摘 要:采用特异高产株型大豆沈豆4号进行了3年的研究,探讨了沈豆4号在不同年份、不同播种期条件下的生育规律。结果表明 ,沈豆4号的株高增长、单株生物产量积累和籽粒鼓粒过程均可以用Logistic曲线方程来描述。不同播期对沈豆4号植株形态和生育进程有很大影响 ,在5月10日前后播种最适宜 ,此时植株生物产量积累轨迹更合乎高速积累出现早、积累速率不偏高的高产积累轨迹。沈豆4号开花后期和植株上部形成的籽粒其灌浆速率最大。The dynamics of growth and development was studied using a soybean [Glycine max Merr.(L)] cultivar Shendou 4 with specific plant-type under different planting dates and different years. The results were as follows: The growth of plant height, the accumulation of biological yield and the filling of grain could be expressed by Logistic equation. The planting dates had strong effects on plant morphological traits, and growth and development of plants. The dynamics of biological yield of plants which planted on about May 10th matched the curve of high yield-the maximum accumulation stage appeared earlier and the accumulation rate not too high. The filling rates of grains which formed at the later stage of blooming and the upper placement of plant were the highest compared with those formed at other stages and placements.
