引言在澳大利亚北部天然草原的烧荒地区,当下层土水分充足时,通过撒播和施肥能够改良草原。草地上有了Verano柱花草,改进了草地的质量和稳定性。播种前的重牧而后适度放牧有助于Verano柱花草的定植。但是,种子发芽率低仍然是降低有效定植的主要问题。如果提供的Verano柱花草种子是在最适宜发芽和定植的时间播种,那么将获得最好的结果。但是,硬实种子的含量通常大于90％,它们软化之后才能发芽。Mott等人 INTRODUCTION Grasslands can be improved by sowing and fertilizing when the underlying soil is abundant in the burned areas of native grasslands in northern Australia. With Verano stalks on the grass, it improves the quality and stability of the grass. Heavy grazing before sowing and then grazing moderately helps Verano colonization. However, the low germination rate of seeds is still a major issue in reducing effective colonization. The best results are obtained if the Verano Colza seeds are provided at the most suitable time for germination and colonization. However, the content of hard seeds is usually greater than 90% and they soften before they germinate. Mott et al
