[0054] Example: such as figure 1 As shown, a method for constructing terraces in an ecological isolation zone in a dry-hot valley includes the following steps:
[0055] S1. Select terraces on slopes with a slope of less than 25° in the dry and hot valley. The outer edge of the field 1 of the terraces is provided with a ridge 11, and two adjacent layers of field 1 are connected by a ridge 2 with a slope of less than 25° ;
[0056] S2, excavate the water-holding ditch 3 with a row spacing of 4-5m on the field 1 and trim the bottom of the water-holding ditch 3 into an inverted "V"-shaped slope; specifically, the two slopes of the inverted "V"-shaped slope and the horizontal plane The included angle is 15°;
[0057] Lay a 3-4mm thick waterproof membrane at the bottom of the water retaining ditch 3 as the water diversion layer 31;
[0058] Lay a mixture of water-retaining agent and soil on top of the water diversion layer 31 as the water-retaining layer 32;
[0059] Cover soil above the w...
