在云南省涛源乡和福建省龙海市追踪观察了一批我国新近育成的水稻超高产品种。分析结果表明,①产量与单个构成因素一般无显著相关,与穗数、每穗粒数、粒重三者乘积——库容量呈极显著正相关。超高产水稻因品种类型不同表现出多样性的产量构成,但都具有库容量大的共同特点。②产量与收获指数无显著相关,与生物产量呈极显著正相关。超高产水稻的生物产量积累优势在中、后期,中、后期具有较高的群体生长率,是生物产量高的主要原因。说明库容量大和生物产量高是超高产的决定因素。 A series of super-high-yielding rice varieties newly bred in China were observed in Tao Yuan Township of Yunnan Province and Longhai City of Fujian Province. The results showed that: ① There was no significant correlation between yield and individual components, but significant positive correlation with the product-storage capacity of spikes, grains per spike and grain weight. Super-high-yielding rice has diversified yield components due to different types of cultivars, but all have the common characteristics of large storage capacity. ② There was no significant correlation between yield and harvest index, and significant positive correlation with biomass production. The bio-yield accumulation superiority of super-high-yielding rice has a high population growth rate in the middle, late, middle and late stages, which is the main reason for the high biomass yield. It shows that the large storage capacity and high biological yield are the determinants of super high yield.
