Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of irrigation-free planting hole and specifically relates to a drought area vegetation irrigation-free planting hole. BACKGROUND

[0002] In order to avoid land desertification and desertification, the land in the drought area needs to be covered with vegetation. However, due to the water and soil conditions in the drought area, the vegetation cannot be planted in the traditional way. Therefore, at present, the drought area is prepared for planting by using the irrigation-free planting hole.

[0003] However, the irrigation-free planting hole at present mainly uses deep holes with certain waterproof measures. In order to save as much water as possible, waterproof measures are mostly set at the bottom of the hole to prevent water loss at the bottom of the ground. However, the water retention capacity of such planting hole is limited. This is because the diameter of the top opening is mostly larger than the diameter of the bottom, so the evaporation is large and the precipitation is directly retained on the waterproof layer. Once the precipitation is large, the soil will not absorb enough water. In view of this, the above problems are studied in depth, and the case is generated. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies of the prior art, the utility model provides a drought area vegetation irrigation-free planting hole, which solves the problems of the prior art.

[0006] The diameter of the bottom of the planting pit is larger than the diameter of the top opening, and the position of the diameter change in the planting pit is changed by a conical section.

[0007] The starch gelatinization layer is a circular table type structure, and the diameter of the starch gelatinization layer matches the diameter of the top opening of the planting pit.

[0008] A flow guide groove is arranged around the top opening of the planting pit, and the flow guide groove extends through the conical section downward to the soil moisture conservation repair layer.

[0009] Preferably, the conical section is a truncated conical structure, the top diameter of the conical section matches the diameter of the top opening of the planting pit, and the bottom diameter of the conical section matches the diameter of the bottom of the planting pit.

[0010] Preferably, the diameter ratio of the top opening diameter of the planting pit to the bottom diameter of the planting pit is 0.8.

[0011] Preferably, the top of the flow guide weir is covered with a waterproof layer.

[0012] Preferably, the total thickness of the starch gelatinization layer and the soil conservation repair layer is one third of the depth of the planting pit. Advantages

[0017] The technical scheme in the embodiments of the utility model will be apparently and completely described below in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range protected by the utility model.

[0018] Please refer to Figs. 1-2 The utility model provides an implementation scheme: in the modern dry area planting process, in order to make the plant growth moisture more sufficient as far as possible, the non-irrigation planting hole mode is usually adopted, however, the non-irrigation planting hole at the present stage such as CN215074154U discloses a dry area vegetation non-irrigation planting hole, the hole mouth of the planting hole is greater than the bottom diameter, in this way, the evaporation amount of the non-irrigation planting hole is large, and the rainwater entering the planting hole is absorbed in the way of flat laying, therefore, the rainwater that does not settle in time is easy to be irradiated, not only easy to cause rainwater evaporation, but also easy to cause the water temperature to rise and burn the plant.

[0019] According to the drawings in the specification Figs. 1-2It can be known that, in order to solve the above problems, the application discloses a dry area vegetation non-irrigation planting hole, which comprises a planting pit 1, the planting pit 1 is arranged below the ground, a flow guide weir 2 is arranged on the periphery of the planting pit 1, the flow guide weir 2 has a flow guiding effect on rainwater, so that the rainwater flows into the planting pit 1 from the flow guide weir 2, plants are planted in the planting pit 1, a soil conservation restoration layer 3 is arranged at the bottom of the planting pit 1, a starch gelatinization layer 4 is arranged on the soil conservation restoration layer 3, the soil conservation restoration material is filled and arranged at the bottom of the planting hole body, seedlings are put into the planting hole, the starch gelatinization material is backfilled, and the starch gelatinization layer 4 is covered on the soil conservation restoration layer 3, so that the starch gelatinization layer 4 and the soil conservation restoration layer 3 play the role of collecting irrigation water and precipitation;

[0020] Furthermore, the diameter of the bottom of the planting pit 1 is greater than the diameter of the top opening, and the position where the diameter of the planting pit 1 changes is connected through a conical section 5, the diameter of the opening and the bottom of the planting pit 1 changes, so that the planting pit 1 has a structure of being narrow at the top and wide at the bottom, so that the light irradiates the planting pit 1 for the shortest time, thereby avoiding excessive evaporation of water;

[0021] Furthermore, the starch gelatinization layer 4 has a circular table type structure, the diameter of the starch gelatinization layer 4 matches the diameter of the top opening of the planting pit 1, so that the starch gelatinization layer 4 can guide the flow of rainwater, and ensure that the rainwater is deposited on the periphery of the soil conservation restoration layer 3, because the diameter of the top of the planting pit 1 is smaller than the diameter of the bottom, so the peripheral rainwater cannot be irradiated, on the one hand to avoid evaporation, on the other hand to avoid soil warming;

[0022] Furthermore, a flow guide groove 6 is arranged on the top opening of the planting pit 1, the flow guide groove 6 extends through the conical section 5 to the soil conservation restoration layer 3, and the flow guide groove 6 can effectively guide the flow of rainwater.

[0023] As a preferred scheme, further, the conical section 5 has a truncated conical structure, the diameter of the top of the conical section 5 matches the diameter of the top opening of the planting pit 1, and the diameter of the bottom of the conical section 5 matches the diameter of the bottom of the planting pit 1, thereby improving the structural strength and filtering effect of the non-irrigation planting hole.

[0024] As a preferred scheme, further, the diameter ratio of the top opening diameter of the planting pit 1 to the bottom diameter of the planting pit 1 is 0.8.

[0025] As a preferred scheme, further, a waterproof layer 7 is arranged on the top of the flow guide weir 2, and the wall surface rainwater is excessively absorbed by the flow guide weir 2.

[0026] As a preferred scheme, further, the total thickness of the starch gelatinization layer 4 and the soil conservation restoration layer 3 is one third of the depth of the planting pit 1.
