摘要： 对不同施肥水平下旱地花生荚果发育动态的研究结果表明：旱地花生荚果重量和体积增长过程呈“慢—快—慢”变化，可拟合成Logistic方程，荚果重量最大增长日为幼果形成后43~48d，最大增长速率为0.3791~0.5947g／株·d；荚果体积最大增长日为幼果形成后36~39d，最大增长速率为0.8487~1.6684cm3/株·d。荚果重量和体积快速增长期持续20~30d。随施肥量的增加，荚果重量和体积最大增长日出现时间推迟。

Abstract: The study focused on pod development of dryland peanut by different treatments of fertilizer application.The results showed that pod weight and pod volume increasing could be characterized as a “slow-rapid-slow”rhythm.It’s cumulative dynamics was simulated by a Logistic eguation.The growth rate of pod weight had a peak of 0.3791~0.5947g/plant·d at 43~48day after emergence,and the peak(0.8487~1.6684cm3/plant·d)of growth rate of pod volume occurred at 36~39day after emergence, the rapid growth period was 20~30days.Date of peak growth rate of pod weight and pod volume had a changing process from earlier to later with an increase of the amount of fertilizer application.
