种子产量是种子生产的首要问题,迄今为止,提高牧草种子产量的研究一直是国际种子科学研究的热点,通过对播种期、施肥量、施肥时间的研究,选择投入低、产出高的田间管理技术,可以使生产效益得到大幅度提高。禾本科牧草种子产量的直接影响因 Seed yield is the primary problem of seed production. Up to now, the research on improving the seed yield of forage grass has been the hotspot of international seed science research. Through the study of sowing date, fertilizer application rate and fertilization time, field management with low input and high output Technology, can make a substantial increase in production efficiency. The direct impact of gramineous forage seed yield
