摘要:
以生长2 a的扁穗冰草为试验材料，研究施肥期、收获期二因素对扁穗冰草种子产量、发芽率和千粒重的影响。结果表明：在盛花后25 d时收获种子，不同施肥期的扁穗冰草种子产量最高，盛花后30 d时收获种子，不同施肥期的扁穗冰草种子发芽率最高；返青期施肥，不同收获期种子扁穗冰草种子产量和发芽率均最高；施肥期、收获期二因素对扁穗冰草千粒重影响不大。
Abstract:
The experiment was conducted at Heilongjiang Academy of Agricultural Sciences.The experiment studied on the effects of fertilization period and harvest time on the amount of seed yield，germination rate and 1 000-grain weight of Agropyron cristatum which had been growing two years.The results showed that seed yield was the highest in different fertilization period when harvested seed after full bloom 25 days and germination rate was the highest when harvested seed after full bloom 30 days.When fertilization in period of seedling establishment，seed yield and germination rate were the highest in different harvest time.The different fertilization period and harvest time have little effect on seed 1 000-grain weight.
