Description
Technical Field
The utility model relates to a planting hole is not irrigated to arid district vegetation.
Background
With the increasing severity of environmental pollution and the annual reduction of green vegetation, severe tests are provided for human living environment, particularly in the fields of agricultural production, urban greening and the like, the problems of soil caking, soil desertification and the like caused by easy loss of water in soil are solved, and therefore, how to rapidly absorb and retain rainwater or irrigation water in the soil without loss is an important research direction, and further, sufficient and slow release of water in a rhizosphere range for plants to be utilized is ensured.
Most of the existing fertilizers are only added with various nutrient components, but the problem of the moisture content of the roots of plants is less concerned, moisture is one of important factors for promoting the growth of crops, and the problems of water shortage and water shortage of soil in arid regions are solved, so that the yield of the crops is ensured, and the soil desertification is prevented.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a planting hole is not irrigated to arid district vegetation. Solves the problems of water resource shortage, low afforestation survival rate, low preservation rate, high afforestation cost and the like.
The utility model relates to a vegetation non-irrigation planting hole in arid area, which comprises a planting hole body, a cofferdam, a diversion trench, a starch pasting layer and a soil moisture preservation and restoration layer; the cofferdam is arranged around the opening of the planting hole body, the bottom of the planting hole body is provided with a soil moisture preservation and repair layer, and the upper layer of the soil moisture preservation and repair layer is provided with a starch pasting layer; the inner wall of the planting hole body is provided with a diversion ditch.
The utility model has the advantages that:
the utility model discloses combine excavation planting hole, soil moisture conservation technique and the mode of watering to the later stage need not to irrigate, can improve nursery stock survival rate, save rate and growth volume, reduces the afforestation cost. Provides necessary fertilizer for plant growth, improves the utilization rate of soil moisture, promotes the plant growth, and can be widely applied to a plurality of fields of land desertification control, agriculture and forestry crop planting, landscaping and the like.

FIG. 1 is a schematic structural view of a plant hole without irrigation for vegetation in arid regions;
fig. 2 is a schematic view showing the expansion of the inner wall of the planting hole body.
Detailed Description
The technical solution of the present invention is not limited to the specific embodiments listed below, and includes any combination of the specific embodiments.
The first embodiment is as follows: the embodiment is described with reference to the attached drawings, and the vegetation non-irrigation planting hole in the arid region consists of a planting hole body 1, a cofferdam 2, a diversion trench 3, a starch pasting layer 4 and a soil moisture preservation and repair layer 5; the cofferdam 2 is arranged around the opening of the planting hole body 1, the bottom of the planting hole body 1 is provided with a soil moisture preservation and repair layer 5, and the upper layer of the soil moisture preservation and repair layer 5 is provided with a starch pasting layer 4; the inner wall of the planting hole body 1 is provided with a diversion ditch 3.
Firstly, excavating a planting hole body according to the size, processing a diversion trench on the inner wall, then filling a soil moisture preservation and repair material at the bottom of the planting hole body, placing a seedling into the planting hole, backfilling a starch gelatinization material, and layering and compacting; after the plants are planted, a water collecting pit is formed on the upper layer and used for collecting irrigation water and precipitation.
The starch gelatinization layer in the embodiment can effectively control the soil moisture evaporation, improve the ecological function of the soil, better cooperate with the soil moisture preservation and restoration layer to achieve the aim of preserving the soil moisture for the growth of plants and promote the growth of vegetation or crops.
In the embodiment, a water flow channel is reserved on the outer ring of the starch pasting layer.
The starch gelatinization layer in the embodiment is prepared by mixing starch with mixed soil after hydrothermal gelatinization, mechanically stirring uniformly at room temperature to fully act, granulating and drying to obtain the starch gelatinization layer; the amount of starch is 15 percent of the mass of the mixed soil; the mixed soil is a mixture of clay and loess, and the mass ratio of the clay to the loess is 1: 4. Wherein the clay is laterite, montmorillonite, attapulgite, or kaolin. Before use, removing impurities from clay and loess, drying, and pulverizing.
The vegetation in this embodiment is a native vegetation with strong drought resistance.
The soil moisture preservation and restoration layer in the embodiment is a mixed soil moisture preservation and restoration agent with the weight ratio of natural sodium-based bentonite to weathered coal being 2.5:1, the fineness of natural sodium-based bentonite mineral powder and weathered coal mineral powder is more than 100 meshes, the natural sodium-based bentonite mineral powder and the weathered coal mineral powder are uniformly mixed with soil to carry out vegetation, and planting holes are used for forming planting water collecting pits for collecting irrigation water and rainfall after plants are planted in the planting holes.
The irrigation mode is that after planting, the root fixing water is irrigated once, and the irrigation is not needed in the later period.
The second embodiment is as follows: the first difference between the present embodiment and the specific embodiment is: the gutter 3 is of a reducing arc structure. The rest is the same as the first embodiment.
The arc structure that this embodiment adopted the reducing can slow down the velocity of flow, increases the detention time of moisture at the sump pit wall.
The third concrete implementation mode: the present embodiment differs from the first or second embodiment in that: the diversion ditch 3 is opened to the upper surface of the starch pasting layer 4. The other is the same as in the first or second embodiment.
The fourth concrete implementation mode: the difference between this embodiment mode and one of the first to third embodiment modes is: the ratio of the diameter of the pithead of the planting hole body 1 to the depth of the planting hole body 1 is 1 (1-2). The others are the same as in one of the first to third embodiments.
The fifth concrete implementation mode: the difference between this embodiment and one of the first to fourth embodiments is: the total thickness of the starch pasting layer 4 and the soil moisture preservation and restoration layer 5 is one third of the depth of the planting hole body 1. The other is the same as one of the first to fourth embodiments.
