Description
Technical Field
The invention relates to the technical field of desert greening, in particular to a desert greening method.
Background
A large area of desertified land exists in the north of China, and the desertified land is counted to be more than 150 ten thousand square kilometers. More seriously, the desertification shows a gradually increasing trend, and great threat is caused to the ecological environment in the north of China. Meanwhile, the method also causes great harm to industrial and agricultural production in relevant areas and life of people, and seriously influences the development of social economy.
Based on the severity of desertification hazards, the use of artificial vegetation to control sand damage has been a history for decades and is one of the most effective methods for the internationally recognized ecological reconstruction of sandy areas. The method is mainly developed by planting drought-enduring plants in desert, such as by aerial planting of pasture and planting of shrubs for greening desert, but the technology has some effects on the treatment of sand in gentle areas with certain vegetation, but the effect is not obvious on sand with high fluidity or windy sand all the year round. The main reason is that the grass seeds and shrub seeds are easily blown away by wind and difficult to realize field planting. Secondly, the flowing sand often buries the seeds which have germinated and emerged, and further causes large-area dead seedlings.
Disclosure of Invention
The invention aims to provide a desert greening method which is convenient to operate and can effectively overcome the defects that vegetation is not easy to survive and dead seedlings are high, thereby achieving the purpose of better greening effect.
In order to solve the technical problem, the invention provides a desert greening method, which comprises the following steps:
firstly, digging a sand to be greened into a concave cavity as a fish on-earth by using a crawler-type digging machine;
secondly, paving protective nets on the concave cavities and the sand on the outer edges of the concave cavities;
thirdly, mixing plant seeds with strong drought resistance, water-retaining foam and low-grade concrete, and pouring the mixture on a protective net to form cured concrete;
and fourthly, spraying a proper amount of water to the solidified concrete to ensure the growth of drought-resistant greening new seedlings.
Preferably, in the first step, a crawler-type excavator is used to excavate the sand to be greened into a plurality of concave cavities for the solidification of the water-retaining residual water as a patch of fish, the distance between two adjacent concave cavities being 3-5 m.
Further preferably, in the second step, the protection net is woven by hemp ropes or iron wires.
Preferably, in the third step, plant seeds with strong drought resistance, a water-retaining agent and low-grade concrete are mixed and poured on the protective net to form cured concrete.
Further preferably, in the third step, plant seeds with strong drought resistance, water-retaining foam or water-retaining agent and low-grade concrete are mixed and poured on the protective net to form the cured concrete with the thickness of 5-35 cm.
The invention has the beneficial effects that: the present invention excavates the sand to be greened into a concave cavity as a fish on-and-as-a-land lump, and then lays a protective net on the concave cavity and the sand on the outer edge of the concave cavity; then plant seeds with strong drought resistance, water retention foam and concrete with low marks are mixed and poured on the protective net to form cured concrete, the cured concrete is sprayed with proper water to ensure the growth of new drought-resistant greening seedlings, the concave cavities are fixed through the protective net by arranging the sand, the plant seeds are poured on the protective net to form the cured concrete, so that the fixed growth of the plant seeds is facilitated, the greening operation is convenient, the defects that vegetation is not easy to survive and dead seedlings are high can be effectively overcome, and the purpose of better greening effect is achieved.
Detailed Description
The present invention will be described in further detail with reference to examples.
Example one
A desert greening method comprises the following steps:
firstly, digging sand to be greened into irregular concave cavities for solidifying water retaining residual water as a fish on field by adopting a crawler-type digging machine; the remaining water in the field is solidified and the distance between two adjacent concave cavities is 3-5m, so that every fish pond and/or rice field can gradually form an integral greening area.
Secondly, paving protective nets on the concave cavities and the sand on the outer edges of the concave cavities; the protective net is woven by hemp ropes or iron wires, so that the protective net can be conveniently detached after the plant seeds grow and are stably rooted;
thirdly, mixing plant seeds with strong drought resistance, water-retaining foam and low-grade concrete, and pouring the mixture on a protective net to form cured concrete; the purpose is that plant seeds can be conveniently fixed on the solidified concrete to smoothly grow, cannot be blown away by wind, and cannot be buried by flowing sand; the plant seeds with strong drought resistance, the water retention foam or the water retention agent and the low-grade concrete are mixed and poured on the protective net to form the solidified concrete with the thickness of 5-35cm, so that the continuous sand collapse of the edge of the sand land can be prevented, and the plant growth can be facilitated.
And fourthly, spraying a proper amount of water to the solidified concrete to ensure the growth of drought-resistant greening new seedlings.
Example two
A desert greening method comprises the following steps:
firstly, digging sand to be greened into irregular concave cavities for solidifying water retaining residual water as a fish on field by adopting a crawler-type digging machine; the remaining water in the field is solidified and the distance between two adjacent concave cavities is 3-5m, so that every fish pond and/or rice field can gradually form an integral greening area.
Secondly, paving protective nets on the concave cavities and the sand on the outer edges of the concave cavities; the protective net is woven by hemp ropes or iron wires, so that the protective net can be conveniently detached after the plant seeds grow and are stably rooted;
thirdly, mixing plant seeds with strong drought resistance, water-retaining foam and low-grade concrete, and pouring the mixture on a protective net to form cured concrete; the purpose is that plant seeds can be conveniently fixed on the solidified concrete to smoothly grow, cannot be blown away by wind, and cannot be buried by flowing sand; the plant seeds with strong drought resistance, the water retention foam or the water retention agent and the low-grade concrete are mixed and poured on the protective net to form the solidified concrete with the thickness of 5-35cm, so that the continuous sand collapse of the edge of the sand land can be prevented, and the plant growth can be facilitated.
And fourthly, spraying a proper amount of water to the solidified concrete to ensure the growth of drought-resistant greening new seedlings.
The desert greening of the present invention is further explained by the example data of greening:
thickness of the sand fixation bonding layer: after the sand-fixing bonding layer was stably formed, the thickness was measured.
Wind erosion resistance: and measuring the mass loss rate (mass loss for short) and the strength loss rate (strong loss for short) of the sand-fixing bonding layer under a specific wind speed condition, wherein the mass loss rate and the strength loss rate are one month under the condition of 20km/h wind speed.
Moisture retention: water content in the sand-fixation binding layer.
See table one for details:
watch 1
From the specific data in the table, the plant seeds with strong drought resistance, the water retention foam and the low-grade concrete are mixed and poured on the protection net in the concave cavity, so that the sand can be stabilized, the wind erosion resistance of the plants is high, the water required by the growth of the plants is provided, and the survival rate of the plants is effectively improved.
