Dingxi: Pentofu

Dingxi City, Gansu Province is a must -have place where the ancient Silk Road town and the New Eurasian mainland bridge must pass. In 1925, the newly reckless weighing of Dingkou Town, Dingxi City, reflects the prosperity of the city's once business travel. Today, the people here use hard -working hands to create two major business cards of "potato breeding" and "authentic medicinal materials". The hot soil of Dingxi is no longer bitter and no longer, and Panfu is expected.

"Provide a potato seed for all Chinese people every year"

The Chinese character "species" means "planting the next acre field" for Dingxi, but also the meaning of "developing a grain of species".

As a northern part of the potato cultivation in my country, Dingxi has been planting potatoes for more than 200 years. Relying on the strategy of potato main grain, Dingxi has continuously strengthened potato breeding and created a new system of modern potato production.

Li Deming, the head of the national modern agricultural potato industry technology system Dingxi Comprehensive Experimental Station, has been engaged in the selection of new potato varieties for more than 20 years. "Potato breeding is like pulling a child." In the sunlight greenhouse of the Dingxi Institute of Agricultural Sciences in Gansu Province, Li Deming and the team members checked potatoes and care carefully for the "golden bells".

Filtering pro -book, hybrids, real seedlings, non -sex screening, and testing tests ... A potato that adapts to local growth to complete genetic breeding work generally takes 11 years. In 200,000 to 1 million real seedlings, almost only one variety that is suitable for local planting can be selected.

"Gender resources require a generation of research personnel to optimize selection, and the spirit of struggle in scientific research is inherited from generation to generation." Zhang Ming, dean of Dingxi Academy of Agricultural Sciences, said that the precision of germplasm cultivation is high, and it is slightly a little bit refined. If you care about it, a seed cultivation must be here. After years of accumulation, Dingxi has established a potato germplasm resource database to be considered the "beef nose" that holds the germplasm resources.

In Li Deming's memory, by the end of the 1990s, local potato breeding also invited foreign experts to guide. Nowadays, the original potato breeding of Dingxi's native breeding (the hereditary traits of experts or the initial batch of seeds of the genetic traits) "Ding Potato 3" and "Ding Potato 6" and other are not only grown in the country, but also opened the international market. , Stir up the "breeding industry".

"At present, Dingxi produces over 1.4 billion potato species each year, which is equivalent to providing a potato seeds to all Chinese people each year." Said Han Yiren, director of the Potato Research Institute of Dingxi Institute of Agricultural Sciences.

In 2021, Dingxi City built 1.0231 million mu of high -quality potato seed potatoes, and the total output value of the potato industry reached 21.2 billion yuan. Today, Dingxi has become an important potato -toxic potato production and supply base, special potato production base, fresh potato planting base and deep processing base in the country.

Full -chain high standards create "authentic medicinal materials"

Traditional Chinese medicinal materials are the characteristic and advantageous industries of Dingxi City. Local -produced Angelica, Codonopsis, Astragalus, and Scutellaria baicalensis, which are produced in, are well received by customers due to high effective content and good quality. However, in the past period of time, due to the disorderly cultivation of the growers, Dingxi's medicinal resources have been mixed.

"Chinese medicinal materials do not advocate hybridization. The more pure the variety, the more stable the content." Zhang Yuyun, the head of the Shouyang District Station of the Longxi County Agricultural Technology Promotion Center in Dingxi City, said that after the importance of the medicinal material seeds of the medicinal materials Strengthen the protection of local varieties and strictly screen for new varieties selected.

After years of hard work, in 2021, Dingxi City established 160,000 acres of traditional Chinese medicine seed seed seedlings.

What are the effective content of medicinal materials? Are there any diverse agricultural metals? Nowadays, the standards for the pre -ordering of Dingxi's order have become more and more detailed for the standards of Chinese medicinal materials. Faced with the new market demand, Dingxi City sorted out and introduced the "Standards for Traditional Chinese Medicine Materials in Dingxi City", which included 71 national medicinal materials, local standards and industry standards in Gansu Province. At the same time, Dingxi City accelerated the construction of a third -party inspection and testing system for Chinese medicinal materials, and escorted the market for "Long medicine". "We have strengthened quality control from the source of seed seedlings and agricultural investment products, and forced farmers and enterprises to attach importance to the quality of Chinese medicinal materials from all aspects." Said Wei Xuebing, president of the Longxi Branch of Gansu Provincial Academy of Pharmaceutical Inspection.

In 2021, the planting area of ​​Chinese medicinal materials in Dingxi City increased from 1.5456 million acres in 2017 to 1.704 million mu, and the output value of traditional Chinese medicinal material planting industry reached 7.23 billion yuan. Ma Ping, Director of Dingxi Traditional Chinese Medicine Industry Development Bureau, said that today Dingxi City has built a Chinese herbal medicine market system for Dingxi City with Longxi Shouyang Traditional Chinese Medicine Market, Origin Market, Township Acquisition Outlets, and E -commerce. The standardization, standardization, and large -scale level have significantly improved.

Huangsha has become a dusty memory

"In the past, there were Zuo Gongli willow, which attracted the spring style of jade; today, all the people sowed green, unlimited vitality throughout Longyuan. A "Rong Ding Ecological Poverty Alleviation Fu" on the stone monument records the importance of Dingxi people to plant trees and afforestation.

Dong Junsheng, director of Forestry and Grassland Bureau of Dingxi City, has been engaged in tree planting for more than 30 years. He has personally experienced the process of Dingxi from "waste" to "green". Now he has moved from "light green" to "dark green". Dong Junsheng said that in Dingxi, you must choose a tree species with good landscapes, fast growth, and strong resistance to fight against drought, and strive to curb the loss of soil and soil, forming the ecological effects of solid carbon-oxygen-water storage-vacuum.

Over the years, in order to build the Loess Plateau ecological security barrier in the Longzhong area, Dingxi City has made a significant improvement in the human living environment through scientific afforestation. The citizens enjoyed the breeze by the flower bed and the pavilion at the door of the house, and the scene of the yellow sand was gradually buried in the memory.
