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

A kind of agent of checking winds and fixing drifting sand for desert planting
Technical field
The invention belongs to the field of checking winds and fixing drifting sand, be specifically related to a kind of preparation and application of the agent of checking winds and fixing drifting sand for desert planting.
Background technology
Desertification is a worldwide ecological environment problem, has seriously restricted the Sustainable development of national economy.Implement chemical sand-fixing, for improving plant seedlings surviving rate, check Desertification process, Economic development, natural ecological environment protection etc. is all had important practical significance.
People, in order to fix the sand, propose and have adopted many Measures, for example, plant various plants and form the vegetation that suppresses and cover sand ground, protection dust storm forest belt etc.Also carried out the research of the various agent of checking winds and fixing drifting sand, for example utilize the petroleum productss such as pitch, crude oil, residual oil, heavy oil as checking winds and fixing drifting sand agent, with the macromolecular materials such as polyacrylamide as check winds and fix drifting sand agent and with inorganic salt (water glass etc.), urea etc. as the agent of checking winds and fixing drifting sand.But, up to now, these check winds and fix drifting sand agent and materials, or sand-fixing effect is poor, or price is high, or enter sand bed and cause secondary pollution, thereby be difficult to spread and use.
The agent of checking winds and fixing drifting sand provided by the invention, its main component is modified natural polymer solid state powder, nontoxic, tasteless, during use, add a certain amount of water dissolution, then be sprayed at uniformly exposed sandy soil surface, after moisture evaporation, loose tiny sandy soil particle formation thickness is the tectum of 1 centimetre of left and right, there is certain intensity, below loose sandy soil are covered, can play condensation cure effect to sand dune or sandy earth's surface, seven, the wind of eight grades can not cause airborne dust yet, can prevent that wind-force deflation has again the bonding course that keeps moisture and improvement sand ground character, to reach control and to improve sand damage environment, improve the object of sand ground plant growing surviving rate.Contriver is through test of many times, by originally checking winds and fixing drifting sand, the agent aqueous solution is sprayed at around plant seedlings, can effectively prevent that plant seedlings sandy soil are around blown to four winds, for plant seedling growth provides stable basis, can also effectively reduce the evaporation of moisture in sandy soil, the agent environmental protection of checking winds and fixing drifting sand, cheap, effect are significantly, also can not exert an influence to the growth of plant simultaneously.Current China territory Desertification is day by day serious, and the financial loss causing every year, up to tens billion of units, as the agent of originally checking winds and fixing drifting sand is applied to desert planting, can be brought huge economic benefit and social benefit surely.
Summary of the invention
The object of the invention is for the problem existing in desert afforestation, the preparation and application of a kind of efficient, environmental protection, the cheap agent of checking winds and fixing drifting sand is provided.
Contriver finds through a large amount of experimental study, and using modified natural polymer material is main raw material, can prepare a kind of efficient, environmental protection, cheap Novel wind-proof sand-fixation agent, and the technical scheme that realizes the object of the invention is specific as follows:
The one agent of checking winds and fixing drifting sand, is characterized in that being comprised of according to the following number of weight ratio following component:
High polymer binder: membrane-forming agent: pH adjusting agent: sanitas=84.0~86.0: 8.0~10.0: 3.0~5.0: 0.8~1.0.
Wherein, biodegradable high polymer binder is selected from carboxymethyl starch or hydroxyethylamyle; Membrane-forming agent is selected from polyvinyl alcohol (24-88) or polyvinyl alcohol (17-88); PH adjusting agent is selected from citric acid or tartrate; Sanitas is selected from different Vc sodium or Sodium Benzoate.
Preparation and the described agent of checking winds and fixing drifting sand of use, be comprised of following step:
(a). batch mixing: by above-mentioned parts by weight, use blender fully to mix, be finished product;
(b). dissolve: above-mentioned mixed powder is slowly added to the water and is stirred, make it abundant dissolving;
(c). spray: the above-mentioned aqueous solution is placed in to sprinker, by 2kg/m 2consumption, to sandy soil top layer, evenly spray.
Advantage of the present invention and beneficial effect are as follows:
The agent of checking winds and fixing drifting sand of the present invention, nontoxic, harmless, non-corrosiveness, scientific formulation is reasonable, with low cost, and preparation technology is simple, and safety, environmental protection, energy-conservation, while being sprayed at sandy soil surface, can form on surface continuously and have the duricrust of some strength, the sand drift of dispersion is closed in below duricrust, thereby play the effect of checking winds and fixing drifting sand, be described as follows:
1. check winds and fix drifting sand effective: on sandy soil top layer, forming thickness is the tectum of 1 centimetre of left and right, and the wind of seven, eight grades can not cause sand yet;
2. long-lasting good: to press 2kg/m 2sprinkling is checked winds and fixed drifting sand after agent, and the insolation of sandy soil surfaces bonding course experience daylight, wind and weather 180 days are unchanged; Can effectively prevent that plant seed, seedling sandy soil are around blown to four winds, and can also effectively reduce the evaporation of moisture in sandy soil simultaneously, for plant seed, growth of seedling provide stable basis;
3. biodegradable: the agent of checking winds and fixing drifting sand can natural degradation be fertilizer, environmentally safe;
4. the main raw material of preparing the agent of checking winds and fixing drifting sand is modified natural polymer material; according to acute toxicity grading criteria regulation in the China month state < < HJ/T 154-2004 of State Environmental Protection Administration of people's republic novel chemical substance hazard evaluation guide rule > >, this agent of checking winds and fixing drifting sand belongs to " actual nontoxic level ".
