- 摘要:
- 通过技术引进和自主研发相结合，形成寒地水稻折衷直播高产新技术体系，其技术核心为早中熟耐寒品种、供氧剂种子包衣、机械旱直播、侧条施肥、早期灌水等5个技术要素。结果表明：选用龙粳8号，供氧剂包衣，播期在5月6~13日，播种量100.0～112.5 kg·hm-2，播深5～20 mm，产量可达到7 500 kg·hm-2以上。其生育表现：出苗数300～310株·m-2、有效穗数为550～600穗·m-2，穗粒数为58～62粒、总粒数33 000粒·m-2以上、成熟度82%～90%、千粒重24～25 g。
- Abstract:
- Combining technology transfer and independent，the new technology system of rice directly sowing was formed.Its core techniques were：early and mid-maturing varieties of resistant to cold，oxygen agent seed coating，mechanical dry seeding，fertilizer on the side，early irrigation，etc.The results showed that selecting Longjing No.8 varieties，applying oxygen coated，sowing date on the May 6th～13th，sowing 100.0～112.5 kg·hm-2at depth 5～20 mm，the yield could arrive at more than 7 500 kg·hm-2.Their beard performance：emergence number was 300～310 plant·m-2，panicles number were 550~600 spike·m-2，grain number per panicle was 58~62 grain，the total grain number was 33 thousand grain·m-2 or more，maturity 82%～90%，grain weight was 24～25 g.
