研究硼肥对热研11号黑籽雀稗（Paspalum atratum cv．Reyan11）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1124．4kg·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.
