选用各地不同基因型小麦品种,经三年连续试验,初步揭示出不同品种在灌浆期的共同规律:籽粒干物质累积按慢—快—慢顺序,呈“s”形分布;不同品种各有灌浆高峰期。此期内营养物质流进入籽粒是符合y=ab~x方程。对于影响灌浆的多种外界因素,经过多元逐步回归分析,提出了影响粒重的主要因素最优方程。研究了灌浆期源、库、流关系,并探明若干具有优良灌浆性状的品种。
Selection of different genotypes of wheat varieties throughout the three years of continuous testing, initially revealed the common law of different varieties in the filling stage: dry matter accumulation in the slow-fast - slow sequence of grain growth, was “s” shaped distribution; different varieties have grouts Peak period. Nutrient flow into the grain during this period is in line with y = ab ~ x equation. For multiple external factors affecting grouting, after multiple stepwise regression analysis, the optimal equation of the main factors influencing grain weight was proposed. The relationship between source, reservoir and flow during filling period was studied, and several varieties with excellent grain filling characteristics were identified.
