摘要
研究硼肥对热研11号黑籽雀稗(Paspalum atratumcv.Reyan 11)种子产量和品质的影响。试验设9个硼肥处理,质量分数范围为0～4.0%,分3次施入。结果表明,施硼量3.0%(3%的硼酸分3次施入:400mL+400mL+600mL)的效果最好,种子产量达1 124.4kg.hm-2。施硼肥可提高生殖枝数、小花数/小穗、可育小花数/小穗和种子千粒重,但对小穗数/生殖枝影响不显著;施硼肥能提高种子的发芽率、发芽势、发芽指数以及芽长和芽质量。施硼量3.0%可以使发芽率达到20.17%,比对照提高了30%。
Effects of boric fertilizer application on seed yield and germination of Paspalum atratum cv. Rey- an 11 were studied by a pot experiment in this study. The experiment included 9 different boric concentra- tion treatments （0-4.0%）. Each treatment was divided into 3 applications. The results showed that seed yield reached the highest of i 124.4 kg·ha^-1 with 3.0% boric treatment. 3.0% boric treatment signifi- cantly raised seed yield components, including fertile tiller nubmer per pot, floret number per spikelet, fertile floret number per spikelet and thousand grain weight . The fertilizer also raised seed germination rate, germination potential, germination index, seedling height and weight. Seed germination rate under 3.0% boric treatment reached to 20.17% and 30% increase compared with control.
