我国农作物的栽培受到地域、气候、环境的多种因素影响,产生了一地域栽种多种作物的现象,以甘肃农作物栽植情况为例,甘肃地域狭长,维度跨越比较大,气候环境比较多样化,其主要栽种的农作物是小麦、玉米、马铃薯、胡麻、油菜、药材、蔬菜和瓜果等几大类,春农作物主要分布于陇西和河西地区,冬农作物主要分布于陇东和陇南地区。制约甘肃主产区农作物生长的自然条件是夏季干旱、炎热、缺水,冬季寒冷等因素,为了缓解北方水资源匮乏等自然状况,我国做出了许多应对举措,如南水北调工程已经初见成效,但从根本源头解决农作物抗旱问题需要有新的栽培方式。本文针对甘肃地区的农作物抗旱育种进展与方式进行分析与探讨。
The cultivation of crops in our country is influenced by many factors such as region, climate and environment, resulting in the phenomenon of planting a variety of crops in a region. Taking the cultivation of crops in Gansu Province as an example, the region of Gansu is long and narrow with more dimensions and diverse climates. The main crops are wheat, corn, potato, flax, rape, herbs, vegetables and fruits. Spring crops are mainly distributed in Longxi and Hexi areas. Winter crops are mainly distributed in Longdong and Longnan. The natural conditions that restrict the growth of crops in the main producing areas of Gansu Province are the factors of drought, heat, water shortage and cold winter in summer. To alleviate the natural conditions such as the scarcity of water resources in northern China, many measures have been taken. For example, However, it is necessary to find new cultivation methods to solve the problem of drought resistance of crops at the fundamental source. This paper analyzes and discusses the progress and ways of crop drought resistance breeding in Gansu.
