ABSTRACT: In the world, there are more than 6 million germplasm resources, of which more than 90% are seeds. It is urgent to protect these germplasm resources.
Firstly, several methods of wheat seed drying and preservation and their characteristics were introduced. Microwave drying equipment and desiccant drying were commonly used. Now heat pump drying and microwave drying were developed. Then, the optimum water content and vigor of wheat seeds were analyzed. The results showed that the germination rate of dried seeds was high and the vigor was strong, indicating the moisture content of seeds. Quantity has a great influence on seed vigor of wheat.
The development of social economy has led to a large consumption of resources, and the non-renewable earth resources are gradually exhausted, so people have increased the protection of resources. At present, human production activities have a serious impact on various renewable and non-renewable resources.
