[Method] Double factor randomized block design （2 fertilization methods and 5 ratios） was adopted, with 10 treatments, 3 repeats. There were a total of 30 plots, with plot area of 12.0 m2. Two fertilization methods included C1 [base fertilizer （540 g/plot compound fertilizer ＋ topdressing （90 g urea）] and C2 [all as base fertilizer （540 g/plot compound fertilizer）]. Five different proportions （sesame： peanut） were M1（2∶4）, M2（2∶6）, M3（1∶4）, monoculture sesame （CK1） and monoculture peanut （CK2）, respectively. [Result] Output value and land equivalent ratio （LER） of C1M2 treatment （6 lines peanut/2 lines sesame, base fertilizer 540 g/plot （compound fertilizer） ＋ （topdressing urea 90 g） were the highest of 22 378.68 yuan/hm2 and 1.56 respectively; sesame yield was 641.64 kg/hm2 and peanut yield was 2 506.67 kg/hm2. Output-input ratio was 4.94. The income was increased by 32.32% and 95.97% compared with only planting of peanuts and sesame. [Conclusion] The study provided a theoretical basis for finding the best intercropping combinations of sesame and peanut and rational application fertilizations.展开更多

[Method] The number of flowers and capsules at lower part （below the 8th node from the bottom）, middle part （at 9th-20th nodes from the bottom） and upper part （above the 20th node） of sesame plants （Zhengzhi 98N09） was counted. The length, width, fresh weight of the capsules, fresh and dry weight of the seeds, and the dry weight of the capsule shel s at dif-ferent growth stages were measured. [Result] From the bottom to the top of sesame plants, the numbers of flowers and capsules at each node showed a trend of first increasing and then decreasing. The 15th and the 12th node had the maxi-mum flower number （9.3 flowers per node on average） and the maximum capsule number （4.2 capsules per node on average）, respectively. The middle nodes had the highest capsule setting rate, up to 45.1%, fol owed by that at upper nodes, 30.1%, and the capsule setting rate at lower nodes was the smal est, only 25.0%. The capsule length, width, fresh weight, seed fresh weight, dry weight and capsule shel dry weight at middle part were higher than that at lower and upper part. Moreover, grain fil ing rates of the lower, middle and upper capsules were 0.003 5, 0.004 4 and 0.003 0 g/（capsule·d）. It suggests that the substances gave priority to supply the middle capsules during the development of capsules. [Conclusion] This study wil provide theoretical basis for the cultivation of high-yielding sesame.展开更多
