本研究以福州市龙江、鼓一大队稻麦三熟高产田为基础,结合栽培试验高产田调查,着重探索水稻高产生物学动态指标。其目的在于揭示水稻高产形成的内在原因及其与外部联系的规律,为早稻亩产1000～1100斤、晚稻亩产1300斤的技术工程方案提供合理的调控实施。一、产量构成因素及产量指标:稻谷产量=穗数×每穗粒数×结实率×粒重。红410比广陆矮等矮杆品种增产,主要在于穗多、粒大。四优2号比多数杂优组合增产,
Based on the high-yielding rice and wheat field of Longjiang and Fuzhou, and the high-yielding cultivation of rice and wheat, this study focused on the biological indicators of high yielding rice. The purpose is to reveal the inherent causes of rice high yield formation and its relationship with the external rules for the early rice per mu yield of 1000 to 1100 pounds, late rice yield of 1,300 pounds of technical engineering programs to provide a reasonable regulation and implementation. First, the yield components and yield indicators: rice yield = spike × grains per spike × seed rate × grain weight. Red 410 shorter than the Canton land short bar varieties increase production, mainly in the spike, grain. Siyou 2 than the majority of hybrid combinations yield,
