Embodiment 1

[0022] Weigh carboxymethyl starch in parts by weight: polyvinyl alcohol (17-88): citric acid: sodium iso-Vc=86.0: 8.8: 4.2: 1.0. The method for preparing the windproof and sand-fixing agent of the present invention is to add the above-mentioned parts by weight into the mixer and fully stir and mix, which is the windproof and sand-fixing agent; slowly add the above-mentioned mixed powder into 5000 parts of water and stir to make If it is fully dissolved, it will become a windproof and sand-fixing agent solution; spray the prepared sand-fixing agent solution on the surface to be protected, and spray 2 kg per square meter.

Embodiment 2

[0024] Get carboxymethyl starch in parts by weight: polyvinyl alcohol (17-88): tartaric acid: sodium benzoate=85.0: 9.0: 4.0: 1.0. The method for preparing and using the windproof and sand-fixing agent of the present invention is the same as in Example 1.

Embodiment 3

[0026] Get carboxymethyl starch in parts by weight: polyvinyl alcohol (24-88): tartaric acid: iso-Vc sodium=84.0: 8.0: 3.0: 0.8. The method for preparing and using the windproof and sand-fixing agent of the present invention is the same as in Example 1.

Abstract

The present invention relates to a windproof sand solidification agent for desert planting, belonging to the technical field of the desert control. The windproof sand solidification agent comprises the following components according to the weight portion ratio: a macromolecule binder: a film forming agent: a pH regulator: an antiseptic = (84.0-86.0): (8.0-10.0): (3.0-5.0): (0.8-1.0). When the windproof sand solidification agent is used in an arid desert area, the windproof sand solidification agent is dissolved in water according to a certain proportion and the water solution is sprayed on the sand soil surface layer around plant seeds and seedlings, and a hard shell with a certain strength can be continuously formed on the sand soil surface, thereby preventing the sand soil around the plant seeds and seedlings from being blown away by the wind, effectively reducing the water evaporation from the sand soil and providing a stable base for the growth of the plant seeds and seedlings. The windproof sand solidification agent has the characteristics of no toxicity, no harm, no corrosivity, low cost, simple preparation technology, safety, environmentally friendliness, and wide economic and social benefit.

Description

technical field [0001] The invention belongs to the field of windbreak and sand fixation, in particular to a method for preparing and using a windbreak and sand fixation agent for desert planting. Background technique [0002] Land desertification is a worldwide ecological environment problem, which seriously restricts the sustainable development of national economy. The implementation of chemical sand fixation has important practical significance for improving the survival rate of plant seedlings, curbing the process of desertification, economic development, and natural ecological environment protection. [0003] In order to fix sand, people have proposed and adopted many measures and methods, such as planting various plants to form vegetation that suppresses and covers sandy land, and protecting wind-blown sandy forest belts. Research on various windproof and sand-fixing agents has also been carried out, such as using petroleum products such as asphalt, crude oil, residua...
