通过研究尖叶胡枝子和达乌里胡枝子种子形成特性及生产性能,结果表明,尖叶胡枝子和达乌里胡枝子从返青期到种子形成分别需要111~121 d和103~108 d;二者生殖枝率较高,可达95%,尖叶胡枝子的单株花序为805.6个,达乌里胡枝子为277.0个;二者日开花高峰时间不同,尖叶胡枝子出现在9∶00~10∶00,达乌里胡枝子在10∶30~11∶30,而二者闭花高峰均出现在15∶30~16∶00;尖叶胡枝子的结荚率和成熟率比达乌里胡枝子高,种子收获期不同,种子的发芽率、硬实率和千粒重也不相同,两种胡枝子适宜的收获期均在9月20日左右,种子贮藏时间对其发芽率和硬实率有明显的影响;尖叶胡枝子的种子产量为607.33 kg/hm2,达乌里胡枝子为591.77 kg/hm2。
Through the study of the formation characteristics and performance of Lespedeza dorsalis and Lespedeza dahurica seeds, the results showed that the needles of Phalaris arundinacea and Dalu harness were 111 ~ 121 d and 103 ~ 108 d respectively from the stage of greening to seed formation. The rate of reproductive shoots was higher, reaching 95%. There were 805.6 inflorescences of Lespedeza tenuis and 277.0 Lespedeza dulcis. The peak flowering time of the two plants was different, 00 ~ 10:00, dahurica branches in 10:30 ~ 11:30, and the two flowers are peaked at 15:30 ~ 16:00; Lespedeza venezuela pod and maturity ratio than The growth rate of the seedlings was different from that of the seedlings. The seed germination rate, the rate of hardwood seed and the grain weight of one seedling were also different. The suitable harvest period of both species was about September 20, The yield of Lespedeza notoginseng seeds was 607.33 kg / hm2, and that of Lespedeza dahurica was 591.77 kg / hm2.
