利用河南省粳稻区域试验、生产示范及国家北方中晚粳区域试验资料 ,对GS豫粳 6号的丰产性、稳产性和产量结构进行了分析。结果表明 :GS豫粳 6号在产量构成三要素中 ,有效穗数对产量的直接作用最大 ,千粒重次之 ,穗粒数的直接作用最小。因此 ,在高产栽培上 ,应主攻亩成穗数 ,同时兼顾穗粒数 ( 1 0 0粒左右 )和千粒重 ( 2 6g左右 )。 Based on the regional trials of Henan japonica rice, demonstration of production and the experimental data of middle and late japonica rice in the northern part of China, the fertility, yield stability and yield structure of GS Yujing 6 were analyzed. The results showed that among the three elements in the yield components, the effect of the effective panicle number on the grain yield of GS Yujing 6 was the largest, followed by the grain weight of 1000 and the direct effect of grain number per panicle was the smallest. Therefore, in high-yielding cultivation, should be the main number of acres of spike, taking into account the number of grains per acre (about 100) and 1000 grain weight (about 26g).
