Experiment of Three-Dimensional Planting and Aquiculture of Peach and Soft-Shelled Turtle
In order to solve the bottleneck problems of single variety of peach planting,short fruit picking period and large ditch area,a productive experiment of three-dimensional planting and aquiculture of peach and soft-shelled turtle was carried out,the planting and aquiculture system was constructed,the test area was 3.33 hectares,the ratio of planting area to aquiculture area was 9:1.The results showed that aquiculture water quality indexes such as TAN,NO2--N and NO3--N were stable and kept within an ideal range in the three-dimensional planting and aquiculture mode of peach and soft-shelled turtle.COD,TSS,TN and TP were all better,which met the discharge standards of freshwater aquaculture.The pH was slightly alkaline and remained between pH 8.2 and pH 9.5.The yield of peach was 15 t/hm2,and the SSC was 16.2％-19.8％.The survival rate of soft-shelled turtle was 88.83％,the yield of aquiculture area was 1.29 t/hm2,the yield of planting and aquiculture system was 129 kg/hm2,and the income increased by 17900-23000 yuan/hm2.The research indicated that this model of peach and soft-shelled turtle had better water quality indexes,remarkable economic and ecological benefits,which was a kind of model with the advantages of resource recycling,energy saving and environmental protection,high ecological efficiency and high product quality.
