根据杂交水稻的生理特性和四川盆地的生态特点,经过多年实践,提出地膜中苗、宽行双株、W调氮法、停滞期施氮相配套的稳促攻栽培新技术,使水稻生长前期群体动态结构稳定在最佳范围,培育健壮个体;中期(停滞期)扩源增库,增强物质运转,提高光合效能,促进产量构成因素协调发展,建造高产群体结构,后期改善群体受光态势,维持根系活力,延长功能叶光合时间,主攻穗重。该技术在生产上应用,一般较常规栽培增产12%左右。
According to the physiological characteristics of hybrid rice and the ecological characteristics of Sichuan Basin, after years of practice, put forward a new technology of stable seedling cultivation, The dynamic structure of the population was stabilized in the best range, and robust individuals were cultivated. In the mid-term (stagnant) expansion and expansion of repositories, the operation of materials was enhanced, the photosynthetic efficiency was enhanced, the coordinated development of yield components was promoted, the structure of high yield population was constructed, Root vitality, prolonged functional leaf photosynthetic time, the main attack ear weight. The technology is applied in production, generally about 12% more than conventional cultivation.
