通过对8个花生品种干物质生产的研究表明：高产花生品种有较高的生物学产量和经济系数。盛花后干物质的生产对花生经济产量的影响最大。盛花到成熟积累的干物质平均占总干物质的68.84%；经济系数平均达0.57。高产花生品种生育后半期有较高的干物质积累速率。

Through studied on eight peanut Cultivar’s production of dry materials,the result shoued: The high yield peanut cultivars had higher total yield and economic coefficient .It was biggest that the production of peanut dry material influence on the economic yield at after full bloom. The proportion of average of dry materials to the total dry material reached 68.84% from full bloom to ripe; The average of economic coefficient reached 0.57.The high yield peanut cultivars had higher accumulation rate of dry materials in after life.
