摘　　要：通过湘北平湖区湘晚籼17号晚稻抛栽高产配套技术研究与推广,结果表明:(1)适宜用种量60～75 kg/hm2;(2)适宜大田施氮量187.5～202.5 kg/hm2;(3)秧田用多效唑1 200～1 500 g/hm2喷施1～2次,可矮化秧苗和提高秧龄弹性;(4)抛栽后二周左右用5%稻杰600～900 mL/hm2加10%千金乳油600 mL/hm2,防除杂草效果好;(5)大田推广高产栽培技术,种植33.4 hm2,群体结构合理,产量高,平均产量7.20 t/hm2,高产丘块8.18 t/hm2。基本解决了除草、优质高产、倒伏等问题,提高了农民种粮经济效益。The research and popularization of seedling-throwing culture and supporting techniques for high-yield of Xiangwanxian No.17 were conducted in Pinghu District of Northern Hunan.The results indicated that the optimum seedling amount was 60-75 kg/hm^2;the optimum nitrogen application rate was 187.5-202.5 kg/hm^2;the treatment that spraying PP333 with dosage of 1 200-1 500 g/hm^2 to seedling field once or twice could dwarf seedlings and enhance elasticity of seedling age;the treatment that applying 5% of Penoxsulam with dosage of 600-900 mL/hm^2 plus 10% of cyhalofop-butyl emulsifiable solution with dosage of 600 ml/hm^2 to field two weeks after seedling-throwing had the best weed control effect.Applying high-yield culture techniques to 33.4 hm^2 of field will has rational group structure and high yield,the average yield was 7.20 t/hm^2 and the high-yield block reached 8.18 t/hm^2.The Xiangwanxian No.17 basically solve all the problems of weed and lodge and has great characters of high quality and high-yield,it increase the economic benefits of rice planting for farmers.
