| 摘 要： | 通过不同施肥用量对百喜草种子产量和质量的影响研究,结果表明:每公顷施用N75kg、P2O552.5 kg和K2O52.5kg可显著提高百喜草种子产量,而且有利于土壤培肥;同时增施叶面肥可以相应增加百喜草种子结实率和千粒重,有利于提高百喜草种子的质量。施肥量过高或偏施氮肥,导致百喜草营养生长过旺,达不到理想的有效穗数,反而不利于实现百喜草种子高产。

| Abstract: | The experiments were conducted to study the effects of fertilizer application rate on seed yield and quality of Bahia grass(Paspalum natatum Flugge).The result showed that applying N 75kg,P2O5 52.5kg and K2O 52.5kg per hectare could remarkably increase Bahia grasses seed yield and improve the soil fertility;spraying fertilizer solution on leaves of Bahia grass could increase the seed setting percentage and the 1000-grain weight,thus improve the quality of Bahia grass seeds.Excessive fertilizer application or being partial to nitrogen fertilizer would make Bahia grass vegetative growth too prosperous,and could not get the perfect numbers of productive ear,which would not get high yield of Bahia grass seeds. |
