珂两优8612是籼型两系优质高产杂交水稻品种,2021年通过国家农作物品种审定委员会审定(国审稻20210283),该品种于2023—2024年示范种植,全生育期约136 d,分蘖力强,抗倒伏;平均产量600~650 kg/667 m2。本文总结了珂两优8612的工厂化育秧及栽培技术要点,育秧环节包括浸种消毒、高温催芽,使用pH 5.8~6.2的专用基质,叠盘暗化促齐苗;秧田分阶段控温控湿,2叶1心期喷施多效唑并追肥,秧龄18~24 d时移栽。大田管理方面,深耕整平,合理密植;水分管理遵循“浅水活棵、够苗晒田、湿润灌溉”原则;分蘖期追肥促蘖,及时烤田,拔节期依苗情补肥壮秆,穗期分2次施用穗肥;全生育期依据病虫监测,重点防治稻飞虱、纹枯病等病虫害;通过晒田、增钾、调节播期及灌深水、喷施叶面肥等措施,防御倒伏、高温及低温冷害。收获与储存方面,适时机械收获,稻谷烘干至水分14%以下后于通风防潮仓库储存。本文为珂两优8612的进一步推广种植提供参考。

Keliangyou 8612 is a high quality and high yield hybrid rice variety of indica type with two lines. It was approved by the National Crop Variety Approval Committee in 2021 (National Approved Rice 20210283). This variety demonstrated for planting in 2023-2024, with a total growth period of about 136 days, strong tillering ability, and lodging resistance; the average yield was 600-650 kg/667 m2. This article summarized the key points of factory based seedling and cultivation techniques for Keliangyou 8612. The seedling cultivation process includes soaking and disinfecting the seeds, high-temperature germination, using specialized substrates with pH 5.8-6.2, and stacking and darkening to promote uniform seedling growth; the paddy field is controlled by temperature and humidity in stages, with spraying of paclobutrazol and topdressing at the stage of 2 leaves and 1 heart. The seedlings are transplanted at 18-24 days of age. In terms of field management, deep plowing and leveling, reasonable and dense planting; water management follows the principle of “shallow water for living trees, sufficient seedlings for sun drying, and moist irrigation”; apply fertilizer to promote tillering during the tillering stage, bake the field in a timely manner, supplement plump stems according to the seedling situation during the jointing stage, and apply ear fertilizer twice during the panicle stage; based on disease and pest monitoring throughout the entire growth period, focus on preventing and controlling diseases and pests such as rice planthoppers and sheath blight; by measures such as sun drying, increasing potassium, adjusting sowing time, irrigating deep water, and spraying foliar fertilizer, we can defend against lodging, high temperature, and low temperature damage. In terms of harvesting and storage, timely mechanical harvesting is carried out, and the rice is dried to a moisture content of less than 14% before being stored in a ventilated and moisture-proof warehouse. This article provides reference for further promotion and planting of Keliangyou 8612.
