Problems solved by technology

[0006] However, the model of cultivating snakeheaded fish in the lotus field has just emerged, and there is no corresponding technical reference, so it is not very mature, and many technical details need to be further improved.

Embodiment

[0030] Process a. Selection and reconstruction of lotus root field

[0031] For lotus root fields, pits and ponds are selected or transformed directly from low-lying rice fields. This type of field is low-lying, and other general non-aquatic crops are prone to waterlogging, and often cannot harvest normally, resulting in large losses. Moreover, this type of farmland retains water , fat retention ability are relatively strong, more suitable for the development of lotus root field fish farming. The field area should not be too small, preferably 4 to 8 mu. After the location of the lotus root field is selected, a ditch with a width of 1-1.4 m and a depth of 1-1.4 m is excavated around the lotus field. In this embodiment, the ditch is 1.2 m wide and 1.2 m deep; In the area, the ditch is properly widened to 3 to 5 meters to facilitate feeding of snakeheaded fish. In addition, a cross-shaped fish ditch with a width of 0.6-1 m and a depth of 0.6-1 m is dug in the middle. In this...

Abstract

The invention relates to a method for ophiocephalus argus intercropping in a nelumbo nucifera field. The method includes the following steps of nelumbo nucifera field selection and reconstruction, nelumbo nucifera seed cultivation, fingerling breeding and daily managing. Based on the ecological economics and ecological agriculture theories, nelumbo nucifera planting and ophiocephalus argus breeding are organically combined, space, land resources and water resources are sufficiently utilized, and special agricultural product production, a water quality improvement through an ecological cycle and beautiful rural reconstruction are organically combined. Data of ophiocephalus argus specifications, ophiocephalus argus density and others in the intercropping method are obtained through comparative test screening. While growth of nelumbo nucifera is guaranteed, great economical benefits can be obtained. In addition, the ophiocephalus argus is bred in the nelumbo nucifera field, which helps plant diseases and insect pests to be reduced. Meanwhile, excreta of the ophiocephalus argus and residual feeds are sufficiently provided as sufficient fertilizer for the growth of the nelumbo nucifera, so that agricultural cost is reduced, income increasing of farmers is achieved, and ecological agriculture which saves resources, is environmentally friendly and has sustainable development is achieved.

Description

technical field [0001] The invention relates to a method for nesting black fish in lotus root fields. Background technique [0002] lotus root ( Nelumbo nucifera ), also known as lotus, lotus, anciently known as hibiscus, Hanyu, hibiscus, etc., are perennial herbaceous plants. Lotus root is edible with its enlarged rhizome (commonly known as lotus root) and its fruit lotus seeds. It is rich in nutritional value and is deeply loved by the masses. At the same time, lotus root has good medical value, and all parts of its whole body can be used as medicine.
