In the wandering earth, the most impressive thing can be said: "Moss will start the space program, the pilot space station will refrigerate 300,000 human fertilized eggs, and the seeds of 100 million basic crops." At the critical moment, crop seeds are more important than life for the sustainable development of mankind. The reason why it is so easy to understand is that humans start with fertilized eggs, and most of the crops start from seeds, so saving seeds is actually continuing life. At present, in the development of agriculture, we are doing the same thing, that is, using germplasm resources to protect and preserve crops and forest germplasm resources.
Corn, rice, wheat, potatoes, tomatoes, peppers, etc., were not what we saw at first, but were cultivated by humans, and the results of the improvement of excellent varieties were selected, and genetic materials were needed to create new varieties. Where do these genetic materials come from, they are obtained from germplasm resources. Therefore, the use of germplasm resources to protect and preserve crops and forest germplasm resources is of great significance to the sustainable development of agroforestry and human sustainable development.
In the 1970s, the number of seed banks in the world was less than 10, and the number of germplasm resources preserved was only 500,000. In the 1980s, the United States established the Fort Collins genebank in Colorado, collecting in this genebank. More than 200,000 copies of germplasm; entering the millennium, the British Wickhurst Millennium Seed Bank was built; six years later, more than 500 genebanks of various types have been built in the world, and more than 1.8 million germplasm resources have been collected. In 2007, there were already 1,400 seed banks in the list of the UN Food and Agriculture Organization; in 2008, the human “Noah’s Arkâ€, which is well known to the world, was put into use in Norway’s Svalbard Global Seed Bank. The more and more germplasm resources are built, the more shelters there are, and more and more germplasm resources are preserved and preserved. Food security and human development have added a guarantee.
