摘要
通过对怀川916小麦12 004.5 kg/hm2超高产产量构成因素的通径分析,探明各产量因素对产量影响的直接效应与间接效应,进而根据产量结构的数学模拟,揭示出3个产量因素相互影响此长彼消的变化规律,与此同时模拟得出不同产量水平的产量结构指标,并对其实现途径进行探讨,明确以力争穗数、确保穗粒数、稳定千粒重为夺取超高产的主攻目标。
Through path analysis of elements of super high yield 12 004.5 kg/hm2 of wheat Huaiehuan 916,this paper explored both the direct and indirect effeet of eaeh yield element on the yield,revealed the influences of the three yield elements and their changing rules according to the mathematical pattern of the yield structure.In the meantime,it modeled to get the yield structural index at different yield level and carried out an exploring discussion on the realization path, targeting at super high yield by getting more spike numbers, more particles and stable particle weight.
