From 1996 to 2005, in order to meet the great demand of cultivating high-quality wheat, systematic research and development works were carried out by the researchers from NAU focusing on the research of the physiological and ecological specialized wheat cultivars qualities along with control technology. The major route of this research focuses on the dynamic relationships between physiology, ecology and technology. By using different wheat cultivars (weak-gluten, medium-gluten, strong-gluten) as experimental materials, further comprehensively applying several modern agronomic theories and techniques, performed profound and systematical research works were carried out on laws of wheat grain quality formation, , quality physiology and ecology, ecological division of quality, adjustment and optimization of quality wheat cultivation and techniques of field management. A wheat production technological system and a model of industrialized wheat production under coordinated normalization, standardization and informatization were proposed in this project.
This project has significant innovations in theoretical research and technology extensions in the following measures: (1) systematically established laws of the quality of wheat grains depending on genotypes and environmental variation, and indexes of evaluating and improving quality specialized wheat cultivars; (2) revealed the mechanisms and principles of quality formation of different types of specialized wheat grains; (3) comprehensively illustrated the regulatory effect on the grain quality of different types of specialized wheat crops by environmental and cultivating factors such as fertilizer, moisture, temperature, density and sowing date; (4) developed a model of predicting indexes of wheat grain quality based on the effect of climatic factors; (5) formulated a system of cultivating standards and decision support for the quality of specialized wheat under coordinated indexation, normalization and informatization; and (6) created a pattern of technological service for quality wheat production based on combined agricultural extension and development.
The academic achievements made by the researchers of the project are as follows: having published 125 articles in important journals, including 12 SCI papers; published 1 monogram; developed 20 series of technical specification and two copies of route maps for adjusted and optimized wheat cultivation, and 1 system of decision support for wheat cultivation; and trained more than 37 graduate, doctorate and post-doctor candidates.
The social and economic benefits derived from this research are that the research results have been extended in wide farming areas in Jiangsu and neighboring provinces by raising the levels of quality specialized wheat cultivation and production, promoting industrialization of quality wheat production in these areas with important economic, social and ecological effects. Specifically, during 1999 to 2005, the application of this technology covered 7.0523 million mu of wheat field with an increase of economic benefit of 2.3423 billion RMB for farmers. The scientists have helped farmers constructed and extended 4 models of industrialized production of quality specialized wheat with respective characteristics, which has increased the proportion of quality specialized wheat production in Jiangsu Province from less than 5% of the total wheat production in 1999 to 83.2% in 2005, making Jiangsu Province to be the largest base of quality weak-gluten wheat production in China.
