Embodiment 1

[0054] 1. Preparation of superabsorbent

[0055] Add 10 g of cornstarch into a three-necked flask of 100 ml of deionized water, stir at a speed of 300 r / min, control the temperature at 70° C., gelatinize for 1 hour and then cool to room temperature. Add 50g of acrylic acid into the beaker, then add 50g of 20% sodium hydroxide solution, and transfer it to a three-necked flask after neutralization. Then add 1.0 g of sodium persulfate and 0.3 g of N,N-methylenebisacrylamide to replace the air in the system with nitrogen, adjust the temperature to 70°C, and react for 2 hours to obtain a transparent gel block. Dry in an oven at 80° C. for 5 hours to obtain a superabsorbent precursor. Then pulverize it and pass through a mesh sieve to obtain a colorless and transparent granular superabsorbent.

[0056] 2. Superabsorbent mixed with other raw materials

[0057] Add 50g of biological organic matter, 50g of bentonite, 50g of nutrient element mixture, 50g of organic fertilizer and 50g...

Abstract

The invention relates to a degradable desert sand fixing agent. The desert sand fixing agent mainly solves the problems of poor wind erosion resistance and non-degradation of existing desert sand fixing agents. The degradable desert sand fixing agent comprises, by mass, 10-40% of a super absorbent, 5-25% of biological organic matters, 5-25% of bentonite, 5-25% of a nutrient element mixture and 5-25% of an organic fertilizer. The degradable desert sand fixing agent well solves the technical problems, and can be used for desert greening ecological restoration.

Description

technical field [0001] The invention relates to a degradable desert sand-fixing agent, its preparation method and its application in desert afforestation. Background technique [0002] Land desertification has become a major environmental and social problem that threatens the human living environment and affects the sustainable development of society. The land affected by desertification in the world accounts for 1 / 4 of the global land area, and the population affected by desertification accounts for 1 / 3 of the world's total population. As of 2014, the total area of ​​desertified land in my country has reached 2.6116 million square kilometers, accounting for 27.20% of the total land area. Among them, the Xinjiang region is most seriously affected by desertification, and the desertified land area has reached 1.0706 million square kilometers. Wind and sand hazards such as strong winds, sandstorms, blowing sand, and floating dust have a huge impact on the production and life o...
