摘要
在田间试验条件下,以普通型花生品种8130为材料,系统研究了花生荚果、籽仁和果壳干物质积累规律。结果表明,花生进入结荚期,荚果干质量和籽仁干质量的增加均经历渐增期、快增期、缓增期三个时期,其增加规律可用生长曲线logistic方程进行模拟;荚果干质量和籽仁干质量在荚果形成后70~80d仍有明显增加,80d以后增加不明显;从荚果形成后20d至收获期荚果出仁率的提高可用多项式进行曲线模拟,荚果出仁率在荚果形成后80d左右达到最大值。研究认为,威海地区9月底为普通型大花生的适宜收获时期。
The dry matter accumulation characteristics of peanut pod,kernel and shells were studied in the field experiment with ordinary peanut variety 8130 as material.The results indicated that,in the stage of peanut pod formation,the dry mass increasing of pod and kernel include three stages,such as gradual increase,fast increase and slow increase,which can be simulated by the Logistic equation of growth curve.The dry mass of pod and kernel increased significantly from 70 to 80 days after pod formation,but not increased after 80 days.The increasing of the kernel yield from 20 days to harvest period can be simulated by polynomial.The kernel rate reached the maximum value at the 80th day after pods formation.The study concluded that the suitable harvest period of the common large peanut in Weihai district is in late September.
