won the first prize of the 2020-2021 Shennong China Agricultural Science and Technology Award for Scientific Research Achievements
.

 

Pepper is the most widely used spice crop in the world, and is widely used in the food and pharmaceutical industries, with high economic value and great development potential
.
The scale and efficiency of China's pepper industry are among the top in the world.
The output value of primary agricultural products exceeds 1 billion yuan, which is related to the income of more than 1 million rural people
.
With the rapid development of modern high-efficiency agriculture, problems such as the lack of good varieties, low level of seedling raising technology, serious obstacles to continuous cropping, serious pollution in traditional water soaking and dehulling processing, low resource utilization, and low processing efficiency and benefits have become increasingly prominent
.

 

　　The Fragrant Drink Institute of the Chinese Academy of Thermal Sciences has been conducting research on key technologies for upgrading the pepper industry chain for a long time, and has achieved key breakthroughs in the selection and breeding of new varieties, reduction of continuous cropping obstacles, ecological high-value processing technology and key equipment research and development, and new product creation.
Industrial upgrading
.
In terms of variety breeding, 78 species and 312 precious germplasm resources were collected by this achievement, and 21 excellent germplasm resources such as high resistance to blast disease and cold resistance were selected and evaluated, and the pepper germplasm resource nursery of the Ministry of Agriculture and Rural Affairs was established
.
Over many years, the excellent nationally approved new variety "Reyin No.
1" with high yield, high quality and cold resistance has been selected and bred, and the popularized planting area accounts for 95% of the country
.
A key technology for the breeding of good seedlings has been developed, and the rate of good seedlings has increased from 60% to more than 90%
.
Related varieties and technologies have been extended to high latitude and high altitude areas such as Hainan and Baoshan, Yingjiang and Luchun in Yunnan
.

　　Diversity of Pepper Germplasm Resources

 

　　Aiming at the problem of continuous cropping obstacles for stable and increased production of pepper, the results of this study found that the decrease in soil pH, the decline of microbial diversity and the autotoxicity of root exudates are the three main causes
.
Using the shade tolerance characteristics of "Reyin No.
1" pepper, the intercropping of betel nut and pepper was selected from the main tropical economic forests, and the intercropping betel nut was created to reduce the obstacles to continuous cropping and increase the yield and efficiency.
Demonstration and promotion on a large scale in China's Hainan, Yunnan, Cambodia and other places
.

　　Pepper intercropping betel nut planting base

 

　　In terms of processing, the achievement also innovatively developed ecological high-value processing technologies and supporting equipment such as pepper peel ripening, continuous peeling and degumming, and full utilization of fresh fruits, creating high value-added products, building a standardized processing technology system, and cracking the traditional soaking water peeling to make white pepper There are serious problems such as serious pollution, low resource utilization, low processing efficiency and low benefit
.
After the application of new technologies and equipment, it saves 80% of water, 65% of time, 50% of labor, 30% increase in resource utilization, and more than 5 times the added value of products.
A standardized processing technology system has been established
.
