伴随能源价格的上涨,美国的花卉种植者都在寻找方法以降低能源成本并提高现有温室空间利用效率。通过对三色堇、报春花等主流低温作物的研究,研究者发现,很多从夏季一年生花卉中选育出的品种在低温条件下同样能够良好地生长。种植者通过制定正确的栽培计划并注意一些重要的栽培管理细节,以上花卉品种的品质有很多甚至优于在较高温度下种植出来的产品。 Accompanied by rising energy prices, flower growers in the United States are looking for ways to reduce energy costs and improve the efficiency of space utilization in existing greenhouses. By studying mainstream low temperature crops such as Pansy, Primrose, the researchers found that many of the varieties bred from summer annual flowers also grew well at low temperatures. By cultivating the correct plan of cultivation and noting some important details of cultivation and management, growers have many or even better qualities than those planted at higher temperatures.
