摘　　要：在湖北鄂州和武汉进行了芝麻新品种中芝12的播期、密度、打顶、化控及高产攻关试验,结果表明,该品种的最适宜播期为5月30日,密度为每公顷15万株,第3对真叶期间隔1周连喷两次150mg.kg-1或200mg.kg-1缩节胺。中芝12在高肥水条件下不宜打顶,但在一般种植条件下以初花后25d打顶效果好。鄂州和武汉高产攻关公顷产量分别为2139.75kg和2418.75kg。The trials of sowing date, plant density, tip cutting, chemical control and high yield for sesame cuhivar Zhong-zhi 12 were conducted in Ezhou and Wuhan of Hubei Province. The results showed that for Zhong-zhi 12 the suitable sowing date was May 30 and the suitable density was 15×10^4 plantshm^-2. DPC （N,N-dimthy piperidinium chloride） solutions sprayed at stage of three pairs of leaves with one week interval in 150mg·kg^-1 or 200mg·kg^-1 two times were fitted for yield increase. It seemed that Zhong-zhi 12 was not suitable for tip cutting in high fertilizer condition and could be done 25 days after initial flowering in average condition. The seed yields of Zhong-zhi 12 in high yield trials were 2 139.75 kg·hm^-2 and 2 418.75 kg·hm^-2 in Ezhou and Wuhan, respectively.
