摘　　要：本文结合荃香优89生产实践,总结分析了其特征特性、适宜种植区域、栽培技术要点及高产制种技术。该品种在长江上中下游地区种植,表现出生育期适宜、米质优和产量高等特性;其适宜在四川省平坝丘陵稻区、云南省中低海拔籼稻区等稻瘟病低发地区种植。高产栽培技术包括适时早播、培育多蘖壮秧;重施底肥,及时追肥;干湿交替管水以及适时病虫害防治等。高产制种技术包括在海拔250~500m地区烟后制种;根据制种季节不同,确保父、母本播差期在6.5~7.5叶;药剂浸种、喷施多效唑等,以促进秧苗健康、矮壮和多分蘖;安排父母本行比为1∶8;根据田间秧苗生长情况进行肥水管理;根据田间实际调查情况和当地病虫害测报及时防治穗颈瘟、稻飞虱等病虫害;采取幼穗剥查法预测花期,以幼穗分化初期父、母本同期为宜;见穗15%时喷施赤霉素;制种全过程注意除杂保纯;75%籽粒黄熟时开始收割,收割后及时烘干。本文为荃香优89高产制种技术示范推广提供参考。The characteristics,suitable planting areas,cultivation techniques,and high-yield seed production techniques of Quanxiangyou 89 were summarized and analyzed based on its production practice.This variety is planted in the upper,middle,and lower reaches of the Yangtze River and exhibits characteristics such as suitable growth period,excellent rice quality,and high-yield;it is suitable for planting in areas with low incidence of rice blast disease,such as Pingba hilly rice growing areas in Sichuan Province and mid to low altitude indica rice growing areas in Yunnan Province.The high-yield cultivation techniques include early sowing in time and cultivating multi-tiller seedling;heavy application of bottom fertilizer,timely topdressing;dry and wet alternate pipe water and timely pest control.High-yield seed production techniques include post tobacco seed production in areas with an altitude of 250-500 meters;according to the different seed production seasons,ensure that the parental sowing difference period is between 6.5 and 7.5 leaves;soaking seeds with pesticides,spraying paclobutrazol,etc.,to promote the health,dwarfism,and multiple tillering of seedlings;arranging a parent to parent ratio of 1∶8;managing fertilizer and water according to the growth of seedlings in the field;timely prevention and control of diseases and pests such as neck blight and rice planthopper based on actual field investigations and local pest and disease reports;adopting the method of young ear peeling to predict flowering period,it is advisable to use the same period as the parents in the early stage of young ear differentiation;spraying gibberellin when the panicle reaches 15%;pay attention to removing impurities and maintaining purity throughout the entire seed production process;harvesting begins when 75% of the seeds are ripe and dried promptly after harvesting.This article provides references for the demonstration and promotion of high-yield seed production techniques for Quanxiangyou 89.
