通过定期挖株调查,对豫芝11号夏播芝麻生长动态进行了研究。研究结果表明,夏播芝麻光合产物积累速度以播后47～62d最快,平均每公顷每天为103.13kg。主根长度及支根数量在62d以前增加较快,62d以后趋于稳定,但重量不断增加。茎秆增长高峰、叶面积系数最大值均出现在播后47～62d,62d后增长缓慢。77d以后45%以上光合产物都分配于生殖生长上,单株粒重、千粒重也迅速增加。千粒重、蒴果重均与芝麻产量密切相关。收获时经济系数为27.54%。
Through the regular dredging survey, the seeding growth of Yuzhi No.11 summer sesame was studied. The results showed that the summer sowing sesame photosynthetic product accumulation rate after sowing 47 ~ 62d the fastest, an average of 103.13kg per hectare per day. The main root length and root number increased rapidly before 62d, after 62d tends to be stable, but the weight continues to increase. The culm growth peak and the maximum leaf area coefficient all appeared at 47-62 days after sowing, and then increased slowly after 62 days. More than 45% photosynthetic products were distributed on reproductive growth after 77 days. Grain weight per plant and thousand kernel weight also increased rapidly. Thousand grain weight, capsule weight and sesame production are closely related. The economic coefficient at harvest was 27.54%.
