在红原县二龙场牧草试验基地开展了不同收获时间对"阿坝"硬秆仲彬草种子质量的影响试验。结果表明:随着收获时间的推迟,"阿坝"硬秆仲彬草种子含水量显著下降(P〈0.05),千粒重、发芽率、田间出苗率和加速老化后的发芽率在8月25日之前显著增加(P〈0.05),结实率在8月20日之前显著增加(P〈0.05)。综合种子质量的各项指标,结合红原地区的高寒气候条件,建议"阿坝"硬秆仲彬草种子在该地区及类似地区的收获时期不早于9月5日。
Experiments were conducted at Erlongchang experimental garden in Hongyuan City, with the order of testing the effects of different harvest time on Kengyilia rigidula cv.Aba seed quality. Results show that, as the harvesting time put off, the water content of Kengyilia rigidula cv.Aba seed declined significantly( P〈0.05); by August 25, the thousand seed weight, germination rage and emergence rate of the seed increased significantly(P0.05); and the mature rate of the seed, before August 20, increased significantly(P0.05). It was concluded that the harvesting time of Kengyilia rigidula cv.Aba seed should be control by October 5 in alpine region.
