随着全球气温普遍的升高,高寒地区的季节长短会发生一定的变化,这对植物生长尤其是农作物栽培有着重大影响。一方面由于气温升高可栽培的农作物种类增多、生长成熟期缩短、作物生长发育速度加快、植株增高增粗等;另一方面农作物有可能适应不了环境变化的速度,导致农作物减产或无法生存,而且高温天气容易导致病虫害的增加、当地生态系统的破坏等。故高寒地区农作物栽培随着气候变化下的反应过程及应对措施成为国内外科学家所关注的问题。
With the general increase of global temperature, seasonal changes in the alpine region will have some changes, which have a significant impact on plant growth, especially crop cultivation. On the one hand, due to the increase of temperature, more varieties of crops can be cultivated, the growth and maturity of the crop is shortened, the growth and development of crops are accelerated, and the plants are thicker and thicker. On the other hand, crops may not adapt to the speed of environmental change, And hot weather easily lead to increased pests and diseases, the destruction of the local ecosystem. Therefore, crop cultivation in the alpine region with the climate change under the reaction process and response measures have become the concern of scientists at home and abroad.
