在中学里,建立一个一池多用的小型动物饲养池(图3,见封三),将有助于动物教学活动的开展,并对培养学生自幼热爱生物科学大有好处。一、饲养池的建造饲养池位置的选择,应与生物园组成一个整体。池的大小可根据生物园场地条件进行设计。我校建造的动物饲养池长650厘米,宽300厘米(图1),蓄水部位深120厘米,水平面以上高120厘米,陆地部位高于水平面20厘米,其斜坡为15度左右。贮水池用水泥和碎石铺底约10厘米厚,从池底向上用水泥沙浆砌砖墙,并用水泥沙浆涂面,严防漏水。在100厘米高处,池內侧留10厘米宽的平板道(图2),平板道内设串
In secondary schools, the establishment of a multi-purpose pool for small animals (Figure 3, see cover three) will facilitate the teaching of animals and will be of great benefit to developing students’ love of biological science at an early age. First, the rearing pond construction Rearing pond location selection, and the biological park should be formed as a whole. The size of the pool can be designed according to the conditions of the Bio Park. The animal breeding pond constructed by our school is 650 cm long and 300 cm wide (Figure 1). The water storage area is 120 cm deep and 120 cm above the water level. The land area is 20 cm above the horizontal and its slope is about 15 degrees. Storage tank with cement and gravel paved about 10 cm thick, up from the bottom of the pool with cement mortar brick wall, and cement mortar coated to prevent leakage. At a height of 100 cm, a 10 cm-wide slab track is left inside the tank (Figure 2) and a slab track
