研究了１５、２５和３５℃三种温度下四棱豆的发芽特性以及三播期下的生育特性．结果表明，随着温度的升高，正常发芽率提高，非正常发芽率和霉烂率下降，且以浸种为优．不管早播还是迟播，初花期均在９月初；花荚脱落的高峰期在开花后的２～５天，总脱落率为７０％以上． The germination characteristics of Amorphophallus nigra under 15, 25 and 35 ℃ were studied, and the fertility characteristics under the three sowing date were studied. The results showed that with the increase of temperature, the normal germination rate increased, the abnormal germination rate and rotten rate decreased, and the soaking was better. Regardless of the early sowing or late sowing, the early flowering are in early September; flower pods shedding peak 2 to 5 days after flowering, the total shedding rate of more than 70%.
