We elaborate support system of edible fungus industry from outlook on ecological economic development, legislation and standardization of variety approval, multiple-function innovation platform of industrial development research, and perfect talent cultivation and education system. Besides, we analyze the development trend of edible fungus industry from competitive advantages, position and role in national food security, industrial development trend driven by internal demand, diversified industrial development model, division of labor within the industry, and expansion of industrial chain. Then, from the point of zoning and planning of edible fungus industry, we put forward suggestions that it should start from modern industrial system and take the industrial cluster development and optimization as guidance. In addition, we present technical innovation direction of industrial development. It is proposed to strengthen propaganda, build industrial cultural atmosphere, and expand social cognition degree of edible fungus industry to promote its redevelopment. Finally, it is expected to promote international influence of edible fungus industry through experts appealing for policy support.

作者： LU Min, LI Yu*College of Agronomy, Jilin Agricultural University, Changchun, Jilin 130118, China

The present status and operation of the mushroom industry in China are summarized in terms of environmental and economic cycles, variety diversity, breeding of high quality varieties, features associated with developing mushroom industry models, evolving cultivation techniques, health functions and environmental protection. The advantages enjoyed by China′s mushroom industry such as strain resources, raw material and labor resources, and varied climatic conditions are also explored. Problems relating to resource protection, new germplasm preservation and breeding, variety protection and associated policies and laws, the need to manufacture finished and highly processed mushroom products, industrialization, industrial clustering, optimization of industry structure, mycology training, lack of multi-skilled teams with different experience levels, and the need to foster reserves of talent are discussed. Projections are also made for the future development of China′s mushroom industry.

Journal of Integrative Agriculture 2005年第9期 685-692页

作者： WU Jing-gui, WANG Ming-hui, JIANG Yi-mei and XU Yan College of Resource and Environment Sciences, Jilin Agricultural University, Changchun 130118, P.R.China

Spectroscopy measurements (Fourier transform infrared differential spectroscopy, Carbon-13 nuclear magnetic resonance spectrometry, Matrix-assisted laser desorption/ionization-time of flight mass spectrometry) were performed to study the humic acids of the soil applied with corn stalk. The results showed that after incorporation of corn stalks into the soil, the soil humic acid (HA) changed significantly in different stages. During first 60 days, new HAs were formed by polymerization and seems to be similar to that of initial HAs from composting corn stalk, some little molecular organic matters also reacted with soil HAs and turned into parts of soil HAs. After 60 days of the corn stalk residue incorporation, new HAs were formed by polymerization of decomposed lignin molecules, some methylenes transformed into methyls and methoxyls since the 90th day. Application of corn stalk led to the increase of aliphatic components in soil HAs, the decrease in aromatic components of soil HAs and the suppression in oxidation degree of soil HAs. The average molecular weight of soil HAs also declined because of application of corn stalk.

Nanostructured columns with a length about several tens of micrometer and a diameter of about 80 nm were obtained by molecular recognition directed self-assembly of a pair of comple- mentary molecular components, 4-amino-2 , 6-didodecylamino-1 , 3, 5-triazine(M) and 5- (4-dode- cyloxybenzylidene )-(1H, 3H)-2, 4, 6-pyrimidinetrione (B) in chloroform. In this system, with positive cooperativity, π-aromatic stacking and van der Waals interactions as well as hydrogen bonds cause the formation of the nanocolumns.
