以水稻新品种武陵粳1号为材料,以粮食丰产工程项目的实施为依托,对其高产群体产量及其结构、群体茎蘖动态、群体叶面积指数动态、群体干物质积累动态进行了研究,提出了武陵粳1号高产群体定量化指标,同时总结出了配套的精确栽培技术,并绘制成栽培规程图,为武陵粳1号大面积高产提供技术支持。 Taking the new rice variety Wulingjing 1 as the material and based on the implementation of the grain yielding project, the dynamics of yield and its structure, stem and tiller dynamics, population leaf area index and dry matter accumulation dynamics of the population were studied. The quantitative index of high yielding population of Wulingjing 1 was put forward. At the same time, the precise planting techniques were summarized and drawn into the cultivation procedure chart to provide technical support for large area and high yield of Wulingjing 1.
