Embodiment 1

[0031] An ecological planting and breeding method for cultivating shrimps and crabs in a lotus pond, comprising the following steps:

[0032] S1. Reconstruction and pretreatment of lotus root fields: Select a location with sufficient water sources and flat terrain for lotus root field reconstruction. The specific method of said lotus root field reconstruction is as follows: along the outer edge of the ridge around the lotus root field to 7-8m in the lotus root field, excavate the lotus field. Ring-shaped ditch, the upper mouth of the annular ditch is 8-10m wide, the lower mouth is 4-6m wide, 1.5-2m deep, and the ridge is 1.0-1.2m higher than the flat field; at the same time, the two ends of the lotus field are respectively provided with water inlets and drainage outlet, set a mesh with 6 to 8 holes / cm at the drainage outlet, set up an escape net on the ridge, the height of the escape net is 60 to 80 cm, and place 20 cm at the water inlet. ~30 mesh bag; then sprinkle 50~100kg / m...

Abstract

The invention discloses an ecological planting and breeding method for intercropping shrimps and crabs in a lotus pond. The ecological planting and breeding method comprises the following steps of S1, transformation and pretreatment of a lotus root field, S2, throwing and feeding management of juvenile river crabs, S3, planting of lotus roots, S4, throwing and feeding management of juvenile crayfishes, S5, water quality adjustment and substrate improvement, and S6, fishing of the crayfishes and the river crabs and harvesting of the lotus roots. According to the method, the culture cycle and life habits of the crayfishes and the river crabs are comprehensively considered, the culture space is effectively utilized through the biological complementary relation, use of investment such as chemical fertilizers is reduced, stable yield and income of the pond are promoted, and culture benefits are increased. Besides, the pilinuts are selected and modified, and the obtained modified pilinuts can be tightly combined with corn flour, bean bran and rice bran in a feed formula, so that the dispersion time of the prepared compound feed in water is longer, the utilization rate of the feed is increased, and the cultivation period of the crayfishes and the river crabs is shortened.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting and breeding, in particular to an ecological planting and breeding method for cultivating shrimps and crabs in a lotus pond. Background technique [0002] Lotus root (Nelumbo nucifera Gaertn) is a perennial large aquatic herb of the water lily family. Can be used as medicine, there have been a lot of studies showing that lotus root extract has a wide range of pharmacological effects: antioxidant and free radical scavenging, anti-aging, liver protection, anti-HIV activity, anti-inflammatory effect, autoimmune disease inhibition, antipyretic Potential, weight loss, hypoglycemic and psychopharmacological effects, therefore, lotus root has excellent medicinal value and edible value. Lotus roots are generally planted in ponds, and how to improve the yield of lotus roots has always been the focus of research. Crayfish, also known as Procambarus clarkii, is an adult shrimp with a dark red...
