Based on Yunnan's natural endowments, ecological diversity, variety of crops, and location along the border.
Focusing on local needs, reflecting various combinations, highlighting ecological characteristics, and giving play to regional advantages.
Research features:
1. Crop Genetic Improvement and Utilization of Heterosis
Based on Yunnan's unique geographical ecology and abundant germplasm resources advantages, combined with the actual production of crops in Southwest my country - plateaus and mountainous areas, adjacent to Southeast Asian countries, Yunnan-type rice sterile cytoplasm, and Yunnan-specific corn, wheat and other crop resources are used as the Based on the foundation, explore various crop-specific resources in Yunnan, focus on breeding high-yield hybrid combinations and high-quality varieties suitable for southwest China and Southeast Asia, and carry out functional gene mapping, cloning, isolation and functional analysis of crops, and carry out molecular design of crops. Breeding to ensure the stability and safety of grain yields in Yunnan and even my country.
2. Crop Physiological Ecology and Yield Quality Formation
Taking advantage of the ecological conditions of Yunnan's low-latitude plateau and combining with the needs of Yunnan's pillar characteristic industries, research on the physiological ecology and high-quality and efficient cultivation of crops, especially flue-cured tobacco, potatoes, and sugarcane, is carried out. In the 1940s, Professor Xu Tianliu, a returned scholar who stayed in France, took the lead in introducing and cultivating improved varieties of flue-cured tobacco, and was known as the "Father of Yunyan". In the 1970s, Professor He Shunchang carried out research on sugarcane resources and cultivation technology, and his achievements won the second prize of the National Science and Technology Progress Award in 1988. At present, the leader of this direction is an expert in the cultivation position of the national potato industry technology system. The research on the physiology and nutritional quality of potato cultivation is at the leading level in China.
3. Crop Diversity and Sustainable Mountain Agriculture
In view of the fact that Yunnan is located in the plateau, with large altitude difference, diverse climate and environment, large proportion of sloping farmland, serious soil erosion, etc., with the goal of making full use of climatic resources, rational use of land resources, and achieving a win-win situation in economic and ecological benefits, intercropping and multiple cropping are carried out. Diversity planting, conservation tillage measures and mechanism research. Based on the spatial and temporal configuration of corn and potatoes, beans, vegetables, corn and sugarcane, a variety of modes and cultivation measures such as contour planting and straw mulching were screened. It is featured in the selection of diverse planting patterns, the research on maintaining tillage measures, and its integration with engineering and biological measures to improve the productivity and sustainability of mountain crop systems.
4. Innovation and utilization of medicinal plant germplasm
Yunnan is the province with the most abundant medicinal plant resources in my country, accounting for more than half of the country's total. Taking Panax notoginseng, Dendrobium, Rhizoma Paridis, Gastrodia, Erigeron breviscapus and other authentic and characteristic medicinal plants in Yunnan as the research objects, the functional gene verification of important traits of medicinal plants, the mining and utilization of excellent genes for quality traits of medicinal plants, and medicinal Gene mining and utilization of important agronomic traits of plants, germplasm innovation and utilization based on quality traits and agronomic traits of medicinal plants, formation mechanism and regulation of quality and yield of Chinese medicinal materials, physiological mechanism of stress resistance regulation of medicinal plants, The research on the adaptation mechanism of special habitats focuses on the key common technical problems in the production practice of traditional Chinese medicinal materials in Yunnan, and takes the analysis of basic theoretical problems as a breakthrough to promote the solution of production technology problems, accelerate the technological innovation of the traditional Chinese medicinal materials industry in Yunnan Province, and promote the sustainable health of the industry development.
