Abstract: To provide technical support to two quarter tumorous stem mustard of the Fuling District of Chongqing Municipality, the split plot design was adopted to study the effects of different sowing dates, different varieties and seedling ways on growth period and yield of the second quarter of stem mustard. The results showed that, all of them had great impact on the growth period of the second quarter of the stem mustard. With the sowing date was postponed in our experiment, the vegetative stage and tumor stem growing stage were both shortened, the range were 3.5 days and 39.8 days, and the reduction were 2.2% and 41.5% respectively, while the calendar seedling age was growth, the range was 20.0 days, by increasing 60.6% . Compared with‘Yonganxiaoye’, the swelling beginning period of‘Fuza 7th’was moved forward 2.0 days in average, its tumor stem growing stage and vegetative stage was lengthened 6.3 days and 4.3 days respectively, and the squaring period was delayed 4.3 days. Those two seedling ways, by 7 cm diameter nutrition bowl and the 100-hole plastic plug, have the same growth period, while their vegetative stages were 2.0 days shorter than the regular seedling way in the same period, their tumor stem growing stage was 2.7 days longer, and the tumor stem swelling beginning period was moved forward 4.7 days. A1B2C1, which‘Fuza 7th’was sowed at the September 30th, by use of 7 cm diameter nutrition bowl, is the best treatment combination in this test , its yield could up to 72650.0 kg/hm².
