China News Service, Lanzhou, March 14 (Ai Qinglong) Jiang Chengying, director of the Olive Engineering Technology Research Center of the Gansu Forestry Research Institute, said that at present, the area of the olive industry in Longnan, Gansu has developed to 759,600 mu, accounting for about half of the country's total area. It accounts for more than 70% of the country and is the largest olive production base in China.
However, in terms of varieties, there is a lack of "master varieties" with high yield, high oil content and strong resistance that adapt to local ecological conditions.
Olive oil is a well-known subtropical fruit tree and an important economic forest, mainly concentrated in the countries along the Mediterranean Sea.
Olive oil made from olive oil has the functions of preventing cardiovascular and cerebrovascular diseases and anti-tumor. It has a wide range of uses in medicine, daily necessities, chemistry, electronic food, textiles and other industries.

"Although there are as many as 143 olive varieties introduced in Gansu, they are still in the stage of simple introduction." Jiang Chengying analyzed to a reporter from Chinanews.com on the 14th that the subtropical regions of northwestern China have abundant resources and secure land, which are important for the "settlement" of olives in Longnan. reason.
But at the same time, it is also faced with restrictive factors such as "low winter temperature in the west and low temperature freezing damage".
This is also the biggest difference from other planting areas, and simple introduction cannot achieve optimal results.
Therefore, it is unquestionable to cultivate varieties that meet China's climate and soil conditions.
Olive oil was introduced on a large scale from Albania decades ago. It was initially cultivated in 15 provinces in China, and only three production areas remained in Gansu, Yunnan and Sichuan.
Half a century later, as the "lucky one", Longnan's products won the gold medal at the "New York International Olive Oil Competition", the China Olive Industry Innovation Strategic Alliance was also established locally, and even Longnan's olive seeds are still being carried in space for testing, aiming to Selecting better quality olive seeds from "Space Seeds" for planting, so as to expand the area of olive trees and improve the yield and quality.
Jiang Chengying said that by the end of 2021, the area of the olive industry in Longnan has grown to 759,600 mu, and its products have appeared in many cities in the form of franchise stores, and have also been exported to South Korea.
At present, Longnan is the region with the richest collection of olive germplasm resources in China. In view of this, the olive base of Gansu Academy of Forestry has been identified as the national olive tree germplasm resource bank.
When Jiang Chengying reviewed the achievements of olive oil, he was mixed.
She said that in recent years, the government has cultivated 17 olive processing enterprises, built 28 virgin oil production lines, and won more than 60 international and domestic awards.
However, it is still necessary to clearly understand that the process of "localization" of olive oil is slow.
Jiang Chengying has always been committed to the "localization" of olive oil, and has set up a test base in Lanzhou, where a total of about 20,000 seeds of 24 combinations of artificial hybridization have been sown to breed new varieties.
Jiang Chengying believes that olive oil likes light, is drought tolerant, and is afraid of low temperature, and cultivating resistant varieties and innovative cultivation models is the only way to expand the planting area and scale.
It is reported that the relevant content of the improvement of olive germplasm has been written into the draft of the key special guideline for the “Cultivation and Quality Improvement of Forest Germplasm Resources”, the key research and development plan of the national “14th Five-Year Plan”.
At the same time, in order to ensure the "quality and quantity" of the olive industry, Longnan officials have formulated a plan to build a ten billion olive industry cluster in 2022.
Jiang Chengying believes that this plan is conducive to boosting the research and development of varieties and realizing the sustainable development of the olive industry.
In this regard, she suggested that the state will incorporate its planning into the national advantageous and characteristic industrial cluster construction plan, and provide support in the construction of standardized production bases and supporting infrastructure, product intensive processing, scientific and technological support service system, brand and marketing system, and industrial management organization system construction. policy and financial support.
