，母本播管和“九二０”施用等高产制种技术关键作了阐述。
The effects of high-yielding seed production techniques of the medium hybrid rice Gangyou 22 with the female parent directly seeded on increasing yield and lowering cost were analyzed. The main characteristics of the parents and key points of the high-yielding techniques such as arrangement of seeding interval of the parents, seeding and management of the female parent and application of gibberellin were discussed.
