Construction method of plant water storage bottom irrigation system

technical field

The invention relates to the technical field of plant water replenishment, in particular to a construction method of a plant water storage bottom irrigation system. the

Background technique

In agricultural production, afforestation and landscaping projects, water-saving irrigation for plants has always been a problem. In the wet season, there is a lot of rain, and a large amount of rainwater is lost because it cannot be stored. In the dry season, due to the lack of rainfall, some plants are often due to Withered due to lack of water; in the prior art, the irrigation of plants generally adopts green sprinkler, regular sprinkler irrigation or drip irrigation and micro-spray technology. These methods not only require a lot of manpower and material resources, but also require regular inspection and irrigation. High, time-consuming, labor-intensive, and consume a lot of fresh water resources, and neither can solve the problem of rainwater leakage, nor can it solve the problem of water evaporation, especially in desert or saline-alkali areas, due to the shortage of fresh water resources or less rainfall, The above methods are difficult to popularize and use. the

Detailed ways

As shown in the figure, a construction method of a plant water storage bottom irrigation system includes the following steps:

a) Excavate the planting pit 1 on the ground, the depth and width of the planting pit are set according to the size and growth habit of the transplanted plant, and the shape of the planting pit can be circular, square or strip;

B) laying anti-seepage film 2, laying anti-seepage film 2 on the bottom inner wall of planting pit 1;

c) install the water storage cover 3, install the water storage cover 3 in the planting pit where the anti-seepage film 2 has been laid, the bottom opening of the water storage cover 3 is closed at the top, and is buckled at the bottom of the planting pit 1; preferably, the water storage cover 3 is rigid material; in order to save costs, in the present embodiment, the water storage cover uses flexible materials such as plastic films, and in order to enhance the rigidity of the water storage cover, a support frame 31 is provided on the inside of the water storage cover 3 to prevent planting pits 1 and the soil above the water storage cover 3 collapses. the

d) Laying the water seepage layer 4, filling the water seepage layer 4 in the gap between the planting pit 1 and the water storage cover 3, the filling material of the water seepage layer 4 is plant straw, sand and stones, etc., the height of the water seepage layer 4 is the same as that of the water storage cover 3 at the same height;

e) Backfilling the planting soil 5 and laying the water collecting diaphragm 6, planting the plants in the planting pit 1 and backfilling the planting soil to form the planting soil layer 5, laying the water collecting diaphragm 6 above the planting soil layer 5, the middle of the water collecting diaphragm 6 The position is concave, the trunk of the plant passes through the through hole 7 on the water collection diaphragm 6, and the lowest point of the water collection diaphragm is the through hole 7 that the plant passes through. Preferably, when the shape of the planting pit is strip-shaped, the water collection diaphragm The shape of 6 is "V" shape; when the planting pit is round or square, the shape of water collecting diaphragm 6 is pot bottom shape or funnel shape, and the shape of water collecting diaphragm 6 is set to "V" shape, pot bottom shape or funnel shape shape, which is convenient for rainwater collection and downward penetration of rainwater; when laying, the water storage volume of the water collection diaphragm 6 is compatible with the sum of the volumes of the water seepage layer 4 and the water storage cover 3;
