摘要
以黑龙江省主栽的两个水稻品种为试验材料,通过调查试验材料的生育期、干物质积累、叶面积变化和分蘖消长动态的测定,明确了拔节至抽穗期是水稻产量形成的关键时期;根据试验材料干物质积累的变化规律建立了干物质随时间变化的生长曲线,经检验拟合较好。
Taking two rice varieties mainly planted in Heilongjiang Province as entries, through the investigation of growth period, dry mater accumulation, leaf area change and filler development, it was certified that jointing stage to heading stage is the crucial period determining yield formation. The growth curve of dry matter accumulation was built and the test of goodness of fit was good.
