为全面普查和抢救性收集农作物种质资源,2011-2012年采用查阅文献、访问和实地调查相结合的方法,对分布在甘肃省干旱地区10个县/市的抗逆农作物种质资源进行了普查,填写基础信息表格960余张。通过资源普查发现,近25年来出现了气温升高、降雨量减少、农业总产值比重下降、小麦和特色杂粮杂豆锐减、生物多样性降低,抗旱形势严峻、资源保护压力加大等问题。针对这些问题,本研究提出了甘肃省农作物种质资源有效保护和高效利用建议,为科技创新和政府决策提供了基础信息和材料。
In order to conduct a comprehensive survey and rescue collection of crop germplasm resources, a comprehensive survey and rescue collection of crop germplasm resources were carried out in 2011-2012. By using the methods of literature review, interview and field survey, the germplasm resources of the resistant crop in 10 counties / cities in arid areas of Gansu Province were studied Census, fill in the basic information form more than 960 sheets. According to the census of resources, over the past 25 years, there have been some problems such as the temperature increase, the decrease of rainfall, the decrease of the proportion of total agricultural output value, the sharp decrease of wheat and other special grains and beans, the decrease of biodiversity, the severe drought situation and the pressure of resource protection. In response to these problems, this study proposed the effective protection and efficient utilization of crop germplasm resources in Gansu Province and provided basic information and materials for scientific and technological innovation and government decision-making.
