Abstract
The present invention relates to the field of ecological restoration and desert control, especially to applications of etherified corn starch, a sand fixation water retention agent, and a preparation method of the sand fixation water retention agent. The technical scheme for achieving the purpose of the present invention comprises applications of etherified corn starch in sand fixation water retention, a biodegradable sand fixation water retention agent containing the etherified corn starch, and a preparation method of the biodegradable sand fixation water retention agent. According to the present invention, the corn starch and the plant cellulose are adopted as the main raw materials, other chemical components are not contained, and advantages of no environment pollution, biodegradability, strong water absorption, rich nutrition elements, and plant growth promoting are provided.
Description
technical field [0001] The invention relates to the fields of ecological restoration and desert control, in particular to the application of etherified cornstarch, a sand-fixing and water-retaining agent and a preparation method thereof. Background technique [0002] China is one of the countries in the world with a large area of desertification and serious damage. The area of desert and desertified land is 1.49 million km 2 , of which the desertified land area is 334,000 km 2 . The annual direct economic loss caused by desertification is about 54 billion RMB, which has a serious impact on industrial and agricultural production, people's life and human health. Desertification has become one of the most serious ecological and environmental problems in my country at present. Therefore, many scholars have carried out relevant research on the prevention and treatment of desertification. There are three relatively mature sand fixation methods: engineering sand fixation, pl...
