本文介绍了杂交水稻品种喜两优晶丝占的亲本来源及选育过程、特征特性,总结了其高产栽培及制种技术。该品种是以喜06S为母本,喜晶丝占为父本育成的优质杂交水稻品种,适宜在长江中下游地区作一季中稻种植,具有田间长势优良、品质优、中抗稻瘟病和产量高等特性。其高产栽培技术包括适时播种,播种前采取药剂浸种处理;秧龄25 d左右移栽,确保基本苗数在90万~110万株/hm2;施足基肥、早施分蘖肥,后期根据植株长势补施磷、钾肥;移栽后7 d,采取丁草胺等药剂防治田间杂草;施用43%戊唑醇等药剂防治稻曲病、纹枯病、稻飞虱等病虫害。高产制种技术包括选择光照充足、肥力中上、排灌便利的地块制种,注意制种隔离;合理安排父母本播差期;播种前撒施有机肥并深耕,播种后保持田面湿润,适时追肥;适时喷施赤霉素“九二〇”,父、母本抽穗达到50%时安排人工赶粉;根据田间实际情况进行去杂,及时防治田间病虫害;种子85%左右成熟时采取专用收割机收获。本文为该品种在相关地区推广种植提供参考。

The parental sources, breeding process, and characteristics of hybrid rice variety Xiliangyoujingsizhan were introduced, and its high yield cultivation and seed production techniques were summarized. This variety is a high quality hybrid rice variety developed from Xi06S as the female parent and Xijingsizhan as the male parent. It is suitable for planting as mid season rice in the middle and lower reaches of the Yangtze River and has excellent field growth, high quality, moderate resistance to rice blast disease, and high yield. The high yield cultivation techniques include timely sowing and soaking with pesticides before sowing; transplant seedlings at around 25 days of age to ensure a basic number of 900 000 to 110 000 plants/hm2; apply sufficient basal fertilizer, apply tillering fertilizer early, and supplement phosphorus and potassium fertilizers according to plant growth in the later stage; after 7 days of transplantation, use pesticides such as butachlor to control weeds in the field; apply 43% tebuconazole and other pesticides to prevent and control diseases and pests such as rice blast disease, sheath blight, and rice planthoppers. High yield seed production techniques include selecting plots with sufficient light, medium to high fertility, and convenient drainage and irrigation for seed production, and paying attention to seed isolation; reasonably arrange the parents’ broadcasting schedule; apply organic fertilizer and deeply plow before sowing, keep the field moist after sowing, and apply fertilizer at appropriate times; timely spray gibberellin “920”, and arrange manual powder milling when the heading rate of the parent plants reaches 50%; according to the actual situation in the field, remove impurities and timely prevent and control diseases and pests in the field; harvesting with a specialized harvester at around 85% maturity of the seeds. This article provides a reference for promoting and planting this variety in relevant regions.
