Construction method of water-storage drip irrigation system for plants

The invention discloses a construction method of a water-storage drip irrigation system for plants. The construction method includes the following steps of firstly, digging a planting pit on the earth; secondly, paving an impermeable film at the bottom of the planting pit; thirdly, mounting a water storage cover in the planting pit with the impermeable film paved; fourthly, paving a water seepage layer in a gap between the water storage cover and the planting pit; fifthly, backfilling planting soil and paving a water collection film above the planting soil; and sixthly, paving a mulching layer 8 on the water collection film. Since the water storage cover and the water seepage layer are arranged in the planting pit, rainwater in wet seasons can be stored in the water storage cover and is provided for growth of plants under action of seepage of the water seepage layer, and roots of plants can extend to absorb water conveniently. Further, by arranging the water collection film, rainwater in the wet seasons can be conveniently collected and prevented from seepage and evaporation, and loss of water in the planting pit is reduced. The construction method is simple and convenient to implement and convenient to store and utilize water, and after construction, times of manual irrigation are reduced, labor and material resource cost is saved.
