成鱼塘要护好坡,首先要弄清塘坡易损的原因,然后针对性的采取措施,才能收到理想的效果。笔者通过几年的实践,认为成鱼塘塘坡易损不外乎以下四种原因: 1.坡比过小,有的不足1:1。加修土层不厚,新老土粘合不牢,波浪与流坡的接触不是滑行,而是激烈冲击,导致新土很快下滑。 2.由于各种肥料集中施在塘的四周边上,导致塘边淤泥土质肥沃松软,结构不强,见水后易随水流失。 3.新修塘坡尚未全干开裂,就急于进水放鱼,大雨洗涤流失严重,波浪一冲即垮。
Into the pond to protect the slope, we must first clarify the reasons for pond vulnerability, and then take targeted measures to receive the desired results. Through several years of practice, the author thinks that the pond becomes vulnerable to the following four reasons: 1. Slope is too small, some inadequate 1: 1. Soil amendments are not thick, the old and new soil adhesion is not strong, the waves and the slope of the contact is not a taxi, but a fierce impact, resulting in a new soil soon decline. 2. As a result of a variety of fertilizers concentrated in the pond around the edge of the pond led to fertile soil soft silt, the structure is not strong, easy to see the water with the water loss. 3. newly built pond slope not yet cracked, it is eager to water into the fish, heavy rain washed drastic loss of a wave that collapse.
