Description

Method for treating desert by using straws
Technical Field
The invention relates to the technical field of desert control, in particular to a method for controlling desert by using straws.
Background
After crops are harvested, the straw treatment problem is more and more prominent, a large amount of smoke is generated during burning, the environment is seriously polluted, and a fire disaster is easily caused. The straws are returned to the field, seeding is difficult in the next year due to the fact that the straws cannot be thoroughly smashed, emergence rate is affected, more seriously, pest eggs attached to the straws can enter soil along with the straws to breed in large quantities, grain yield reduction is caused, farmers have to use a large amount of pesticides, grain pesticide residues are caused, and various diseases are caused to people. Therefore, there is a need to develop a pollution-free straw treatment technology.
The desert control only has the tree planting and vegetation recovery, and although the desert has abundant groundwater resources, the surface layer is sand, the evaporation capacity of water is huge, the vegetation hardly survives, sand storm often occurs, the planted tree easily blows away by wind, and simultaneously, the tree root is easily exposed to the sun due to the mobility of quicksand to die. At present, people afforest and control deserts in deserts, water for plant growth is provided through artificial watering and drip irrigation technologies, but the method has the defects that a well needs to be drilled for artificial watering, the underground water level is seriously damaged, and the evaporation capacity is large when watering is carried out in summer, so that trees die due to water shortage. In winter, due to the fact that watering cannot be conducted, sand is dry, quicksand is formed under the action of wind, the sand is easily blown away by the wind, and the root of the tree is exposed to the sun and dies.
Disclosure of Invention
in order to overcome the defects in the prior art, the invention provides a method for treating desert by using straws, which provides a suitable growing environment for plants in the desert by fixing sand and ensures the survival rate of the plants, thereby achieving the purpose of improving the desert and realizing pollution-free treatment of the straws.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
A method for treating desert by using straws comprises the following steps:
S1, planting plants suitable for growth in the desert;
s2, preparing straw materials: quick lime: uniformly mixing water in a mass ratio of 1:1.5-3:8-12 to prepare slurry;
S3, coating the slurry obtained in the step S2 on the surface of the desert and the roots of the plants exposed out of the ground to obtain a slurry layer;
And S4, solidifying the sand by the slurry layer.
further, the straw material consists of headland weeds and waste crop straw.
Further, the length of the straw is less than 1 cm.
Further, the coating thickness of the slurry is not less than 0.5 cm.
further, the smearing radius of the plant root slurry is not less than 30 cm.
Furthermore, a water-retaining layer with the thickness of 5-8 cm is paved at the bottom in the planting pit when the plants are planted.
further, the water retention layer comprises a water retention agent and sandy soil, the volume ratio of the water retention agent to the sandy soil is 3-7:1, and the water retention agent and the sandy soil at the bottom of the pit are turned and stirred uniformly.
Further, the water retention layer adopts a wet application method, and the water retention agent preferentially uses a degradable water retention agent.
Compared with the prior art, the invention has the beneficial effects that:
The invention provides a method for treating desert by using straws, which comprises the steps of mixing straws, weeds and quicklime with water to prepare slurry, coating the slurry on the surface layer of the desert near plants to form a slurry layer, solidifying the slurry layer, realizing sand fixation, preventing quicksand from occurring, realizing zero-pollution treatment of the straws and increasing the income of farmers; the straw and the weeds have the water absorption and retention effects in the slurry mixing process, and meanwhile, the pores of the slurry layer are enlarged, and the water seepage rate is improved; the quicklime has the function of moisture absorption, has the effects of absorbing and retaining water, reduces the watering cost, and can prevent the evaporation of underground water after condensation; the coating radius of the slurry layer is not less than 30 cm, so that the trees are not blown away by wind, the survival rate of the trees is ensured, and meanwhile, the ground is not desertified. The desert plant planting and sand fixing method provided by the invention is suitable for desert and arid areas, plants realize natural growth after 5-8 years, desert greening, straws and weeds in the slurry layer are gradually rotted in the process, nutrients can be provided for the plants in the desert, quicklime is gradually weathered, or the plants are gradually buried and decomposed in soil after being infiltrated by rainwater, so that the plants are provided with nutrient elements such as Ga, and the underground water level gradually rises.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A desert plant planting and sand fixing method comprises the following steps:
s1, planting plants suitable for growth in the desert;
S2, preparing straw materials: quick lime: uniformly mixing water in a mass ratio of 1:1.5-3:8-12 to prepare slurry;
S3, coating the slurry obtained in the step S2 on the surface of desert and the roots of plants to obtain a slurry layer;
And S4, solidifying the sand by the slurry layer.
in this example, the straw material consists of headland weeds and waste crop straw. The length of the straw is less than 1 cm.
In this example, the slurry was applied at a thickness of not less than 0.5 cm. The smearing radius of the plant root slurry is not less than 30 cm.
In the embodiment, the proportion of the slurry is adjusted according to different desert environments; the quicklime proportion is adjusted according to the desert sand fluidity, the sand fluidity is large, and the quicklime proportion is increased; the water proportion is adjusted according to the dryness of the desert, the desert is drier, and the water proportion is increased. The optimal proportion of the slurry is that the straw material: quick lime: the water mass ratio is 1:2: 10.
In the embodiment, a water-retaining layer with the thickness of 5-8 cm is paved at the bottom in the planting pit when the plants are planted. The water retention layer comprises a water retention agent and sandy soil, the volume ratio of the water retention agent to the sandy soil is 3-7:1, and the water retention agent and the sandy soil at the bottom of the pit are uniformly stirred. The water retention layer adopts a wet application method, and the water retention agent preferentially uses a degradable water retention agent. And the water-retaining agent and the sandy soil at the bottom of the pit are turned and stirred evenly; the water-retaining agent adopting a wet application method reaches the maximum value of the water absorption capacity before application, gradually releases water after a period of time, and gradually absorbs underground water for the growth demand of plants; after raining, the water-retaining agent absorbs water rapidly, and after saturation, the infiltration speed of rainwater is reduced, so that rainwater is utilized by plants more; the water-retaining agent is mixed with sandy soil, the external water-retaining agent can not form a water-blocking layer on the internal water-retaining agent after absorbing water, and the internal and external water-retaining agents can effectively absorb water in a short time, so that the maximum water absorption rate is integrally achieved.
Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
