Online published: 2026-02-09
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.
