以寒地水稻“三化”栽培技术为基础,将三膜覆盖技术、钵育苗技术、超稀植栽培技术、寒地优质米生产技术综合配套,组装了三膜钵育摆栽配套超高产栽培技术,并示范15亩。结果表明,增加积温70—105℃,减少昼夜温差,钵育壮苗,在同插期,育出4.1—4.5叶大苗。移栽规格30×16.7cm,每m220穴80苗,有效分蘖率与机插相比增加104%,以较少个体,建立高光效群体,亩产808.1kg,较机插增产42.1%。
Based on the cultivation technology of “three kinds of cultivation” of cold paddy rice, the three-membrane potting technology, potting and seedling technology, ultra-rare-earth cultivation technology and high-quality rice production technology in cold area were integrated. Technology, and demonstration of 15 acres. The results showed that increasing the accumulated temperature 70-105 ℃, reducing the temperature difference between day and night, Bowl Yu Zhuang Miao, in the same period, bred 4.1-4.5 leaf large seedlings. Transplanting specifications 30 × 16.7cm, 80 seedlings per m220, the effective tillering rate compared with the machine inserted increased by 104%, with fewer individuals, the establishment of high light efficiency population, 808.1kg per mu, more machine insert yield 42.1 %.
