China News Service, Lanzhou, November 9th (Ai Qinglong) Guo Tianwen, a researcher at the Gansu Academy of Agricultural Sciences, said in an interview with reporters on the 9th that in recent years, the traditional agricultural province of Gansu has started with agricultural "chip" seeds, successively from the United States, Japan, and Japan. France, Spain and other countries have introduced tens of thousands of germplasm resources of grains, cotton, fruits, vegetables, etc., and used these germplasm resources to cultivate high-yield, high-quality, disease-resistant new varieties and germplasm materials.

　　Gansu, located in the inland northwest of China, is one of China's important crop species domestication areas. It is also a resource-type water-scarce province. It directly quotes foreign varieties, showing low yields and non-resistance to local pests and diseases.

Therefore, "Yuxin" is very important.

　　Guo Tianwen said that after Gansu introduced wheat, corn and other foreign varieties resources from the United States, Australia, Italy and other countries, it screened out a number of breeding materials such as resistance to stripe rust and high protein. Through digestion, absorption and independent innovation, they bred Longchun and Orchid. Tian, ​​Longjian and other series of varieties.

　　Lu Qinglin, a researcher at the Wheat Research Institute of Gansu Academy of Agricultural Sciences, once cited the wheat variety "Lantian 36" as an example. "Lantian 36" created a demonstration field with high yield and high efficiency in Hui County, Longnan City, Gansu, creating an average yield of 620.88 kg per mu. score.

This variety can block the airflow transmission channel of stripe rust from the source, and has a major effect on reducing the damage of stripe rust to wheat areas.

　　Not only that, the germplasm resources of malting barley imported from Hungary in Gansu have successively cultivated new varieties of favavit and sweet beer series, which have become the main varieties of Gansu, Inner Mongolia, Ningxia, Qinghai, Xinjiang and other provinces of the northwest wheat region.

According to the "2021 Gansu Agricultural Science and Technology Green Paper", these varieties accounted for more than 95% of Gansu's beer barley planting area and more than 40% of Xinjiang's beer barley planting area.

　　In addition, the "Introduction and Breeding of New" new potato varieties, such as Longshu No. 7 and LK99, have been promoted in an area of ​​over 2.1 million hectares, with an additional net income of more than 8 billion yuan.

　　Today, Gansu has established international scientific and technological cooperation such as "China-Dutch Technology Transfer Center for Industrial Contaminated Soil Management in Arid and Semi-arid Areas", "Water-saving and High-efficiency Agriculture in Arid Irrigation Areas", and "Wheat Stripe Rust Gene Control" National Intelligence Introduction Demonstration Base. platform.

　　In this regard, Guo Tianwen said frankly that although the number of international cooperation in Gansu agriculture is insufficient and special funds are lacking, there are gratifying results.

In the next step, relying on the advantages of selection and breeding technology, new crop varieties such as Longshu series and sweet beer series and agricultural technologies such as dry farming and saline-alkali soil improvement will be targeted and step-by-step to carry out products and technologies in countries along the "Silk Road".
